I have or had this hermit crab and he buried himself for about 3 weeks and but I had to deep clean the tank because it had mold in it so I dug him up while cleaning and he was fine but and it didnt look as if he was molting so he walked around a bit and finally I buried him/her. A week later I dug him/her back up and the shell was there but no crab and all the other shells were empty as well so I dug around in the coconut fiber and no crab, in the tank i use half coconut fiber and sand made by zoomed anyway still no crab? Its as if he disapered, by the way no limbs or parts of a crab either!
