We recently bought a silver dollar and tinfoil barb, and they were the best of friends. They were very small when we got them and unfortunatly our clawed frog got the best of the barb. Now our silverdollar is lonely, is getting one more a good thing to do? I'd rather not have a bunch, since I already have black finned sharks and other fishes taking up space in the 55g.
Another question is we got some fish from a relative, one being a giant danio, he is very aggressive, specially towards the silver dollar and blind cavefish and wont let them on "his" side of the tank. I do not know if the danio is male or female, but what I do know, that I just noticed recently, is towards the night time, he gets a beautiful redish/orange color lining his stomach all the way to his tail, but it goes away during the day, what is this? Actually I dont even think it goes all the way down his stomach, I think it starts half way, by the anal fin? By the way, the silver dollar is bigger than the giant danio, yet, he still gets picked on. I have a friend that works at the only petstore here, and has never seen nor heard of a giant danio, so getting him a mate would be out of the question unless I wanted to drive a ways.
