They change shells because the hermit crabs will grow like us humans. Just imagine that if you were a human and had a shell, you would want to change right?? They like alot of differetnt colors and styles. They outgrow their own shells and need new ones once and awhile. :) I own three myself. I hop my info helped alittle :D If you need anything else write it on here:))
