Unidentified Crab

[mitch69]

I recently bought a needle coral from the LFS, and I have just noticed a small crab hiding in it. It is about 1cm across and has a whitish shell. Anybody any ideas what kind of crab it is? How big it will get? will it pose a threat to the rest of my livestock?

I will try and get a photo, if it ever ventures out of the coral.

check these out and let me know if any are close to the one you have, then I shall let you know if they pose a threat or not.

It doesn't really look like any of those, I suppose a bit like the Anemone Crab, if I had to chose.
