actually they were never in my display tank when they got sick. Ok here is what happened. My
royal gramma had a mild case of itch, so i decided to take all the fish out of my display. Well after 4 weeks all seemed good in the quarantine. It looked like i didnt have itch anymore, but i have got to admit that i did let the water quality in the quarantine tank slide a little (big mistake i know) well looks like the clowns have itch so i will have to go through the process all over again. But this time i changed all the water in the quarantine, washed it reall good, washed all the equipment and started over with some already mixed saltwater. It looks like very little itch, just enough for you to get worried. My display has been empty for 4 weeks now.
