How many tetras can go in a 2 gallon fish tank?
It can be difficult to determine how many tetras a tank can hold. Tetras are schooling fish, meaning they like being in groups of five or more. Some experts say you should start with one male and four females for every two gallons of water, but this is only an estimation that will vary based on the size and species of your fish.
A gallon of water is about eight liters, so a 2 gallon fish tank worth of water can usually support five or six tetras if they are all small fish and three to four tetras when they are larger. Tetra species such as cories might be able to live in the same size tank because they prefer living alone.
