How do you tell if a hermit crab is too big for its shell?
If their big claw is down inside, the shell may be big enough or possibly a little too big depending on how deep the claw is in the opening. If the claw is too big to recede within the opening, your crab definitely needs a larger shell.
How do you know if your hermit crab is changing shells?
To check and see if your hermit crab needs a new shell, pick it up by the end of the shell and flip it over so that the opening of the shell faces up. If your crab is happy and comfortable in its little home, its body and all appendages will retreat inside the shell.
