They aren't coral or anemone eaters. I had one in my 150g with lots or different corals. He never touch anything, what he did do and the reason I found him a new home is that he would spit sand and cc all over my corals. Which my frogspawns, torch's and hammers werent really happy about. So I had to make the decision, him or corals? I really really liked that fish, but wanted to go a different direction when I went to the 210g. Great fish, good luck, but they do like to spit sand and cc all over.
