Crabs have an exoskeleton which means their skeletons are on the outside of their bodies.
In order to grow larger, a crab must "molt" or shed its shell when the shell becomes too small to contain its body. The new crab shell is already surrounding the crab's body, but it is soft and needs time to harden into the protective covering we all recognize.

How do you get your pet hermit crab to switch shells?
First of all, you should make sure it actually needs to change shells because it has become too big for it. To make your hermit crab switch shells, place ONE crab in a small container that the cannot escape out of, put a shell in the container that you would like them to switch into. Turn off all the lights, and have a dark quiet room for them to switch in. Peek on your crab every hour. Well in the cage you should have more than three shells so whenever it grows it can just change when it wants to.The crab will change when it wants to, when it grows bigger it should change when it cant fit in that shell anymore. Make sure that the shells you put in the cage are bigger than its old one.

if they find another shell that they like better, they may just change right into it. I'm suggesting if you have a pet hermit crab to get around five shells for each crab try to pick around the size or maybe a little bigger for the shells. also i wouldn't buy painted shells they don't seem to like them very much. Hope that helps! :)
