Do pet hermit crabs change shells by themselves?

Yes, pet hermit crabs do change shells by themselves. In the wild, hermit crabs will search for and select new shells as they grow. They will also change shells if their current shell becomes damaged or uncomfortable. In captivity, pet hermit crabs should be provided with a variety of shells to choose from. The shells should be of different sizes and shapes, and they should be free of sharp edges or other hazards. Hermit crabs will typically change shells every few months, but some may change more frequently or less frequently.

Here are some tips for helping your pet hermit crab change shells:

* Provide your hermit crab with a variety of shells to choose from.

* Make sure the shells are the right size for your hermit crab. The shell should be large enough for the hermit crab to fit comfortably inside, but not so large that the hermit crab can't carry it.

* The shells should be free of sharp edges or other hazards.

* Place the shells in a shallow dish of water. This will help the hermit crab to soften its body and make it easier to change shells.

* Watch your hermit crab change shells. It's a fascinating process!
