Hitchhiking Crab

[richard t]

Purchased a piece of live rock today, and this evening have spotted a small crab. Body is about 10mm diameter, looks like a miniature eating crab. Very well camouflaged, very similar to rock it crawled out of. Have an inkling that its a small decorator crab - is that likely? And is it harmless?

Any chance of a pic?
