Strange Crab

[d_dog17]

Hey guys,
I added some new live rock a few days ago, after quarintine/cure for 3 weeks. I thought I got most of the bigger crabs off of it, but tonight I noticed a very strange crab. It is a reddish color, slightly fuzzy, about half an inch. It has what appears to be a flat, white, random shaped rock on its back. It carries it around like a hermit does, but it is pretty flat. It does not live inside the rock, just carries it around like a shield. Any ideas? Thanks- Dave

Might be a decorator crab, but without a picture.....it will be really hard to ID. Most of the crabs around here are xanthid crabs.....except of course for the hermits.
