i have had him in my 29 gallon community with clowns for about 6 months & he is doing excellent! I chose to do this not to play god, but so that i could have a unique fish that not every saltwater enthusist has & because it won't get much bigger then 2-3". He did however attack & eat me serpent star which made me very mad. He has not touched any of my mushrooms, so this is a start to seeing if he will be reef safe or not. Also, he learned quickly to avoid my anenome after some investigating.
