White fuzzy hitchhiker crab

[taratronhex]

So I picked up some live rock the other day that was covered with Coraline algae, pretty much the only reason I got the rock! I put it in a temporary 10 gallon holding tank, mostly because when the pet shop employee got the rock, there was an emerald crab that he couldn't get loose and I didn't want to introduce that crab to my main tank. But it turns out there was more than that hitchhiker, I've ended up with two emerald crabs, three snails, and two kind of fuzzy white crabs that are much smaller than the emerald crabs and avoid them.

The emerald crabs are staying hidden in the rock, but I've seen both of the small white fuzzy looking crabs out on the open sand.

Is this in fact a gorilla crab?

Looks like a teddy bear crab perhaps. I think they are not reef-safe as they will eat fish and sps I believe,

thanks! yeah i got them in a 10 gallon tank for now, i plan to make it a mini brittle star and asterina tank, but they can keep the tank cycled for me until i can get the minis.
