Ha ha 39 where close. Its funny, i got ich in my tank from a snail bag that slipped into the water while acclimating. I left the tank fallow for 2 months. I lost fish in the process, so after the 2 months i was looking at fish again. My wife wanted to surprise me and asked if i wanted a new fish. I asked what they had. One was a yellow tang. I said a TANG!!!. she took that as thats what i wanted lol. I said well , we shall see if the ich is gone or not. 3 yrs later he's going strong. Tangs are a fav fish of mine. Just hippos always have the ich magnet moniker or hlle issues
