Is this a bad crab?

[Rich_Lucas]

I found this in some live rock I purchased. I've gotten him isolated now, but can someone tell me if he's bad news?

I donââ"šÂ¬Ã¢"žÂ¢t trust him, he looks guilty or something.

He was just mad that I ran him out of the piece of rock he was in. =)

Most here will tell you that any crab is unsafe. This one looks like one that I was told to get rid of, not the same color, but the same body shape and configuration. About the size of a thumbnail or a little smaller? If I'd had a sump, he'd have gone in; as it was, he is just gone....

xanthid? zanthid? I can't remember. Post the picture in the invertebrate forum, and you'll get the right answer.

Big fat claws = bad crab.

looks kinda like a teddy bear crab to me. I'd drop him in the sump if you've got one
