ID Crab please :)

[newbienz]

Found two of these crabs hitch hiking in my blue sponge. Can any one ID these? Are they good or bad? Reef Safe?
They are about 1/2" from leg to leg. The red thing next to it is red macro algae.
Thanks in advance.

looks like they might be a decorator crab or a teddy bear crab

i agree....those pinchers are not round at all.

I would keep him in a refugium if you have one, I love oddball critters like that. Prolly is not good. On the same note though pointy claws does not mean bad. Porceline crabs have very sharp claws and they are perfectly fine. I think they are the exception though.

Thanks for the replies. I tried looking up teddy bear crab and decorative crab, but couldn't find any that looked similar. They also did not have the antennae that the crabs I found have. Any other suggestions?

They were hitch hikers on a piece of coral I purchased
