Okay so my tank I've had Ick in it for awhile. I haven't lost a single fish to Ick but usually at night I see a few specks of it on my clown tang, saw tail tangs, and yellow tang. None on the kole, fairy wrasses, Midas blenny, and foxface. I was wondering, besides taking out all the fish what's the best way to control it in a reef tank. It's a mixed reef so most medications will kill coral
