Crab ID please

[CrewCab]

I have recently noticed some new crabs that have came out of my TBS rock. They are small and pink in color and have two arms that they swing back and forth like they are trying to catch particals that float by. They never leave the rock and are quite comical to watch. I would love to know what kind these are. Sorry no pics.

Thanks

Porcelain crabs. Harmless and very cute. Related to hermit crabs. There should be a photo in the hitchhiker sticky.
