I have a hermit I got 2 weeks ago that left his shell that had a chip for this one. Is this too small? My older c hermit is in a similar one and can pull his whole body in.

It's snug, but I wouldn't worry. If he doesn't like the shell, he can always change. Just ensure he has a number of suitable shells to choose from and if he wants to switch, he will
