I will try to take a half decent picture tomorrow, someone diagnosed it as possibly lymphocystis which seems possible but I'm still not 100%. I'll have to grab some prazi to keep on hand, it's one of the few that I don't have on hand. I've had a tough time recently with getting disease from all different suppliers, it just seems never-ending. I lost my very very beautiful massive mystery wrasse of two years due to flukes that I had only noticed a day before. Good thing I now have a coral quarantine tank, and two fish qt's. One for meds, one for seemingly healthy fish.
