Crab ID

[Houndog]

Found this in a piece of live rock tonight, I have had the rock for many months and from several sources. In the top left hand corner of the first pic is the crab on a dime. I have put him in the QT tank for now...

Good/Bad?

Thanks for any help

Awesome pictures but it is going to be a bad guy.

I would say bad, any chance they get they will kill and eat whatever they can catch.

Looks like the body shape of a stone crab. Not reef safe. Pretty cool looking guy though!

Looks as if it is a male, and looks as if it might have some relation to the one I found today. Must be crab day.

Jim's right. It's another xanthid, maybe Liomera stimpsoni or something similar. But it's a female - the abdomenal flap is too wide to be a male. Probably bad.....

Most crabs are bad IMO(for reefs). After having hermits evict many of my snails I do not trust any of them. I just fed a hermit to my carpet today, it got mixed up with the snails I got today.
