The first place I recommend any future, past, or present crab care taker go to. Amazing info and a wonderful staff!
The Hermit Crab Patch
A great site for info about crabs, the owner is such an awesome crabber! In the summer they sell crabs that are acclimated to living in captivity, and they'll ship them right to you. My crabs also love the shells we have purchased.

one word- crabulous! a must visit site for everyone crabby.
