What is this?

Hey guys I'm new on this forum but not new to the hobby, I just set up a new reef tank and was looking in tank at night with flashlight, I ran across this guy, he was in one of my zoo colony's, he had a zooanthid stuck on one of his horns. Is this some kind of decorator crab, and is he reef safe? His claws are tiny, we was easy to catch so I put him back in.

IMO and IME no crabs are reef safe accept for the scarlet legged hermit. If you wish to keep that crab and have a sump, it belongs in the sump.

That's what I was kinda thinking. Thanks in the refugium he goes.

I would think it's one of the scariest zoas eating nudibranchs. Check out the link below, some of them look close to yours...

That crab gives me the creeps. Wow

Yeah, it gives me the creeps too. It makes my CBS and my SLF seem like lovely beauties compared to that creeper *knocks on wood*

I got him out of the tank and put him in my sump.
