I've recently moved my crab Romulus into a 10gal, and he's seemed to love it- he's pretty active, has been visibly eating, climbs a lot, even dug a little hole for fun. But for the past few days, when he's not roaming around, he's sitting out in the open- except he's tilted on his back a little bit. It looks strange and it's kind of freaking me out, even though nothing APPEARS to be wrong with him. Do hermit crabs sometimes rest like that?
I also found him hanging upside down from the roof of his tank today, which was a first for me to witness. I was wondering why the plastic wrap kept ending up hanging down into the tank completely, and now I know why... he ripped it away to hang on the ceiling.

EDIT: Before he was kind of out of his shell, but now he's sleeping tilted back because he retracted all the way in.
