How Many Neon Tetras in a 10 Gallon Tank?

Neon tetras are peaceful schooling fish that require a peaceful and safe environment to thrive. A tank that offers plenty of hiding spaces and carpet plants for shade will suit their needs perfectly; aggressive or larger tank mates could become stressful and cause them harm.

Space needs for fish can vary widely depending on their species’ size and social behavior, including schooling behavior in groups like Neon Tetras that require additional space.


Variety is key when keeping various fish species, and this is particularly true of a community tank filled with different types of aquatic creatures. To ensure your tank can accommodate enough neon tetras for all the species in it, know its size and how many neon tetras it can hold so as to avoid overcrowding your aquarium.

Neon tetras are fast swimmers that require plenty of room in a tank, preferring either the bottom or top layer. Their exact numbers depend on other species such as guppies which tend to overpopulate their tanks more rapidly; otherwise a couple could quickly overcrowd your tank in just months!

An effective rule of thumb when it comes to housing neon tetras safely in their tank is using the one inch rule per gallon of water. Since they don’t reach more than 1.75 inches in length, this should work just fine and allow you to safely house six neon tetras in your 10 gallon aquarium.

Consider whether or not the fish you plan on housing with your Neon tetras will co-exist peacefully in an aquarium environment. Schooling fish such as these require plenty of room; larger or aggressive varieties could exacerbate stress levels for these peaceful schoolers and may even prey upon them!

Environment wise, your tank should be clean and filtered with temperatures around 65degF. In terms of feeding the fish a varied diet and conducting regular water changes, as well as providing sufficient oxygen levels, an air pump may provide necessary augmentation. Finally, wait 4-6 weeks before adding new species as this gives beneficial bacteria time to establish themselves within the environment.


Neon tetras are peaceful shoaling fish that prefer living in groups of three or more. A vibrant addition to any aquarium, their colors will surely draw the eye.

These fish are also omnivores, meaning that they can survive on a variety of foods in captivity and in nature; in particular, organic matter from dead vegetation and insect larvae form an essential source of sustenance for neon tetras in an aquarium environment. When feeding neon tetras twice daily with standard flake food in your tank, crush the flakes before feeding to reduce any risks of choking hazards.

If you decide to add other fish species to the tank with neon tetras, be sure they fit within its parameters. Aggressive or larger species could stress out or prey upon neon tetras; additionally, incompatible ones could contaminate it with waste such as ammonia and nitrates that pollute its waters.

Neon tetras are usually found living in slow-moving blackwater streams in their natural environments, where these dark environments help conceal their hiding places from predators and protect them. You can replicate this environment in your tank using dark substrate and providing plenty of dense vegetation and driftwood – don’t forget about providing plenty of hiding spots for them, too!

As well, you should select tank mates that won’t compete for food with neon tetras. Fish that are susceptible to parasites like Ich can spread the deadly illness to other fish in your tank and cause internal bleeding and death – to prevent this, any new additions should only be introduced after it has been cycled and is stocked with healthy specimens.

One method to prevent ich in your aquarium is testing its water regularly for nitrates and ammonia levels, and changing or cleaning out filters as necessary if necessary if levels reach hazardous levels. Doing this will prevent ammonia/nitrate build-up that could kill off fish in your tank and would require only selecting species that can tolerate high concentrations of toxic substances like ammonia.


Neon tetras are peaceful fish that thrive in well-kept, clean tank environments, enjoying swimming around decorations while gliding through the water. While these peaceful fish can co-habitate with other types such as guppies or bettas, neon tetras perform best when provided ample space in a larger tank; small tanks can become stressful to them which leads to aggressive behavior from them; moreover, neon tetras are known for being active swimmers so more room should be provided so they have plenty of space when moving through water and decorations gliding through decorations while gliding through water surfaces while swimming through decorations; peaceful yet active swimmers require plenty of room.

A 10 gallon aquarium can house up to five neon tetras, but it is essential that their social needs be considered as well. Neon tetras are schooling fish that prefer living together. Housing them together helps them cope with stress and other environmental factors more easily while schooling also allows the fish to display natural behaviors without becoming distressed or stressed out.

When it comes to neon tetras in a 10 gallon tank, the “one inch rule” can provide an approximate guideline as to their placement; however, this does not take into account factors like their size or behavior. A full grown neon tetra measures 1.75 inches so there should only be enough room for about six fish comfortably in this manner.

One way to ensure that neon tetras have plenty of space in their tank is to add live aquarium plants, like Cryptocoryne wendtii, Ludwigia repens or Vallisneria species. These aquatic plants can add variety while increasing oxygen levels. Some recommended aquatic plants for neon tetra tanks include these.

Before introducing neon tetras into a new tank, it is crucial that it cycles for at least six weeks in order to allow beneficial bacteria to flourish and stabilize its water parameters. Furthermore, regular water changes must take place to remove waste from the aquarium as well as feeding regularly and monitoring for signs of illness such as loss of coloration or erratic swimming patterns that impede feeding or decrease appetite – symptoms of which include loss of coloration, abnormal swimming patterns or decreased appetite.


Neon tetras are omnivorous fish that enjoy eating a varied diet of high-quality flakes and pellets as well as frozen or live foods like brine shrimp and daphnia. Carrots can also be enjoyed, although these should first be boiled to ensure their pieces fit comfortably within their mouths.

Neon tetras flourish when their aquarium is packed with plants and algae, as this mimics their natural habitat of slow-moving blackwater streams. Neon tetras like to hide amongst the foliage so make sure there are enough hiding places available – this will also reduce stress levels and minimize accidents from nibbling!

When selecting aquatic plants for your aquarium, choose ones with small leaves and avoid those with larger ones; larger leaves attract tetras to the surface and can become an irritation to their natural behavior. Also avoid decorative rocks as these could distract the tetras’ attention away from important parts of the tank.

Neon tetras thrive in waters with soft, slightly acidic conditions similar to their natural habitat in the Amazon river basin. While they’ll tolerate various substrate types, aragonite sand should be avoided since this will leach calcium carbonate into the water, potentially raising its GH, KH, and pH levels.

Although neon tetras can be kept alone, they thrive best when kept in schools of fish. Their wild counterparts live together in schools numbering thousands. Housing them too closely may cause stress or other health issues.

Keep no more than six tetras in a 10 gallon tank to allow them to flourish and display their vibrant colors at their best. This will allow them to thrive and provide many beautiful displays of vibrant hues!

The one inch per gallon rule does not take into account height; therefore, fish that are taller than an average neon tetra will require a larger tank. Furthermore, some species produce high waste output and this necessitates either more frequent changes of aquarium water or larger tanks to prevent overtaxing the filter system.

What is a Refugium?

A refugium is an area in a sump tank or separate unit which contains mud/sand/plants to act as natural filtration in saltwater marine systems, filtering out harmful nitrate and phosphate while providing habitat for marine microfauna such as copepods.

Reefers often opt for caulerpa or chaetomorpha algae in their refugium as these rapidly-growing varieties can effectively export nitrates and phosphates out of their system. Lighting may need to be adjusted either on an alternate cycle basis or continuously throughout their use.

Biological Filtration

Refugiums provide an alternative way of filtering waste that would normally settle on rocks and deep sand in your tank by feeding on detritus and food waste; amphipods and copepods feed off of this detritus while also helping regulate nitrate and phosphate levels for less frequent and smaller water changes. Furthermore, many saltwater fish keepers will add an additional filtering system by growing Caulerpa macroalgae above these surfaces which will absorb excess nutrients before expending them back into their main aquarium when returning them into its main environment.

A refugium provides an ideal space for small organisms that would otherwise be vulnerable to being eaten by predatory fish in your main tank, enabling them to reproduce freely and creating additional food sources for your fish and inverts – especially filefish, black bandit angelfish and other fussy feeders that may reside within your reef tank.

Substrates used in a saltwater refugium typically consist of rubble rock which provides plenty of surface area for bacteria to attach themselves. Some hobbyists will create an anaerobic chamber in an ancillary tank which attracts anaerobes as a potential home, serving also as an effective scouring pad against nitrogen wastes in your tank water.

Refugium mud is another popular substrate choice, helping restore trace elements in the water and providing a great environment for bacteria to flourish. However, it should be noted that using mud and algae beds does not replace regular filter systems or RO/DI water for water purification purposes.

Polychaete and bristle worm colonies can provide another effective form of biological filtration in a refugium, as they devour any detritus left behind from micro crustaceans as they sift through the sand in search of sustenance. Their presence makes refugia an appealing feature to aquarists.

Detritus Removing

Reef aquarium hobbyists are often advised to incorporate a refugium into their tank as part of the solution to maintain high-quality water in their tank, yet many remain uncertain what a refugium actually entails or how it works. To help answer some questions on what exactly constitutes a refugium and its purpose.

Refugiums offer multiple advantages to an aquarium ecosystem, the primary of which is providing space for macroalgae to grow. When algae blooms, it feeds on organic waste from fish waste or leftover food in the tank before breaking it down to produce organic nitrogen that can be used by plants for growth – this process eliminates nitrates and phosphates from water sources while simultaneously filtering waste out. Refugiums play an integral part in this cycle by filtering out impurities like nitrates/phosphates while filtering out waste into organic form for use by plant life – eliminating their presence from our aquatic environments!

Macroalgae may not be ideal for display tanks as its presence can be invasive, which is why saltwater refugiums are essential – they allow you to keep macroalgae contained within its confines and stop it from overtaking your reef tank. If its growth becomes excessive however, a dilute solution of hydrogen peroxide might be needed in order to eradicate it completely.

Refugiums provide an ideal habitat for micro-crustaceans such as Copepods to thrive in your reef tank, helping maintain optimal water quality by devouring detritus and other decaying material that might otherwise negatively impact water quality. Furthermore, Copepods serve as food sources for many varieties of coral as well as some fussy feeders like filefish and black bandit angelfish.

Refugium substrate may differ from your display tank in several ways, including using something unusual such as mud. Mud is especially good at helping caulerpa establish itself and stay anchored, while Chaetomorpha “cheato” remains one of the most popular macroalgae for saltwater refugiums due to being easy to find, fast growing and highly effective at expelling nitrates and phosphates from waterways – though its unattractive appearance doesn’t add any beauty! Regardless, function should always come before form when creating an environment dedicated to growing caulerpa.

If space constraints do not permit for a sump tank with its own refugium, an alternative might be purchasing one that can hang or side-mount instead. These models tend to be much cheaper while still offering all the advantages associated with refugia.


Saltwater refugiums can help to lower nitrates and phosphates levels in your reef tank by encouraging macro algae to absorb excess nutrients from the reef water, before being filtered out of the refugium through filters – thus decreasing their chance of entering your display tank.

There are various approaches to setting up a refugium, from clean and modern designs using biobricks or pod hotels to more natural methods with live sand or miracle mud and rocks for added macroalgae growth. Whatever design you opt for, it is key that you seed it with appropriate macro algae species for maximum success in saltwater refugium environments.

Chaetomorpha or “chaeto”, for short, is the optimal macro algae to use in saltwater refugiums as it grows quickly and is very hardy. Chaeto also acts as an effective way of filtering harmful nitrates and phosphates out of your reef tanks water system by exporting them out through caulerpa racemosa’s fast growth but slower spread rates compared to chaeto. For optimal performance it’s wise to combine both varieties by seeding both into your saltwater refugium!

Seed your saltwater refugium with macro algae at the beginning of every cycle to maximize their effectiveness in absorbing unwanted nutrients. At this same time, add copepods so they can feed off of excess nitrates and phosphates being exported out of your tank – creating ecological harmony within your saltwater reef tank! This practice allows synchronized seeding to help create ecological music in your saltwater reef tank.

Refugiums provide more than just nitrate reduction; they also facilitate healthy corals by offering them a safe environment to reproduce in. Sometimes corals require extra room to grow properly, making a saltwater refugium the ideal place for them to flourish and become the focal point of any home aquarium.

Ecosystem Design

Dependent upon its configuration, a refugium can also serve as an ideal environment for growing organisms that would not thrive in your main reef tank, such as cyanobacteria to reduce nitrates or macroalgae that export nutrients.

Saltwater refugiums use algae as their main micro-organism of choice in order to export nitrates and phosphates from your aquarium. Cheato, caulerpa or another macroalgae species commonly seen in reef tanks should all work equally effectively at doing this job.

As algae can quickly and become invasive in a display tank, it is best contained to the refugium for easy removal when necessary. Some macroalgae species excel at exporting nutrients more readily than others – common examples being Chaetomorpha (cheato) and Caulerpa racemosa.

If you want the maximum return for your investment, a refugium fed with the nutrient rich wastewater from your display tank is an effective strategy. By giving organisms ample opportunity to grow safely back into their display tanks without fear of being eaten, a regular source of “feeder” organisms is created for feeding larger creatures and corals.

Many refugiums feature a thick layer of mud or sand to replenish lost trace elements and foster beneficial bacteria colonies, creating an environment in which nitrate-reducing anaerobic zones may form and further lower levels of nitrates and phosphates in your display tank.

Saltwater refugiums can help your reef tank lower nutrient levels by providing an environment for copepods to breed in. Copepods are essential food sources for many fish species, particularly blue mandarin dragonet. A large enough refugium will allow enough populations of copepods to form before safely returning them back into your display tank where they will provide continuous and free sustenance for your reef fish.

How to Lower Nitrates in a Freshwater Aquarium

Nitrates are caused by various sources, including fish poop and uneaten food debris that pollutes the water, eventually breaking down into ammonia (which can kill fish) and eventually into less harmful forms like nitrates.

There are various methods you can employ to decrease nitrate levels in a freshwater aquarium, including regular water changes and the presence of live plants. You may also choose special filters designed to reduce nitrates – these filters can usually be found at aquarium stores.

Water Change

Are You A Longtime Keeper of Fish? If you keep fish, chances are you are familiar with the three harmful substances that can accumulate in an aquarium: ammonia, nitrite, and nitrate. Nitrate forms part of a nitrogen cycle system when functioning correctly; when levels remain below an optimal threshold level it can be converted to non-toxic nitrogen gas without harm to fish or humans. Water changes are one way of keeping these levels down; other solutions may exist as well.

Nitrifying bacteria (nitrosomonas) provide beneficial nitrifying bacteria with ammonia from fish waste and decaying plant material to convert to nitrite and then nitrate, but most fishkeepers must perform regular water changes due to rising concentrations of nitrate over time causing muscle tremors and disfigurement; it should therefore be removed by replacing some percentage of tank water with fresh, dechlorinated tap water from a different source.

There are devices designed to reduce nitrates in aquarium water, including nitrate-adsorbing filter media and anaerobic denitrifying biofilters, but these solutions can be expensive and take up space in your tank. Furthermore, these filters need frequent changes; thus making water changes the most efficient solution to combating nitrate levels.

Plants are fantastic at lowering nitrate levels in saltwater and tropical freshwater systems. Macroalgae are particularly helpful at quickly absorbing nitrates and waste products; this type of macroalgae should be grown in a sump tank as part of a refugium setup; regular clipping or removal will keep it from overgrowing and depleting oxygen supply from your aquarium.

Feeding Less

Although high levels of nitrates will not necessarily kill your fish, they can place it under tremendous strain. Your fish could experience loss of energy and become lethargic; metabolism could slow; sores could develop on skin; while extreme levels could even stunt growth.

One of the main culprits behind high nitrate levels in freshwater aquariums is overfeeding. If your fish consume more food than they can consume, their waste rots and produces nitrates – something which can be managed by only providing feed twice daily and making sure all your meals are eaten within two minutes of being introduced into their environment.

An aquarium that features abundant plant life will help to keep nitrate levels down by absorbing much of the ammonia and nitrite produced in your tank, while filter media that absorbs nitrates may also be effective at mitigating their buildup.

Though these methods may help reduce nitrates, the most efficient and effective way is through regular water changes. When you change the water, all the nitrates within that volume of water are removed – as long as you use tap water that has lower nitrate levels than your aquarium water and make changes at least 50% of the time, your nitrate levels should decrease significantly.

One beneficial way of testing your water is with nitrate testing strips. These strips can detect ammonia, nitrite and nitrate levels in your aquarium’s environment and use this information to detect problems early and manage them before they escalate into bigger issues. When detect rising levels of nitrates it’s essential that regular water changes and cleaning be conducted immediately if you detect an increase.

Live Plants

Nitrates in an aquarium are produced as by-products of the nitrogen cycle, in which beneficial bacteria convert fish waste and uneaten food into less harmful substances. While this process is necessary for your tank’s inhabitants, if not managed appropriately it can result in high levels of nitrates which must then be decreased through regular water changes, feeding schedule changes, or other methods.

Conducting water changes is the fastest and most efficient way to bring down nitrate levels in an aquarium quickly. Nitrates may be present in tapwater used for your aquarium, and by replacing this water with clean freshwater from your tap, the nitrate levels may quickly decline to safe levels. Before beginning water changes however, you should test your tapwater for polluted levels first as adding polluted tapwater may lead to unexpected issues with your aquarium.

Live plants can help reduce nitrate levels in an aquarium by using ammonia and nitrite produced in an aquarium to produce life. Some great aquatic plant options for this purpose are crypts, mosses, sword ferns and Pistia stratiotes (the mangrove plant), while common houseplants like Pothos, Philodendrons or Lucky Bamboo may also work to remove nitrates from water sources.

An elevated nitrate level in any freshwater aquarium is a serious cause for concern, and should be monitored closely in order to avoid health problems for its inhabitants. Regular water changes and proper feeding schedule can help lower nitrate levels; be diligent and observe regularly – your aquarium’s chemical makeup should manage itself by itself!


Controlling ammonia, nitrite, and nitrate levels is essential to creating an aquarium with healthy fish that looks beautiful. Fish waste accumulates in an aquarium’s ecosystem over time, producing nitrates – the most harmful element among them all.

Nitrates in your tank can be taken up by plants, but they cannot absorb enough to balance out your system. Therefore, it’s essential that some form of nitrate-reducing filter media be installed so that bacteria will take up and convert nitrates to less harmful forms.

Siporax (commonly referred to as borax) has long been an aquarium hobby favorite, used to foster the growth of bacteria that reduce nitrates in your tank. Available in various forms – including nitrate pads that absorb them – Siporax is widely available at pet stores and online.

Ceramic filter media that promotes the growth of bacteria that reduce nitrates and ammonia can also be an effective means of nitrate removal, known as bio-media, works well in both freshwater and reef tanks alike. MarinePure ceramic material comes in round spheres for this purpose – fitting easily into most filters.

An effective natural method to lower nitrate levels is pruning live plants on a regular basis, to keep their leaves from becoming too lush, which could result in too much nutrient uptake or equipment clogs. Frogbit is an excellent plant to trim for both aesthetics and lower nitrate levels in aquariums; duckweed and water sprites should also be regularly pruned since too thick foliage could clog filters and cause other issues.

Natural Filters

Nitrate levels that reach toxic levels in an aquarium can become toxic to its inhabitants, including fish and other creatures. Therefore, it’s vitally important that nitrate levels be checked often and done what’s possible to keep them low; whether that means regular water changes, providing only enough food and limiting fish populations as needed or using natural nitrate removers like reverse osmosis technology, there are various methods available to you for keeping freshwater aquarium nitrate levels under control.

Nitrates are produced when ammonia produced from fish waste and nitrites produced by cycling bacteria are converted to nitrate by microorganisms in the water, and then consumed by blue-green algae (cyanobacteria), becoming food sources that may prove fatal for aquarium inhabitants.

Implementing periodic partial water changes is an excellent way to quickly lower nitrate levels in your tank and retest for their nitrate content. Even if full water changes aren’t feasible, try doing at least 50 percent every week and monitor their effects.

Nitrate levels can also be reduced naturally and easily by adding nitrate-absorbing filter media, like API’s Nitra-Zorb, to your tank. Not only is it economical and rechargeable, it’s also simple to use: simply position near an outflow or powerhead for constant waterflow.

An effective natural method for lowering nitrates is keeping a heavily planted tank. Plants will help absorb the ammonia, nitrite and nitrate produced by fish and decaying plants to lower nitrate levels naturally. If live plants cannot be grown, consider adding macroalgae or mangrove plants into your aquarium as these will absorb waste products to bring down levels further – which is why reef tanks feature so much macroalgae! This phenomenon also makes reef tanks so popular among marine aquarists!

What Kind of Water For Goldfish?

Goldfish thrive best when fed tap water that has been pretreated with de-chlorinator and conditioner devices. Furthermore, regular partial water changes should be conducted to maintain high dissolved oxygen levels in their environment.

Bottled spring water is an excellent choice as it contains all of the minerals essential for maintaining goldfish health, as well as being free from chlorine and chloramines.

Tap water

Goldfish are hardy fish, yet they cannot live in untreated tap water due to chlorine, chloramines and heavy metals present. Goldfish require a water conditioner – either online or from pet stores – in order to remove harmful elements and keep their tank healthy and safe for their inhabitants. A filter should also be installed regularly so as to maintain clean conditions for your goldfish tank.

Before adding tap water to your tank, always perform a water test using a quality test kit. A quality water test kit will enable you to assess its quality by showing whether it has an acceptable pH level and hardness level, in addition to informing whether or not its safe for goldfish consumption.

As with the above method, when choosing bottled water specifically made for aquariums it’s essential that it includes an inbuilt water conditioner to treat and filter your tank water as you pour. Some pet stores even sell pre-conditioned bottled water which makes changing your tank’s water easy!

Goldfish should be kept in water that falls between pH7.0-7.5 to ensure optimal conditions. Too acidic or alkaline water may stress out their health, requiring frequent testing with a water conditioner in order to prevent illness and stress inducing effects on them. You can minimize this by testing regularly as well as adding conditioners into their environment.

Alternative Method: Distilled Water can also be an option. Distilled water is very pure, yet can be unhealthy for goldfish if left without being remineralized. You can remineralize distilled water using a water conditioner which will dissolve minerals and heavy metals found within it. You could also allow it to sit out for 24 hours so it dechlorinates itself naturally.

Bottled water

Goldfish are hardy freshwater fish species. As long as temperatures, pH levels, and hardness levels meet specific standards – such as ideal tank water temperatures of between 68-74 degrees Fahrenheit for ideal tank conditions – goldfish can survive in virtually all environments that meet these parameters; however, saltwater environments cannot support goldfish living.

Even though goldfish are hardy fish, they are sensitive to water conditions and can be killed by sudden changes. Therefore, it’s crucial that you monitor and make changes as necessary in your aquarium water – using a high-quality test kit will enable you to do so more easily.

Tap water can be safe for goldfish, provided it has been properly treated to eliminate chlorine and other potentially toxic chemicals, and heavy metals that could potentially damage their gills.

Bottled water can also provide goldfish with essential hydration. Available at most pet stores and aquarium stores alike, bottled water makes for a convenient source of nourishment that’s easily used within an aquarium environment. However, when selecting your water supply it’s essential not to choose one with added chemicals or flavors, as these could harm goldfish health. Likewise, reverse osmosis water could contain potentially toxic elements that are detrimental to goldfish health.

Boiling water should also be avoided to minimize toxic emissions into your aquarium and buildup of carbon dioxide gas that could harm goldfish. If this becomes necessary for any reason, allow it to cool before adding it back into the tank.

Distilled water isn’t recommended as an aquarium choice due to the absence of minerals essential for their wellbeing, though it may be used as an emergency backup in tanks that lose water due to evaporation. Distilled water has not been sterilized with chlorine or any other chemical; furthermore, well water can harbor bacteria and harmful elements which could compromise their health.

Spring water

Goldfish are extremely sensitive to environmental changes, such as changes to temperature and pH levels in their environment, as well as any diet rich in minerals and vitamins. To keep them happy and healthy, use only distilled or bottled water in their aquarium, changing out at least weekly; or use tap water treated with a water conditioner beforehand (this will remove chlorine chloramine and maintain an appropriate pH value in their tank).

Your local grocery store likely carries bottles of fresh spring water that is perfect for goldfish aquariums. Just be careful that it does not contain chlorine or chloramine and test for hardness before adding it into their tank.

Springwater is a source of fresh, ground-sourced water that emerges from underground reservoirs or conduits, and may come in the form of natural or man-made reservoirs. Spring water tends to be healthier than tap water due to being free from pollution; however, bacteria, fertilizers, or pesticides could still exist within its composition and quality can vary throughout the year.

No matter if you use tap or spring water, it is imperative to use a high quality water conditioner. This will protect against chlorine, chloramine, and heavy metals from harming your fish gills, while having an effective water testing kit allows you to monitor pH and chemical levels within your aquarium water.

Well water may also be suitable for your goldfish aquarium; however, this is often filled with bacteria and contaminants and does not offer as clean a surface as bottled or tap water does. Furthermore, finding spring water with suitable pH levels for goldfish may prove more challenging than expected.

Distilled water

Goldfish are hardy creatures that can adapt to most water conditions, though they cannot tolerate salinities higher than zero for extended periods. Goldfish require specific mineral levels for optimal growth – tap and bottled waters provide this mineral supplementation; temperature should also play an essential role; ideal temperatures range between 62-72deg Fahrenheit for optimal living conditions.

Tap water is often the go-to option when keeping goldfish tanks. Unfortunately, though, due to chlorine and chloramine levels that could be present in it causing serious health problems for your goldfish. A water test kit can help determine if your tap water is safe by testing for chlorine levels, pH balance, hardness levels, heavy metal contamination levels as well as knowing whether any heavy metals exist in it.

Prior to adding bottled water into your tank, it is a wise move to do a test run to make sure that it is free from chlorine, chloramines and heavy metals. Bottled water may be costly when used in larger aquariums but is ideal for smaller goldfish tanks.

Finally, spring water may also be beneficial in providing optimal conditions for goldfish tanks if treated properly. Spring water contains essential minerals for goldfish to thrive while simultaneously being free from bacteria, parasites, or fertilizers which could compromise their wellbeing.

Distilled water can provide your goldfish with another option for healthy living conditions, as it has been purified and free from chlorine, chloramines, and heavy metals. Distilled water is ideal for replacing evaporated water in your tank; however, due to being devoid of essential minerals for health reasons it would be prudent to utilize a water conditioner with remineralizing capabilities to make this alternative healthy for goldfish.

Well water may also be suitable for your goldfish, though this should be avoided. Well water often contains harmful heavy metals like zinc, copper and cadmium which are toxic to goldfish in large doses and may damage their gills as well as harmful bacteria which resides therein.

What You Need to Know Before Getting a Betta Fish

Also known as Siamese fighting fish, betta fish is a beautiful fish with colored tails. Bettas are the most popular fish in aquariums globally, perhaps due to their pleasant color. 

Pet fish require less work as it is confined in the aquarium. If you wish to keep a betta fish, here is a guide to help you.

Invest in a Big Aquarium 

These fish species swim a lot and hence need ample space. Experts recommend a tank that holds a minimum of 5 gallons. If you decide to add more pets from the same family, get a bigger space for them.  

Though the fish size varies, the average length of a grown betta is around 2.5 – 3 inches without the tail. Vibrant, healthy fish have big, long tails that are open wide and flow smoothly. 

Note that the fish love to jump. Keep the aquarium covered, or if you wish to leave it open, provide enough space between the top of the tank and the water.  

Unlike the widespread misinformation, you cannot keep betta fish in small bowls. Bettas need more than bowls.

Do Betta Fish Love Company?

One rule of thumb is never put two male betta fish together! Bettas are also known as Siamese fighting fish for this reason. 

Betta fish have poor social skills and prefer their own space. Both male and female betta fish can accommodate snails, cory catfish, feeder guppies, and shrimp and coexist peacefully. However, two Siamese cannot stay in the same aquarium.

If you find non-aggressive female bettas, you can place two of them in one container with enough water. 

What to Put in the Aquarium

Bettas hide when nervous or fearful and swim around decorations or plants to stimulate their brains. You need to provide ‘hiding spots’ for the betta fish

Though the choice of aquarium décor is personal, avoid pointed or sharp items in the aquarium as they can hurt the fish when swimming. 

Also, remember these types of fish need plenty of space to swim around. Hence if you love lots of decorations, invest in a bigger tank. You can have artificial or natural plants as they all work with the fish. 

Add Plants in the Aquarium

Aquatic plants keep the water oxygenated and clean, enrich your pet and make the environment attractive. Adding some live plants to the tank hosting the fish is a great plus. 

When choosing plants, ensure you settle for those that do not grow too large or tall. Betta loves plants with dense and long leaves like Java Ferns, Marimo Moss Balls, Amazon Sword, and Anubias Nana. 

Water Temperature

Tropical fish like betta thrive in warm waters. Since it is impossible to consistently maintain a temperature above 75 degrees, buy a heater to keep the water temperature at 78 – 80 degrees. 

You will need a safe aquarium thermometer to ensure constant water temperature. When the surrounding temperatures drop, betta fish become lethargic and withdrawn as they are sensitive to changes in water parameters.

Betta Fish Diet

Living things thrive when fed on their most natural diet. Larvae and small insects are the best for betta fish due to their carnivorous nature. Frozen food like bloodworms and brine shrimp will also work. Betta fish need foods rich in protein and varied for their healthy development. 

The stomach size of a betta fish is the size of its eyeball, so one feed a day is enough. Once the betta stops actively feeding, do not give more food. If there is uneaten food that builds at the tank bottom, it will pollute the water.  


You are now qualified to adopt a betta fish! The above tips are essential to help you start your journey of fish keeping. 

The Dos and Don’ts Of Taking Care Of A Goldfish

Goldfish are one of the most popular pets in the world, and while they’re relatively low maintenance (they don’t need to be walked or fed a lot), there’s still a lot you can do to make their lives healthier and more enjoyable. Here are some tips for taking care of your goldfish.

Do Set Up A Healthy Environment For Your Goldfish

Like any other living being, your goldfish needs a healthy environment to thrive. The size of your tank is one factor, because a large enough tank ensures that it won’t run out of oxygen or become too cold (Goldfish are tropical fish).

Other important factors include water parameters and filtration. The water in your tank should be filtered to remove waste and supply fresh oxygen. It should also have the right pH balance, temperature, and water hardness.

Don’t Under Feed Your Fish Or Give It Too Much Food

One thing that you should never do is overfeed your goldfish. Goldfish have a fast metabolism; if your goldfish eat more than their bodies can process, they will die. If you notice extra food in the tank or your goldfish aren’t growing as quickly as they could be, try cutting back on how much you feed them.

They can also become constipated if they’re fed too much food, so you should only feed your goldfish a pea-sized amount of food at a time. If the fish refuses to eat for more than three days, take it to a pet store that specializes in aquatic life.

Don’t Keep Goldfish With Other Species Of Fish

Many owners of freshwater fish mix different species in their tanks, but this is one instance where it’s important to follow the rules. Goldfish are natural scavengers that eat pretty much everything they can find, so keeping them with smaller and more vulnerable fish could lead to a disastrous situation.

Other species of fish can also make your goldfish sick if they eat the wrong foods. If you have to feed both species of fish together, only put healthy food into the tank and monitor closely what happens. 

Do Get Your Goldfish Some Friends

Goldfish are social animals. They’re happiest in schools. If you only have one goldfish, give it lots of space so that it can swim freely. A large school of several goldfish is even better for an environment that’s conducive to goldfish growth and health.  

At the same time, don’t overcrowd the aquarium. Goldfish produce a lot of waste, and an overcrowded tank might make the water more contaminated than it should be.

Don’t Forget About Temperature Or Light Sources When Taking Care Of Your Fish

Goldfish are relatively simple to care for, but they still need temperatures within the range of 65 and 85 degrees Fahrenheit (18 and 35 degrees Celsius). They also require light, preferably full-spectrum light that simulates natural sunlight.

Do Make Sure To Clean The Tank Every Week And Change The Water Bi-Weekly

You’ll also want to make sure the tank is clean. A dirty fish tank can lead to illness in your goldfish, so you must do regular water changes or use other methods for keeping the tank clean. Ideally, you should clean the tank every week and change about one-third of the water every two weeks.

If Your Goldfish Gets Sick, Do Take It To The Vet

Goldfish often get ill because they’re kept in small spaces with tons of other fish. If your goldfish gets sick, you should take it to a pet store or a veterinarian who specializes in exotic pets. Either way, an illness can be fatal if not treated right away.

Don’t Buy An Expensive Aquarium With Lots Of Decorations 

This can be dangerous to small fish. Goldfish aren’t as hardy as other fish, so if you buy a tank that’s too large for them (or put goldfish in a tank with decorations they can get stuck on or hurt themselves on), there’s a good chance your fish will die. 

This is more of an issue than it might seem. Unfortunately, many pet owners think goldfish are so hardy that they don’t need to worry about them dying in an aquarium. Goldfish can hurt themselves on decorations by getting stuck on decorations or bumping into them and getting injured.

Taking Care Of A Goldfish

Do Make Sure You Have A Backup Filter In Case One Breaks Down 

If you’re relying on one filter to take care of your tank, it can be a disaster if something goes wrong with it. Ideally, if you do have one filter that’s handling all the work for the aquarium, you should also have a backup in case the primary filter breaks down.

If you’re a goldfish owner, make sure to follow these dos and don’ts for taking care of your pet. Goldfish are one of the most popular pets because they are easy to take care of and do not require much space or attention. That doesn’t give you an excuse to neglect them.  Like any living thing, they will thrive with the proper care. Once they do, as an owner, you’ll feel the pride to see them do well.

A Beginners Aquarium Guide to Successful Fish Keeping

So, you are thinking about joining one of the most popular hobbies in the world by diving into the crazy world of fish keeping and aquarium maintenance? In this aquarium guide, we will be running you through the fundamentals when it comes to fish keeping, looking after your aquarium tank, water care, equipment, and the best fish for a beginner.

Owning fish is almost like a full-time job itself, and as your aquarium or as many fish keepers say, “community” grows, so will your responsibilities. You cannot simply neglect your fish nor clean your tank; otherwise, there will be unfortunate consequences for the life forms that you are looking after.

Being an aquarium owner is an incredibly rewarding hobby; you can see the fish and other life you look after grow and flourish thanks to your hard work and dedication. There is so much to learn about this awesome hobby, and in this guide, we will simply be running through aquarium basics for beginners. However, if you are interested in learning much more detailed information, fishkeeping tips, and fish guides, you will want to visit

Location – Where is the Best Place for Your Tank?

This is an extremely common question amongst beginner fish tank owners. Fortunately, it has a fairly easy explanation. The best place for your fish tank to reside in your house or apartment would be a quiet, less busy area, preferably away from direct sunlight and heat.

This is simply because your fish (especially when first acquired) will be a little distressed and surrounding them with loud noises and busy movement is not fair on them. This advice still applies to your fish once they are settled in. 

Also, the less natural sunlight, the better. Most fish species come from various places around the world and are used to different lighting, so often, you will have to replicate that in your tank – natural sunlight coming in will almost certainly cause more harm than good.

Aquarium Equipment

The equipment your aquarium needs is reliant on your fish and their requirements; however, most people starting out in the hobby (beginners) will be experimenting with freshwater fish, typically Goldfish. So, here is what you would need in a freshwater tank:

  • A water filter
  • Lighting
  • A water heater
  • Chlorine remover
  • Test kits
  • Substrate and decorations

So, that is the basic equipment you will need for your freshwater fish tank. However, some people that start out want saltwater fish in their beginner fish tank, so here are the equipment requirements for a saltwater tank:

  • Water filter
  • Marine fish tank lighting
  • Pumps/powerheads
  • Heater
  • Marine aquarium sump
  • Protein Skimmer
  • Saltwater tank gravel/substrate

Water Care for Your Beginner Fish Tank

Once you have got your new tank and established some of the aquarium basics, you will need to familiarize yourself with the process of water care. You should always add a solution to any water before you put it in your tank. Tetra AquaSafe Solution helps neutralize or eliminate chlorine, chloramine, and heavy metals from your aquarium water. If your first tank is a small one, it is recommended to use spring water as it doesn’t contain any harmful chemicals.

You must change 10% of your aquarium water every week at the very least, or 25% every two weeks. The water you are replacing your tank water with must be the exact same temperature. Make sure to treat tap water with a water conditioner to neutralize any chlorine and ammonia before adding it to the aquarium. You should always change your filter cartridges at least once per month.

Best Fish for a Beginner Fish Tank

Selecting the right fish for your first tank is always a tough call, sure you could play it safe and go for a Common Goldfish or perhaps one of the Rasbora species, but you might not like the look or personality of either of those fish types.

The biggest recommendation when it comes to purchasing fish to occupy your aquarium is getting the most compatible ones. You do not want to purchase two fish types that are not compatible and will spend the whole time fighting. It is strongly recommended to do your research before purchasing any two types of fish, or even multiples of one species.

Here are the best fish for a beginner fish tank:

  • Rasboras
  • Common Goldfish
  • Tetras
  • Corydoras
  • Platies
  • Betta Fish
  • Barbs
  • Bolivian Cichlids

Here are the best (and easiest) fish for a tropical fish tank:

  • Guppy
  • Molly
  • Zebra danios
  • Dwarf Gouramis
  • Bettas
  • Catfish
  • Swordtails
  • Firemouth Cichlid

Best Accessories to Make Your New Tank Awesome

Nothing is better than setting up your first aquarium, choosing the best fish for it that are also compatible with one another, and then filling it with awesome accessories and decorations! 

Some of the best decorations are simply funky aquarium boxes and caves for your fish to hide in, some people even go as far as to recreate Bikini Bottom from SpongeBob!

Some other good accessories would be colored gravel, ornaments like a volcano, underwater LED lights to give some different color to your tank, and an awesome mixture of aquarium plants.


Beginning your journey into becoming a fish tank and aquarium owner is somewhat daunting, although, if you follow this aquarium guide, running you through all the aquarium basics you need to know, you should be fine and will soon become an expert, expanding your community and aquarium life in no time!

Top 10 Beginner’s Corals for Your First Reef Aquarium

So you took the bold step of starting an all-out reef aquarium– not just a fish-only saltwater tank, but a reef aquarium with fishes, live rocks, and corals. Sounds fun, right?

However, many newbie and even experienced aquarists tend to get overwhelmed and become hesitant in adding marine corals into their tank. The primary reason is that in the past, the needs of these creatures were not fully understood and keeping them alive in an aquarium is almost impossible. 

Now that more research and products are available at your disposal, many corals are even considered easy to maintain. In this article, we’ll share the top 10 corals for first-time reefers and average hobbyists.

Preparing Your Aquarium

Before you get too excited, you have to ensure all parameters are stable and you’ve let your aquarium cycle with live rock for one to one-and-a-half months. Next, add in a clean-up crew and let them do their thing for another couple of weeks.

Once you’ve done all these steps and your aquarium is properly cycled, your tank is ready for its first inhabitants. 

The Best Corals for Beginners

For novice aquarists, fast-growing corals that are easy to maintain are recommended. Don’t know which ones fit into this category? 

With the help of Pieces of the Ocean, we’ve put together a list of cheap, easy-to-find corals that we recommend for new reef aquarium owners.

1. Mushroom Corals

Perhaps the easiest to grow in a reef aquarium are mushroom corals. They’re soft corals that come in various colors and grow on rocks. They grow fast especially under optimal conditions, which are basically low light and little water movement. 

Although safe with fish, motile invertebrates, and crustaceans, don’t place it with sessile invertebrates or next to other soft and stony corals.

2. Leather Corals

Leather corals are suitable for beginners because of their adaptability to moderate light and current conditions. They don’t have a calcified skeleton, but can sting other corals to keep them at bay– so keep a space between your corals.

Unlike mushroom corals, they like moderately turbulent water flow. They’re perfect as a centerpiece, but sometimes their tentacles may retract as they clean themselves. 

When this happens, don’t worry because the film will soon be removed with proper water flow and the tentacles will reemerge.

3. Star, Green Star, and Daisy Polyps 

Star Polyps, Green Star Polyps, and Daisy Polyps are starter corals that are cheap and easy to maintain. Their appearance may vary slightly according to the strain, but they’re all beautiful and colorful.

They can live under high- or low-level lighting and different water currents. Although they’re hardy, one thing to note is that they react negatively to iodine and aluminum oxide which are both found in some filter sponges.

4. Zoanthids

Zoanthids look like small, colorful flowers that appear in tight clusters and grow rapidly. Even though green and brown shades are the most common, they can also come in shades of red, pink, yellow, orange, blue, lavender, and gray.

They grow best under intense light, but they can also tolerate low light conditions. Also, they prefer moderate to strong current.

Be careful though, as some species have a neurotoxin called palytoxin– so always wear gloves when handling Zoanthids.

5. Finger Leather Corals and Colt Corals

As the name suggests, Finger Leather Corals resemble stubby fingers. They have a pale-colored stalk from which the finger-like projections stem upward. Finger Leather corals are recommended for beginners because they can adapt to most light and water current conditions.

However, they grow best under moderate light and current, as they’re naturally found mid-water in oceans.

6. Xenia 

One of the fastest growing soft coral is Xenia, with the most popular being the pulsing type. What’s great about this coral is that it doesn’t only sway along with the current, but also rhythmically opens and closes its tentacles.

However, because it spreads quite rapidly, it’s recommended to isolate it so you can easily prune it back.

7. Toadstool Mushroom Coral

Toadstool Mushroom Coral got its name, as it looks much like toadstool mushrooms. This type of coral grows fast and is recommended for newbie aquarists because it can easily adapt to a range of lighting conditions and low to moderate water current levels. However, take note that they can produce toxins that may adversely affect sea anemones and stony corals.

8. Euphyllia

Euphyillia is the scientific name for large polyp stony corals such as Frog Spawn, Hammer, and Torch corals. They are characterized by huge, colorful polyps that have fluorescent tips.

What makes them suitable for novices is that they can be placed anywhere in the aquarium and can adapt to various lighting and current conditions. Because they don’t grow too fast, they don’t have to be isolated or pruned back frequently.

They look good when fully extended and they sway along with the water current.

9. Closed and Dented Brain Corals

Closed Brain Coral, Pacific Cactus Coral, Brain Coral, Meat Coral, or Dented Brain Corals grow well in captivity as they’re tolerant of a wide range of light and current conditions. However, they prefer intense but indirect light and low to moderate water current.

What’s interesting about this type is that they’re reactive to food in the water and may extend their tentacles when they detect food nearby. Also, it’s important to note that they’re sensitive to some soft corals such as Xenia.

10. Bubble Corals

Bubble Corals have big, colorful polyps similar to Euphyllia. This is one of the top picks of beginners because of its unique appearance that resembles a bunch of small bubbles swaying with the current. 

They grow pretty fast, but not as fast as other corals such as mushroom and leather corals. Their colors vary, but most are white, neon green, or light pink.

Patience is the Key

Maintaining a reef aquarium is an enjoyable hobby. There’s little more relaxing and rewarding than watching your corals bring life, color, and movement to your tank. 

However, before you get to experience the good, remember that you have to go through the sometimes lengthy process of achieving a successful reef aquarium. If your tank looks like a barren garden today, just be patient as it will eventually turn into your own little underwater paradise.

They tried and tried but to no avail. The local demons caught hold of their attempts and mocked them. They even heightened the waterfall. After hundred years of constant leaping, one koi made it to the top of the waterfall.

How Many Guppies In A 10 Gallon Tank – Caring for the Fish the Right Way!

A 10-gallon tank is the most basic tank size for most homes. If you’re looking to put guppies in a 10-gallon tank, I’m sure you’re wondering how many can go in. And since guppies are beginner-friendly fish, you can buy a few of them to put in a single tank.

Guppies are easy to care for in terms of food and cleanliness. Moreover, they’re also easier to take care of during breeding. In fact, they hardly need any care at all!

If you’re planning to bring home some guppies to take care of, this is what you ought to know.

How Many Guppies Can You Put In A 10-Gallon Tank

Based on the size considerations, a 10-gallon tank does not necessarily hold 10 gallons of water. Because of the extra things such as the gravel, filter, heater, sponge, etc. some space will reduce.

This shouldn’t be more than a few gallons of water worth of space. So in a 10-gallon tank, once it is set up, you can put up to 7-8 guppies.

A single guppy occupies 1 gallon of water as a general rule of thumb. Based on this calculation, a 10-gallon water tank can 7 to 8 adult guppies.

But before you add the guppies to the tank, always make sure you set up the aquarium first. Start with gravel, water filter, sponge filter, and heater if required. Then decorate the tank a bit with live plants, tunnels, and other decorative toys.

These things take up 3-4 gallons of water volume which means your 10-gallon tank has a 6-7 gallon water capacity for the fish to live in. That is why it’s essential to stick to the “1 guppy per gallon” rule!

Male or Female Guppies

There are multiple ways to go about this. While the best companions for guppies are more guppies. Deciding between male and female guppies, male guppies are more popular as they have a more vivid and beautiful appearance.

The vibrant colors of the male guppies will brighten up any fish tank – no matter the size. If you’re buying all male guppies, it’s best to reduce the number of guppies per fish tank.

So in a 10-gallon tank, do not keep more than 5 male guppies together.

If you plan on keeping male and female guppies together, maintain a 2:1 ratio. So for every 2 female guppies, keep 1 male guppy. Most likely, you’re setting up a breeding tank so you have to get ready for fry. This begs the next question:

Can I Breed Guppies In A 10-Gallon Tank?

It’s true that guppies breed uncontrollably. And an adult female guppy can experience multiple pregnancies over a period of time. This can happen at any time so you must be very careful.

You will need a separate fish tank to put the fry in after. Because the mother guppy will eat them if you do not remove either the female fish from the tank after birthing or separate the guppies. The baby guppies reach sexual maturity by the age of 3-5 months.

Female guppies tend to get stressed when you keep them in a small breeding trap during birthing. So make sure you invest in a spacious breeding trap and keep live plants on the bottom for the fry to hide during the initial stages.

It’s perfectly okay to allow a male guppy to fertilize the female guppy for breeding in a 10-gallon tank. But guppies are prone to eat the live young (fry) soon after birthing. So invest in a comfortable and large fish tank for breeding is necessary.

How to Care for Guppies In A 10-Gallon Tank

Like I said earlier, guppies are really simple and easy to take care of. However, if you buy a lot of guppies at once, they can become quite a handful.

But make sure you maintain the following things to keep your guppies well-fed and disease-free.

The ideal habitat for guppies is a freshwater environment. They need heated water up to 75 to 82-degrees Fahrenheit. Since guppies are low-maintenance fish, it’s easier to maintain a calm and comforting environment for your guppy. 

The more guppies you have, the faster the fish tank’s water quality will deteriorate. That is why it’s necessary to buy a water filter to keep the water quality normal. Invest in a sponge filter as well to accelerate the water-filtering process.

Regardless of how many water filters you install in the fish tank, water changes are necessary. Rinse the tank, the decorative items, and add fresh water to the tank.

For good, guppy food is available in most pet stores. You can also give them fish flakes, frozen shrimp, and live foods from time to time. Some guppies also enjoy eating fresh veggies like cucumbers, lettuce, and peas.

The ideal feeding time for guppies is 2 times per day. Never overfeed your guppies during each meal. If you notice that the water tank gets dirtier quicker with food particles, this means you’re feeding them more than they need. So try reducing their food intake.


There are two types of fish tanks to keep guppies in. One is for breeding guppies and the other as a show tank. A show tank is where you keep decorative plants. If you want guppies to care for, a show tank is an ideal choice for you. But if you’re looking forward to taking care of adult guppies and their live young, a breeding tank is also essential.

Guppies are colorful, vibrant, and attractive fish. And the major advantage of having them in your tank is that they’re easy to take care of. So if you’re purchasing a 10-gallon tank to keep guppies in, add no more than 7 adult guppies.
