So i noticed 9 days ago my Blue Hippo Tang had developed some ich spots overnight. The next day he had what looked like pop-eye to me. I went to my LFS and they advised me to use Pimaflex instead of taking the Blue Tang out and quarentine him. Since then the Blue Tang has gotten a little better and my 4 of my 5 other tangs (Tominari, Powder Brown, Sailfin, Kole) which were all ok before and during treatment have just up and died all a day apart after the 7 day Pimaflex treatment. All I have left are a Yellow Tang my Blue hippo (which still has ich episodes every other day which seems to be kept in check by my cleaner shrimp) and a couple damsels and clowns. Im willing to do whatever it takes to rectify this obviously wrong advice i was given. Also all my corals are doing fine except for my cauliflower colt coral. Its normally 23" across and now its all shrunk up like a softball. Could the Pimaflex be effecting it?
