Y'know, I've seen a few of these crabs amongst the acro branches that look similar in shape and looks. They've never left the acros though.

Yes...finally...confirmation.

I had one of these that came in with the live rock. It was small, and innocent enough, and to catich it in the 120-gallon reef with about 200-pounds of live rock wasn't something that I looked forward to. After about two years...and some significant growth...it began eating zoanthids. Also, mushrooms, but literally all of the zoanthids and it stripped them right down to the rock underneath them. I, by the time I first noticed that, tried to catch it but couldn't. Then, one morning I noticed that it had started to strip a blue torch. I was amazed and horrified at the same time. It eventually...and I mean just over a matter of days...stripped it down to the "bone." I never saw damage to an acro like that before or since. I finally caught it using a fish trap and a shrimp from the frozen food department of the grocery as bait, but that wasn't easy. It's down in my sump now. I believe this photo is clearly of the same kind of crab that you show in your photos. I believe it's a Xanthid Crab.
