Return thank you for the information on prazipro. The damsel and clown fish were captive bred, maybe an inch maybe 1.5 inches. Did not see any skin sloughing, but did see stringy white poop from one of the clowns and I saw a new fluke on a clown 24 hours after all the fish were put together in the QT. Now one of the azure damsels has a small white patch on its side. Has had it 48 hours. In no apprent distress although now of the fish are actually eating. The butterflys white areas are all black colored, his mouth appears injured and he has popeye. I will be adding thise medications shortly. Again, THANK YOU SO MUCH GUYS!
