They livde to gether because the shell is a home for the hermit crab!
It depends who the Hermit Crab borrowed its shell from.
A shell provides protection and shelter for a hermit crab, which uses it as its home. The hermit crab carries the shell on its back and can move to a larger one as it grows. This symbiotic relationship benefits both the hermit crab and the shell.
When a hermit crab sheds you will see something come out of the shell and it looks like its dead it only sheds halfway and if you look inside the shell it will still be there.
Your hermit crab cam go fast depending on the whieght of the shell on the hermit crab. If the shell is light the speed of the crab will increase, if the shell is heavy on the crab the speed will decrease.

Seperate them.
The hermit crab probably got too big to live its old shell, which is why it moved.
When a hermit crab outgrows its shell, it will move into a larger shell.
a crab with a shell
A hermit crabs abdoman is long and soft. They insert it into the shell, and wrap it around the inside. They can change out of it any time they want.
Try to get another shell that you have that is simmilar to the original one. Then I would pit the hermit crab in a small tank with the new shell ans see that he gets into it.
