I just got a Kole tang on Monday. I did not QT him as it is my first fish in the tank so there is no competition for food. (I know probably should still) He ate well at the LFS but now that I got him home he won't eat. He is grazing on the rocks and substrate, so from what I gather that means he is eating something. I have soaked Nori in Garlic with no luck. I understand that they don't always eat right away, but when is too long? Any other tricks or advice is appreciated.
