listless scarlet hermit crabs

[IFoundNemo]

Yesterday I bought 2 scarlet red hermits for my nano. They looked healthy and spunky in the tank at the store. I brought them home and drip acclimated for almost an hour, and put them in. They maybe have moved and inch away from the spot I put them in the tank. Is there something wrong with them or are they just being lazy and will perk up later? I had one about a year ago that was very active. I don't really know much about hermits.:iamwithst
