How come my hermit crab won't change shells?

Question

I have three hermits. Two I have had for around a month, and one I have had for 3 days. The older ones a PP crabs and one has changed shells twice. The other ones haven't changed once, I know they change when they're ready and I provided around 7 shells for them but they don't change! I'm being paranoid but what do I do?

Also were is a place were I can buy shells CHEAP CHEAP CHEAP! I heard Hobby Lobby is good....

Answer 1

Well maybe the shells aren't big enough for them to move in or too big. Give them some time because maybe they like the shell there in.

Answer 2

Hermit crab mainly change shells when they are either too tight or don't feel secure in them. Your hemit crab's shell is probably perfect size for him/her, and feels comfortable. Just give it some time and it will probably change.

Answer 3

you shouldnt be so concerned ..when it gets too tight they will crawl out to a bigger shell unless you supplied too small of shells... if they are big enough dont worry... its instinct and there not that stupid
