Can anyone help me ID this crab and is it coral safe? I noticed my zoas have been looking poor and dissapearing and not sure if this guy is to blame. Video is attached along with some photos.

try these as I had the same problem and nice people posted these for me... I kept losing zoas, yellows first then once they were gone others started disappearing.. imo in the future my tank is a no crab zone.

crabs definitely can be questionable. I got lucky and got a nice emerald crab that only eats bubble algae but I know there are plenty of bad experiences.

Looks like a small gorilla crab before it gets bigger and hairier. Pulled a few of these from mine. Black tip pointy claws--not a good sign.

I had luck giving mine away to local reefers with a sump for castaways, so I didn't have to kill them--they came a long way on an airplane after all :)

That looks like a red eyed reef crab to me. I had one as a hitchhiker recently. Check if it has red eyes.

Thank you for this. I think it is a Xanthid species. Better that I get it out. On another hitchhiker note, I realized I got a mantis shrimp on my hands. Now thats going to be a project to extract out of the tank.
