I have a Sailfin tang that seams to be generally healthy but not completely. I have had it for a few months now. I did quarantine with copper for 30 days. Never showed any signs of any visible disease. I have had him in the display for about 30 days now and he eats Nori like crazy along with Rods food and LRS. He eats alot every day but his body seams to be thinning. other fish in the tank Tangs, clownfish seam to be fat. Is there some type of internal parasite like a tape worm in a mammal that could be causing this and if so what would the treatment be?
Thanks in advance
