Don't know if anybody has seen this before but I am surprised. When I've had ick in a tank pretty much everyone shows signs of it. When I got back from vacation one severum looks like he has been well salted. Pretty sure it's ick, seen it enough times. Started the heat and salt treatment immediately. He is not showing signs of getting better or worse. Swims around and eats just fine. That was on Monday. No one else in the tank has so much as a single speck. Anyone had this happen? Any ideas?
