Recently purchased a yellow eyed Kole Tang and have had it for about two weeks. I cant get this sucker to eat anything. He has cleaned all the algae from my tank, but anything I put in the tank, he wont eat. I have put in nori, romaine, frozen mysis, pellet. Its a 55gal, with 1 clown, and two damsels, the tang was the last addition, but he is medium sized. Is there anything I can do to make this guy eat?
