Are there any other fish you can keep in a 3 gallon tank?

[BettaPirate]

I am hoping to upgrade to a split 5 or 10 gallon tank for my current betta and a possibly distant future betta but will have a 3 gallon tank being unused, in n addition to the hospital tank I already have. I am just curious if there are any other fish that can live in that size tank?

I'd say shrimp would be your best bet! Most other small fish need to live in groups, and thus would need a larger tank.

thanks for the advice, I don't really like shrimp so I guess I'll just keep a betta in it and get two new betta :)

If you want it cold water Everglades Pygmy Sunfish.

These fish may be harder to find depending on where you shop. But sparkling gourami, clown killifish and dario dario are a couple of species that would do fine in a three gallon tank.

However, they can be quite sensitive to water quality so you would need to have a cycled and established tank before introducing them. Or one that has a lot of fast growing plants to act as your filter.
