Please can anyone help? I have an established tank with a plec, 2 praecox, 2 dwarf pangasus catfish, 4 serpae, some cardinals and a molly. My molly has one popping out eye. My book suggests injury as only one eye is affected and the other fish are fine. I'm new to internet, but the few sites I've braved have suggested Melafix. Do you agree, and is it safe for all my other fish? I do not have a spare hospital tank and am terrified of harming the other fish, especially my plec, as he is my mate! Many thanks. Saraya. x
