I'm new to fish, and planning to get a fish or two soon. I'm trying to find a fish who can be alone or in a small group. I can't handle a large group because I won't have a very big tank at first, but I want to have a fish who could have a friend or two in there. I'll probably have about a 2-3 gallon tank for a while, and try to find a larger one when I can. I will have a 10 gallon limit for a few years though.
I like bettas, but can they be in groups with other fish? Would a female betta accept other fish better? I was thinking of cory catfish as companions or instead of a betta, but I don't know if I can find them here. Do they need a larger tank? Any other suggestions if these don't sound like the right fish? I'm looking for one without really special care since I'm new.
