Very true but ick is brought on by stress to the fish, copper treating a fish just makes it worse and especially with tangs they stress so easily, the ick has already invaded the aquarium it's going to be near impossible to get rid of it without starting over, I personally have ick in my mixed reef but my fish aren't stressed so it doesn't bother them at allThis is why we quarantine everything...coral, inverts, fish....you can keep ich out of a system if you do so..
