Anyone recognize this hitchhiking crab?

This little guy appeared a couple weeks ago... So far he hasn't harmed anything and i've witnessed him eating algae, so i'm hoping he won't end up eating any corals.. He's about 1/2" wide at this point, very furry, and has purple/blue claws and hints along his body.

Not sure of the species, but since it's all fuzzy it might be teddy bear crab. Usually not a good thing. Keep an eye on him..

With hitchiker crabs, it is often next to impossible to make a positive ID, even for a professional, because so many species are nearly identical. Better remove him to the fuge (or the toilet:badgrin just to be safe, as most crabs are omnivores.

Yeah, if you have a sump or a refuge, try to get him in there.

i wouldnt put a predator like him in a refugium..."a place of refuge for copapods, amphipods and other microfauna away from predatory fish and invertebrates"
