I have a pangasius catfish, had him for about 3 years now, my wife noticed that one of his eye's was glazed over and his fins seem to be a little jagged, as if they have been nipped on. Never noticed any other fish nipping anything in the tank. The "glazed eye" is white and there are a couple of places on his body, though very small, that it looks as if the skin were pealing off. We thought it might be ich, but havent seen any signs on any of the other fish in the tank. All water params are good, 100gal running about 4 years now. Havent had any issues in a long time, I guess it might be our time again, hope not. Any ideas on what this might be would be great, any treatments we could do that "wouldn't hurt and might help" would be great too. Thanks in advance for your info and time.
