5 Gallon Vs 10-Gallon Fish Tank: Which is Better?

When choosing a tank for your fish, you should always think about the size of the tank that best suits your pets.

There are many sizes that are available for fish tanks, but in this article, we chose only two: the 5 gallon and the 10-gallon fish tank. Although the 10-gallon fish tank is a better pick majority of the time, there are pros and cons for either tank.

In this article, we’re going to help you pick what tank size is best for your fish.

Is 5 gallon fish tank too small?

The 5-gallon fish tank is the smallest that you can pick for your fish. If you’re going to pick a smaller sized tank, you’ll face some difficulties in maintaining that small of a tank. Your fish is also going to have a difficult time in the tank since they have no room to swim. 

The 5-gallon tank is small enough to fit a desk or a table so it is perfect for small apartments. It may be small, but it’s enough for small fishes like bettas to swim in. However, it is not recommended for schooling fish since they do thrive better in bigger groups. Unfortunately, the maximum number of fish that you can put in a 5-gallon tank is 4-5 fish, which isn’t enough for many schooling fish species.

What fish live well in a 5-gallon tank?

Fishes that like to be alone are good for 5-gallon tanks. Since they’re the sole resident of the tank, it still leaves them plenty of room to swim.

Betta fish, like the spadetail betta, are a prime example of fish that are the best fit for the 5-gallon tanks. They’re beautiful, intelligent, and have unique personalities, so a 5-gallon tank is a great way to showcase them. They also tend to be low-maintenance, at least compared to bigger community tanks.

Guppies can also be a good choice for 5-gallon tanks. You can fit 4 to 5 guppies in the tank and watch them swim around and munch on their food. Guppies are much more energetic than bettas, so if you want a fish that swims all day, you can consider guppies. 

How many fish can a 5-gallon tank support?

It depends on what fish you’re going to put in the 5-gallon tank. As mentioned above, there are some fish species that enjoy being alone, while there are also fish who want companions or are part of a school.

When you’re choosing betta fish for the tank, you can only put one fish in the tank. Betta fish are territorial, so when you’re putting them together in a small tank, they fight and might lead to them being injured or worse – dead.

Guppies, on the other hand, can coexist with one another. You can put 4 to 5 guppies in the 5-gallon tank and look at them swimming with energy. You can put up to 5 fish in the tank if the fish is a schooling fish that can coexist with another fish in the tank. 

Is 10-gallon enough for a betta?

Bettas ca actually live even in a 5-gallon tank, although 10 gallons is still much better for them.

In fact, a 10-gallon tank is perfect for bettas, giving them sufficient space to swim around in the tank. Bettas are naturally territorial, so a larger tank that can provide them enough space they can call their own is a good thing.

A larger tank is also better for bottom feeder tank mates since the betta will just ignore them. You can try other tank mates by trying to put them with the betta, but if they attack, they’re probably not a safe choice. 

We now know that a 10 gallon is perfect for bettas, but you also need to know that just having a big space for the tank is not enough. You have to make sure that the tank is in perfect condition to house a betta fish.

How many fish can go in a 10-gallon tank?

Aquarists say you can put 1 fish per gallon in a tank, so you can put 10 fish in a 10-gallon tank. This will depend on the fish, of course. If you want a betta fish you should aim at least 1 for the 10-gallon tank to avoid fighting.

If you’re a honed aquarist and you can keep your tank for a great living condition for the fish, you can now put 2 small fishes per gallon in the tank. 

How many fish can go in a 5-gallon tank?

Same as stated above you can put 1 fish per gallon in a tank but for a 5-gallon tank it should not be more than 5. Having more than the 5 fish limit in the tank can affect its quality. A 5-gallon tank is a small tank, and the oxygen level is only enough for 5 fish.

If you continue to cramp more than 5 fish in a 5-gallon tank, your fish can also die from ammonia poisoning. You should be observant of the conditions of your tank so that you can ensure that it remains a comfortable home for your pet fish.
