My daughter wants some fish, so my daughter is going to get some fish. Got a small tank laying around in the closet, it must be about a five gallon, I'd love to use that rather than going out an buying another tank if I can help it. What freshwater fish or animal can I get that will stay small enough to enjoy that? I'd like it to be something that can be housed with a few of eachother. I suppose if I had to bump up to a ten gallon I could compromise. We had gold fish at one point that used to let her pet them, but they were soley bought as food for my gator so she misses fish now. ideas?
