I'd use it as a hospital tank, and if you already have one I'd use it for a very mini freshwater trop tank. I don't think it's big enough for rodents or reptiles.
Maybe you could do a couple dwarf frogs and a half dozen cory's or something. With a good filter I'm sure it would be fine! Maybe a really planted tank?
I wouldn't keep half a dozen cories in a 10g unless it was a low and long tank, and the cories were very small. I have 7 bronze cories in a 34g and the room at the bottom seems just right, even with all that space.
I find it really difficult to suggest fish that would work well in a community tank that small... Maybe one of the small gouramis, like dwarf or honey?
