Crab

[BucNtears]

I was looking in the tank and saw a little claw pulling stuff of my liverock.The best look that I could get I can see some hair on the claws and ontop of the head.The crab itself as a blue/purple body.Not much to go on but can someone help.From what I've read not reef safe

I wouldn't trust any kind of crab in a reef tank. Unless they have a proven symbiotic relationship with a coral or are filter feeders they are not to be trusted IMO & IME.
