I curently have 3 herit crabs i had 5 but two of them dug themselves on a hole and i thought it was normal but boy was i wrong.I still don't know what happened but now i pick it up put it in their food dish then they should start moving if they don't pick it up and put them in their water dish/sponge and wait and see what happens in 24 hours.And you could also go to your local pet store (i went to petco) and ask them what else to do.
