Hello all. I have a clown fish for about 3 months that has a white spot on it's side and under it's fin. My main tank developed ick so I moved everyone to a QT for over a month. I teated them for over a month with Sea Cure Copper, Copper Safe, Maracyn 1 & 2 and Maroxy. Also did fresh water formalin dips. I scraped it off with a knife once and it looked good for about 2 weeks but it appears to be coming back. Any ideas what this maybe? I think I used all the medicines possible!!! I'm afraid to move him back to the main tank until this is all cleared up.
