Today I discovered that my Red Sea Convict Tang has some kind of extension (worm like) grow out from his belly. I cannot put medication in to the tank because it is a mix fish and reef tank. Copper will kill everything else beside the fish. Should I try to catch the fish and give it a fresh water bath? will this kill the parasite? I am not sure what to do, please advise. :help:
