HCA: Hermit Crab Association

I need to add more sand in the crabitat because there is not enough sand for my crabs to properly molt. I just barely got them, but they are all starting to dig down. They can't cover themselves with the sand though because it is only half as deep as they are tall. I'm not sure if it is safe to move them yet is what I'm trying to say. Any suggestions? Also, for more detail so you can tell if they are molting or not, two of them are right next to each other and have not even tried to cover themselves while the third one is nowhere to be found....

If you can find all your crabs, you can simply dump in as much sand as you need.

If one really is buried, you’ll have to be more cautious. Add one inch of sand per day to avoid collapsing any tunnels.

Here is the caresheet for mixing and proper depth of substrate for the size crabs you have.

The general rule is 6" of substrate or 3 times more than your largest crab.

I would add more substrate ASAP since your crabs are trying to dig. If one sheds their exo on the surface there is a very good chance he will be eaten by your other other crabs.
