Hello all, I have an extra 2.5 gallon tank lying around after I upgraded to a larger tank. I do not think that I want another betta, as I have 2 already and I was wondering what kind of animals can go in it. I know it is too small for other fish, but are there shrimp or frogs that can live happily in it? Or can I make a small, all plant tank? Any answers would be greatly appreciated.
