What kind of crab is this (Picture)

[cam78]

I was breaking up a zoo rock and this popped out after I gave the rock a wack! Is it reef safe, should I put it back in the tank. What a hitchhiker!

Yikes! Look at the hitchhiker thread in the archive--might be a gorilla crab?

Someone with more knowledge will be along shortly, I'm sure, but look at that hitchhiker thread. It's the first place I go to for weird stuff from LR.
Others have posted that pointy clawed crabs are usually more predatory.

See if this is like it.

Gorilla crab. A predatory crab and they will eat fish when hungry and given the chance. Get rid of him or place him in your sump.

Sold, gave him to LFS, they were very interested in him.

Looks like it could also be a red mixtrax crab. I'd still put it in the fuge/sump if you can.
