Hermit Crabs Breeding?

[the_fish_man]

I have to hermit crabs in my saltwater tank and they never seperate like always next to eachother or on top of eachother. And If I pull them a part they go right back together so are they breeding?
I will post pics soon

no, they are gossiping about the snails.

As Doug said, it's likely that each one wants the other's shell.
