If you look around really hard you can find a variety of fish you can keep in a 2.5 gallon tank. Many, many killifish will do well in that size tank as a pair, croaking gourami, sparkling gourami, guppies, least killifish (actually a live bearer) pygmy cory cats... just to name a few. All of those should do great as a pair in a 2.5 gallon tank.

Depending on the kind of fish you want or have. It depends because fish grow and you have to find out how big they will get later.
2.5 gallons isn't really big. I want to say 1 fish. I would find a book about fish and read up. If you want more than 1 fish..get a bigger tank. You don't want to crowd the fish.

the only fish that could possibly thrive in a 2.5 gal tank is a fancy betta really, that's it. i personally won't keep a betta in anything less than 4 or 5 gal.
2.5 is tiny, and pretty much every other fish out there is too active for such a tiny tank. fish need space!
maybe turn the 2.5 into a flower vase and buy a larger tank hehe.

The rule is that for every gallon you can have an inch of fish. So if you get a fish that grows to 2-3 inchs then only one. But if you get fish that grow up to an inch you could probly get away with 3 but I would stick with 2.
