My new CBB

[The Shan Man]

Ok I know that some people might disagree with me putting a CBB in a reef tank but I have seen this done. I hand picked my fish from the LFS yesterday. He is a peaceful guy about medium to large size. I went over him with a fine tooth comb and he is healthy as can be. He even eat frozen food at the LFS... As soon as I put him in my 90 gallon with no other fish just corals he started hunting in all the rock looking for anything he could eat. He has not touched a coral and I have my figures crossed since I mainly have SPS. I tryed feeding him frozen brine shrimp today soaked in garlic but he did not touch it. Do you guys think since he was eating it at the LFS that he will eat again in time??? Is there anything I can do besides keep him full to make sure he will not touch any of my corals???
