i do not have one in my reef but, have seen them in a few reefs. They are "reef safe". But they will eat little shrimps, and possibly clams. They do how ever leave most corals alone. I personally wouldnt trust a fish with a jaw and snout like that in my reef. But thats just me and i have lots of fleshy corals and clams. I am sure that in a sps tank they would do just fine.
