I came home last night and there's a new 3"-4" oranda in my tank, apparently my girlfriends mom just bought one on a whim(from petsmart no less) and put it in the tank. It has some white stuff on the back of its wen, its not ich but I fear may be some kind of fungus, but it could also be coloration maybe? here are some photos (bad ones at that) hopefully it can be clear enough for you guys to diagnose.
