About a week ago my black clown started showing signs of popeye at the same time a blue tail damsel did also. I have been treating the tank with Piramfix (antifungal) and Melafix (antibacterial). I have treated the tank for 4 days now and the damsels infection has cleared up, the black clowns only seems to get worse. Is there anything else that I can do or treat him with? Thanks
