HI Could anyone give me some advise and insight on this fish. My LFS just got one in and he is a friend and said they dont get them in very often. Do they always eat corals and will they take flake foods ? I am going away for 3 weeks in the summer and dont want to risk if not 100% sure- LFS said he will feed mixture of frozen and flake and some pellets to see how it eats.Anyone here ever owned one ?
