Anyone else have a repeat offender that keeps getting ich? He (blue hippo tang) gets over it everytime but any little change in the tank causes him stress and he gets ich often. He and my angel fish (flame angel) get it and fight it off but they are big eaters too. I treat their food with Selcon and sometimes garlic. They are healthy but itchy little fish. The rest of the tank never really show signs. My yellow tang is spotless but I always see my cleaner wrasse cleaning her too. I am not gonna empty all fish from the tank so I just try to help build their immunity so they can fight it! Anyone else have this issue? What do you do to try to help with this?
