I have a ocellaris clown in my tank since the beginning early Feb 2010, she is about 1.5 inches. For the past 48 hours she has stopped traveling the tank and hovers in mostly one area near the bottom, strong water flow area, and is breathing heavily and not eating. Her smaller mate is doing fine roaming the tank and eating well as well as the other fish. I offer both frozen mysis and variety food as well as flake she has always eaten both. I can not see any spots on her but thought there might be a few fuzzy areas starting (velvet?), even if I was to photo her I don't believe you could see anything. This evening she had a strand of I believe poo hanging from her anus area but it was white like is mentioned in some disease. All fish I have added have done fine except I lost a Coral Angel I believe due to eating problems. My latest addition was my Med. Blue Hippo Tang which I believe my have introduced ich to my tank. He appeared fine so I added him to my tank without QT about 2-weeks ago (Live & Learn) within a few days I seen a few spots. I removed him and left him in QT 3 days past the spots being gone (8 days). he has been back in the tank for 1 week. Any Ideas on what is going on with my Clown. I would hate to lose her as she was one of my first two fish.. My current action was tonight 3/22 I gave her a freshwater dip, very stressful ordeal for a new aquarist, and I placed her in a 5 gal QT tank with a copper based medicine. I do have crushed coral in the QT tank w/ heater and hangover filter. I have since read I should remove the substrate in the tank, but I want to let her settle and not stress her or me more this evening.
