How many fish can you fit into a 2-gallon fish tank?

Answer by  critesb1 (224)

Depending on the size of your fish. There could be anywhere between two and three small ones. With bigger fish only one or two. For they need to have room in the tank to swim without hitting each other or the glass. Also need room to grow into their surrounding.

I have always used the rule of thumb that you can have roughly one inch of fish per gallon of water in the bowl or aquarium.
