How often does a hermit crab change shells?

There’s no definitive answer for how often hermit crabs change shells. A lot has to do with personal preference, with some crabs changing their shells frequently and others less often. Your hermit crab’s species may also make a difference in how often they change their shell. While many hermit crabs change shells before or after a molt, when they shed the outer covering of their body, others do not. 

What shells are best for hermit crabs?

Hermit crabs can be quite picky when it comes to choosing a shell, so it’s always good to have a variety on hand and allow them to choose what they like best. Most hermit crabs prefer thick shells with a round opening, so it’s a good idea to always have a few of these styles available.
