:help:I don't know what to do!!!! Uriel, my angelfish, is swimming weirdly, what's wrong with him? He has a nip mark on his dorsal fin, could it be that? Or is it a swim bladder problem? Is there anyway to fix this? I think salt might help, but I can't add it since the tank has an elephant nose in it and I don't have a quarantine tank!:wall:
