I have a 90 gallon reef aquarium that just finished cycling. Up until now both my ocellaris clownfish were thriving but recently one of them stopped eating and gasping very quickly. He seemed to have marine ich so i treated him in isolation with copper sulphate. He seemed okay after treatment so i put him back. He was okay for a few days then relapsed. I tried copper again but it did nothing. I tried a FW dip to relieve any parasites in the gills and to see if he had any worms. he looks fine other than the gasping but is now wasting away in my quarantine tank. I do know that the water in my quarantine tank is healthy. What could this gill damage be?
