Hello to everyone, I have noticed hermit crab doesn't dig or bury itself in the sand or the FB. He or she just sits on the top. I've been watching it and it seems to be sitting there most of the time and than goes in it's shell "not all the way in" for awhile, like it's going to rest. The eyes seem to look normal and it's antennas seem to move around here and there. Is it molting? I also have coco huts, it will sometimes go in there but not to bury like the others.
