I am now going through a ich outbreak in my 150 gal reef tank. All seem to be doing better except for the emperor. He is an adult at about 6 or 7 inches that is still eating, but is splotchy and stands on his head when the lights go out. He seems to be hiding more during the day than normal, have treated the tank with kick-ich. Really hate to lose this beautiful fish, and would appreciate any suggestions or comments from anyone that has seen this before.
