One of mine died from ich (I hope both your percs make it). The other one survived, just like the chromis and blenny. I have not added any fish to my reef tank for a few weeks now, and won't for a few more just in case. The life cycle of ich is about 45 to 60 days, I hope the remaining fish is immune by now.
The only question that I have is...if I add more fish in let's say 90 days, will the ich come back and doom the new fish? I do regular water changes, the tank looks good, but will the ich stay to haunt me in the future?
Many thanks.
