HELP! is this Crab dangerous

[rattslik]

I put this live rock in yesterday and today I wake up to see this Crab. He moved so fast that I couldn't get a good photo.

black claws or fuzzy = bad.

Agreed with black and fuzzy. Imo, only a few crabs are reef/fish safe. Crabs are opportunistic creatures with an appetite for any and everything. I’d set a bottle trap.

Forgot to add this information but my Blennie sits in the same cave as him but from a differnt while and its hasnt attacked him. Dont know if that would help

Judging by what I can make out, it’s shape appears to be that of one of the types that will go after your fish. Don’t be fooled by lack of aggression. Crabs will often take a few days surveying their new surroundings before making a move.

Those black tips are a dead giveaway, as soon as he's hungry and can grab your blenny etc, its gone. Get him out.

I'd make that crab into lunch for the blenny before the crab has a blenny for dinner.
