I had ich in my tank, 55 gallon.
Kohl tang was 1st infected and covered in it. Before I realized, had gotten a maroon clown. He had been quarantined for over 2 wks, and when I put him in the big tank, he got mucus all over him. He didn't eat for 3 days, and I treated the tank with quICK cure. He cleared up and is eating fine now. But this morning, I tturned the lights on and noticed ich returning, and the powder brown tang is scratching on the bottom and seems to have brown spots all over him.
Clown is getting mucous again, and my kohl tangs color is VERY light. Have green chromis and they seem to be alright-though one has a few white spots on tailfin. We've also been running a Magnum 350 for extra cleaning, that we borrowed from the fish store(definitely investing in one of those!!) I read something about black ich-I'm at a loss-any help out there?
