A ten-gallon aquarium is an affordable choice for anyone who wants to keep a small community tank, single species tank, or shrimp tank. Though a ten-gallon tank may be small, it is still vital to stay on top of maintenance as the smaller the water volume in the tank means it is more susceptible to fluctuations in water parameters.

Hagen 15004HG Fluval Flex aquarium 9-gallon

The Fluval Flex is a lovely little aquarium that makes for an ideal starter tank. The shape is designed to give a curve at the front, which allows for an amazing viewing window to watch your fish within and also gives the appearance of a larger tank.

The LED lamp hidden under the lid includes 36 white and 3 RGB LEDs and is adjustable with the remote control. The lighting itself features numerous settings and is suited for livestock and plants.

Back panel filtration systemBack panel filtration system #ad

The filtration system is tucked away at the back in order not to spoil the view of the main tank. The back filtration panel comes with 3 compartments for housing a return pump and filter media, which are also included. This is also a great place for a nano skimmer (not included) if you want to set up the tank as a nano reef.

Overall; this is definitely high up on our list for a 10-gallon tank, especially if being bought by/for a beginner. You will only need to buy a 50W heater and you can keep tropical fish in the tank. Some people set it as a nano reef and the complete tanks look stunning through the curved-front glass.

Penn Plax curved corner glass aquarium kit

This 10-gallon aquarium is a little different than the others on our list, it is both frameless and curved. The benefit of this is you gain a larger viewing area from any around angles and it creates the illusion of a much larger tank.

Cascade 300 internal filterCascade 300 internal filter #ad

The kit comes with a Cascade 300 internal filter, LED light, mat, and hinged plastic lid. This is ready to go if you intend on keeping cold-water fish, or you can add a small heater and change this to tropical.

It’s incredibly easy to set up so this is highly recommended for those that lack confidence in setting an aquarium up.

Penn Plax Water World Vertex desktop aquarium kit

The Vertex tank is specially designed to fit in small spaces, so this makes the perfect choice if you’re looking for a desktop tank. It is frameless and has curved corners at the front, making for a smooth finish.

It doesn’t come with a light rail, however, thanks to its transparent lid, you can easily use a clip-on LED light on the tank. You can also choose a light fixture with extendable brackets from 12-16 inches to fit the length of the tank.

If you’re looking for a tank that’s differently shaped than most then this is definitely one to consider!

The filtration system makes it ideal to set up a nano reef with the tank because it provides a great place to hide many necessary accessories. As you know, reef setups need more equipment than freshwater ones. You certainly need a specific LED light if you want to keep corals in the tank.

The last aquarium on our list is a little larger at 12-gallons but is such a striking one that you should definitely consider this. It is an incredible shape and has a hidden LED lighting system that offers tremendous lighting for a small tank.

A lid is necessary to decrease the evaporation of the aquarium water, keep the temperature stable, and prevent some fish from jumping out of the water. If your tank does not include a lid, ensure you measure up your tank correctly and check against the dimensions of the lid you intend to buy.

Stand

The majority of 10-gallon aquariums will not come with a stand and it is always best to use a stand that is designed for aquariums, as these are made to be able to take the weight of a filled tank. It may not be as vital with a 10-gallon tank, you may have a sturdy unit or bench you can hold this on but it is usually better to be safe.

To select a stand that will fit your new aquarium simply check that the length and width of the tank itself match the stand and that it can bear the total weight of the tank filled with water.

Lighting

Aquariums usually come with their own form of lighting but if yours does not, or you wish to use a different type or strength of lighting unit then it’s not usually a difficult thing to change.

For a 10-gallon tank, you can choose a clip-on LED light or a 20-inch fixture. Always remember to ensure that the light is suitable for the length of your tank and whether it is suited to the plants/ livestock kept within.

Most LED lights from aquarium kits are white light, some include blue moonlight. They are usually just enough for viewing fish and support some low light plants such as Marimo moss balls, Anubias, ferns, and moss. If you intend for a high demanding planted tank, change to a more suitable light.

Filter

Filtration is vital to get correct within any aquarium! A good filtration system will keep your water in tip-top condition and reduce the chance of death and illness within your tank.

When searching for a new filter, you should opt for one that is capable of turning over the volume of water in your tank 4 times per hour. That means in a 10-gallon aquarium you need one that turns over 40 GPH (gallons per hour).

Choose your filter heater: https://portlandaquarium.net/aquarium-filter/

Heater

Orlushy Mini Aquarium Heater 50WOrlushy Mini Aquarium Heater 50W #ad

A heater is needed if keeping tropical fish, this isn’t always an item that comes as standard when purchasing a tank. If you’d like to add one to your aquarium then you need to select one that is matched to your tank size and can hold the temperature required, based on the fish you keep.

As a general rule 1W (Watt) is required per liter of water, so for a 10-gallon tank, we’d advise a heater that is at least 40 Watts. Because there is no 40-watt heater being manufactured, a 50-watt heater perfectly suits the tank.

Choose a heater here: https://portlandaquarium.net/fish-tank-heater/

Substrate

Spectrastone Shallow Creek RegularSpectrastone Shallow Creek Regular #ad

A pound per gallon is a good rule-of-thumb to have a 1-inch substrate. This means you will need at least 10 pounds of substrate for a 10-gallon tank.

For fish-only tanks, the substrate thickness depends on your preferences but ensure it is not too thin. Just go with medium-sized gravels for easy cleaning.

You will need a planted aquarium substrate if you intend to have live plants within the tank. Planted tanks will need a 2-3 inch substrate for plant roots to develop, too.

Background

Vepotek aquarium background, double sides for choiceVepotek aquarium background, double sides for choice #ad

An aquarium background is certainly an optional accessory but this can be a fun way to snazz up your tank or to make it more natural for the fish/animals kept within.

When choosing a background simply measure the total length and height of the tank and match it to the background you’d like. If you’re not certain of the exact size required then buy a little larger as you can usually trim them to size very easily.

Air Pump

Tetra Whisper Air Pump for up to 10 gallonsTetra Whisper Air Pump for up to 10 gallons #ad

An air pump is an optional extra in any tank, but one we would recommend having as it provides a few benefits. It creates agitation of the water surface and provides extra oxygen to the water, which is needed by everything living within. It is also used to power some kinds of filters and decorations as well.

For a 10-Gallon aquarium, you need one that has a minimum output of 0.330 liters/min. This number varies based on how much equipment being powered with the air pump and how deep your tank is.

If you keep a saltwater/marine aquarium then you will need to locate a slightly stronger one, as saltwater has less oxygen solubility than freshwater.

Water Pump

A water pump is of great benefit to an aquarium if you wish to create a natural flow of water within the aquarium. This helps to keep water fresh and provides fish with a current, which some prefer to play/swim in. The extra benefit is that a water pump can also be used to assist with water changes.

When picking a water pump, you should get one that rotates the volume of water in your tank 5 times per hour. This means for a 10-gallon tank you’d need a minimum rate of 50 GPH to ensure the best efficiency.

Decoration

The options are endless when it comes to an aquarium. You can have ornamental décor; from skulls, ships, chests, etc. to plants, wood, caves. The only restriction is size, due to 10-gallon tanks having limited space. You should also try to ensure your décor matches your fish’s needs, in terms of cover, hiding spots, etc.

For setting up the tank, check our guide for setting up a freshwater aquarium.

How many fish can I keep in 10 gallons?

Green-Neon-Rasbora.jpg

The amount of fish you can keep, in any aquarium, comes down to the volume of water the tank holds and the size of the fish when fully grown. Follow the rule ‘1 inch of fish per gallon of water’, you can keep a total of 10 inches of fish in a 10-gallon tank. For example, you can keep 10 fish that maxes at 1 inch when fully grown.

When choosing fish for an aquarium, ensure you choose species that have similar living conditions so that you can set up an aquarium with the best water parameters (temperature, pH, hardness, e.g.) for all of them.

Setup ideas for a 10-gallon aquarium

There are numerous options when it comes to setting up your tank and it is best to think about the outcome you’d like for your tank before starting to move things around.

Aquascaping is the art of using items within your aquariums, such as rocks, stones, wood, and plants, to create a landscape. There are a few common styles and we’ll cover some options for you.

Planted aquarium

If you have a planted aquarium then it is best to use the plants within and sculpt a natural aquascape. You can add rocks and wood, that you can plant on, and moss, etc. to create a stunning all-natural feeling within the tank.

How many plants can you keep in your 10-gallon tank? It’s nice and simple – you can keep as many plants as you can get in there as long as you leave some room for fish to swim around and have the correct lighting to care for the plants. Plants do require care, so too many can eat into your time and maintenance.

Fish-only aquarium

If you really don’t want greenery in your tank then you can create a scape using rock and wood. You can stack, build, and bury to create depth and texture. If you have ornamental decorations then use these also, tie everything in to create a visual work of art.

The key is matching your aquascaping to the fish you hold within. If you keep livebearers, provide lots of plants and cover for newborn babies to hide in to give them a chance of survival. If you keep loaches, they prefer caves and rocks.

Species-only tank

This kind of aquariums is for some species that are not suitable for community aquariums. They could be very timid or aggressive to keep with other species. They include Bettas, Gourami, Puffers, Dwarf Cichlids, Killies, Crabs, and Crayfish.

Shrimp tank

You can keep up to 50 shrimp in a 10-gallon tank. Shrimp do require space for them to hide in so the best option for aquascaping a shrimp tank will include natural or decorative caves, wood, and plants that allow for cover for the shrimp. Use the materials you have to hand to create natural caves, nooks, and crannies for them which then appear to be part of the landscape for a striking look.

Coldwater tank (unheated)

There are so many species that you can choose for a 10-gallon coldwater tank. Following are some options:

To aquascape a cold-water tank you will need to use materials like wood, stone, ornaments as plants do not tend to do well without warmth. You can build up monuments and structures, bridges, and caves to create scenery that looks natural and realistic. Use different colors and textures to create the best scape.

Saltwater fish-only with live rock (FOWLR)

If you prefer to keep saltwater fish then there are several species you could keep in the nano saltwater tank. You can use live rock or decorations to make structures and natural-forming cave systems for your fish. Live rock is relatively easy to move around and to stack, making it an ideal choice to scape with.

Reef aquarium

You have so many options with a reef aquarium! Think of how a reef appears out in the oceans and try to recreate it in an aesthetically pleasing way. Use colors and shapes to make a natural-looking reef formation. Scatter things and make it look random, as it would in the wild.

Some hardy soft and LPS corals can thrive in such a nano reef tank. A small LED reef light unit perfectly fits the needs of a small reef. SPS corals are not suitable for small tanks as they are harder to care for and require stable aquarium conditions to survive.
