Well so far, he hasn't touched NLS pellets, omega sea pellets, nori, spirulina or mysis. The timing of getting him was bad, as I noted ich in my tank and am now treating everyone, he is in with them as due to his size I didn't have a tank to put him in seperately. there has been no aggression between him and the other 2 tangs (mimic and yellow), they actually seem to like swimming together. I've given him lots of hiding spaces. He may have actually eaten while I'm not watching as he seems to hide as soon as he sees me.
