Well I didn't t quarantine a fish long enough and now have ick in the display tank. Only one fish is showing it but I know they all have it. I'm going to do the tank transfer technique for the fish and let the display be fallow for the 9 weeks. My question is, I' d like more corals down the road and realize they could bring ick back into display tank, so how is everyone handling the corals? Do you need to keep them in an isolated tank for 9 weeks, with the same lighting as display tank?
