HCA: Hermit Crab Association

I just picked up 3 hermit crabs today. They came in a 40gallon tank. One crab is in a painted shell. I was told he wouldn’t come out it. I will be ordering new shells for them. How immediately do I need to get the new shells here?

Priority shipping usually works well (if it's a choice), and gets the stuff to you in about 1-3 days.
