So I've had a Kole tang for about 2 weeks. The first day he was in the tank he was calm, pecking at rocks swimming slow, enjoying life... Late that night I'm guessing he saw his reflection and has just been darting around the tank from corner to corner looking at the glass going nuts and darting back, then hiding in the rocks. He didn't eat for about a week, so I bought every herbaviore food my LFS had and finally found out he loves red algae with garlic.... So long story, but he's lost about all his color I assume from poor eating and stress, I don't think he's sick, but does this picture look as bad to others who have had tangs as it does to me? The first pic is 2 weeks ago when I brought him home, the 2nd is tonight.
