I bought two clows last week, and one of them it looks like is starting to mate with the clown I already had in the tank, and the other is not doing so good. I watch the clowns and they chase the one away thats by himself, and I looked at him today, and one of his fins is stuck to his body, and I have a yellow clown goby and he's got some bright little yellow spots on his fiyns. Anyone know what I could do to treat these fish. Thanks,
