I have 2 questions about hermit crabs... 1. When they molt, how far down do they go? Do they go down a few inches, centimeters, or is it different every time? 2. Sometimes I see my bigger hermit crabs like Buster and Deadly tackling and sometimes it looks like they're punching with their big claw at each other. I usually move the one that looks like it's fighting and move it to a corner or something. Should I let the hermit crabs fight or move them?
