Hairy Crab ID Please

[rroselavy]

Hey all-

I bought a Stylophora pistillata Coral today, and I found a tiny (1/4") brownish-pink hairy crab in the branches picking at either the polyps or slime (cannot tell). I was able to separate him and too a few photos. Sorry for the lack of DOF. His eyes are green, and his claws are white and orange.

I did a few searches so far with no positive ID. Can anyone tell me what he is, and whether he is good/bad?

Thanks!

all of that hair leads me to think that he is one of the bad ones, but it is kind of hard to tell.

Thanks all. It may be a juvenile Pilumnus sayi crab. Here is a google image link to a thumbnail of one. You can pull up a larger image on the same page.

I do not think the one I have has as much hair (spikes?) on the claws and mine is a bit more red-brown than the picture, particularly the body.
