Help me ID my hitch hiker crabs..

I found 2 of these crabs on my Acropora and one on a monti I bought today. I think the smaller smooth one is an acro crab. The big hairy one I would guess is bad news. The other one.. I'm not sure.. Should I let the big hairy one live in the sump or flush him? I only have snails in the sump.

the smooth on is an acro crab which is great, the one with the black claws = bad. the other looks like a gorilla crab also, but can be a emerald crab.

Acro Crab = Good, put him back on the acro he came off of, you'll be glad you did.

The big one with black claws is a teddy bear crab I think. Black claws = predator. Put it and the other one in the sump. You can toss in a piece of shrimp in the sump once a week if you want to.
