IMO, NO
I have one in my reef tank that has been steadily consuming corals for months. He ate every bit of my Xenia and last night he polished off a nice leather frag that I paid 25 bucks for just last week. It wasn't until last night that I caught him in the act and made the connection to everything else that's been happening. I'm moving him into my FOWLR asap.
They are neat, beautiful creatures as long as you have plenty of coral to feed them.
