What To Look For In A 10-Gallon Fish Tank

When you’re picking out your tank, there are a few things to consider to make sure you’re getting the right tank for you.

Here are some things to bear in mind when choosing your fish tank.


The dimensions of a fish tank can vary, even if they hold the same capacity of water.

Depending on the dimensions of the tank you might find it difficult to find a good place to keep it.

You also need to factor in other parts of the tank, such as the lid and any equipment, that might make the tank inconvenient to store.

Additionally, your fish should be given a good amount of space in all directions.

If your tank is too short or narrow, your fish might not be able to move around as much as they need to.

Most fish also need a hide or shelter that they can go into, as spending too much time directly in sight or under the lights of the tank can be distressing for your fish.

If the tank is too small for an appropriate shelter it can cause your fish a lot of stress.


The shape of the aquarium can also be a factor.

While most fish tanks (especially small, 10-gallon tanks) are a traditional rectangle, some tanks like the Fluval Flex and the Penn-Plax Curved Corner tank, have curved sides that are a departure from the norm.

Not only do these give you better visibility of the inside of the tank, but it also means that the water currents inside your fish tank are able to flow better.

You should never get a bowl-shaped tank for your fish.

These have poor filtration and often lead to a buildup of CO2 and harmful chemicals that are harmful to your fish.

Equipment Included

A lot of kits, included many on this list, come with everything you need to set up your tank.

However, this isn’t always the case; tanks like the Penn-Plax Curved Glass and the All Glass aquarium kit don’t provide everything your tank needs such as a heater or water filter.

This can be an issue as finding the suitable equipment for your tank can be difficult, and finding and purchasing the right equipment separately can be frustrating.

If you’re a beginner looking for their first tank, finding a tank with everything you need already included (such as the Aqueon Aquarium or GloFish starter kits) might be the better choice, as you’ll have everything you need without the hassle of finding compatible equipment separately.

Frequently Asked Questions

How Many Fish Can I Keep In A 10-Gallon Tank?

As a general rule of thumb, your tank should contain 1 gallon of water for every inch of fish you’ll be housing.

Using this guideline, you can easily house multiple small fish in a single tank.

That said, don’t think that housing 10 small fish in a single tank will work out.

Even if you stick to the rule of a gallon per inch, keeping lots of fish in one tank is an easy way to leave your fish cramped for space, especially if you don’t factor in the space taken up by lights, the filter, and other equipment in the tank itself.

Additionally, some species of fish require more space to live comfortably, and there are even species that need to be housed individually.

This could be due to the fish being territorial, if they grow in size, or simply just because they enjoy having more room.

If you’re keeping small fish such as tetras or guppies, you should only keep a maximum of 4-5 in a 10-gallon tank.

For larger and/or more territorial species, one or two fish should be the limit.

What Does My Fish Tank Need?

Depending on the species of fish you’re keeping in your tank, you might need some specialist kit for your fish tank.

However, there are some things that are absolutely necessary to include in your aquarium.

Your tank will need to include lights, a filter, substrate, and some decorations for your fish to hide behind or under.

Most fish will also need a heater; tropical fish in particular need to be kept in warmer water, and many freshwater fish will also need to have the water above an ambient temperature.

You should always check what conditions and requirements your fish need in their tank, making sure that you know exactly what you should be including based on the species you’ll be housing.

How Do You Maintain A Fish Tank?

After your tank is fully set up and cycled and you’ve introduced your fish, you need to make sure you take good care of the tank.

If you don’t maintain your tank regularly, your fish can become sick or even die.

You should check the pH of the water in your tank on a regular basis, as even a small change in the acidity can have disastrous effects on your fish’s health.

Most aquarium test kits will have ways to monitor the pH of your tank, so you can keep a close eye on the conditions inside the tank.

Temperature is also important to monitor, so you should use a thermometer to ensure that the temperature within the tank is appropriate for your fish.

Another thing you need to keep an eye on is the waste inside your tank.

Just like any other animal, your fish will produce waste. Over time, this can build up and affect the water quality.

If you notice the water in your fish tank becoming cloudy, or if there is visible waste floating around, you need to give your tank a clean.
