How Many Neon Tetras Can You Put In A 5 Gallon Fish Tank?

Neon Tetras are a wonderful beginner fish. They stay small, only growing to about 1.5 inches as an adult. They are also very easy to care for no matter your experience level. Neon Tetras are a beautiful addition to any tropical tank and are a very inexpensive option. Tetras are also a shoaling fish, which means that they are more comfortable in large groups. Tetras ideally should be in groups of no less than 8. However, there are exceptions.

Following a common fishkeeping rule, you can typically have about 1 inch of fish per gallon and have a healthy tank. Therefore you can have about 4 to 5 adult neon tetras in a 5 gallon tank.

What Is The Ideal Tank Size For Neon Tetras

Since neon tetras are a shoaling fish, you should always plan your tank to be able to hold a group large enough for them to be comfortable. A relaxed fish = a healthy fish. The recommended minimum amount of neon tetras in a group is 8. Therefore, I would strongly recommend putting neon tetras in a tank no less than 10 or 20 gallons. They are a very active fish and like to swim all over their tanks, so the more room they have, the better.
