Yellow tip hermits problem

[Tcox]

Hi crew.
I got about five new yellow tip hermit crabs from my lfs about two weeks ago. After acclimation, these guys have just been hanging out for over two weeks, not moving. They will dig through the substrate and dance their antenna's but have not moved from their spot of introduction. Any ideas on why they've elected to stay still for this long?

Scarlet Hermits are like this too. As long as their antenna moving they are fine. Now you are going to have me Googling Yellow Tip Hermit Crabs since I've never seen one :hammer:
