I was going to get one(or another type of small angel) but I have friends with then who have all lost corals(softies and LPS's) they dont mess with their hard corals but my buddy has had his shrooms and zoa's and alot of pieces of his leathers all but disappear in the tank. it was fine for like a year then one day, it bit a zoa, and that was that...and like ME said, we had to tear down his 150gal to get it...huge mess and he lost alot of stuff
