Ok so one if my crabs is the shy type who never really comes out of his shell much. He usually digs into the substrate and sand all the time and will sit there for a day or two, to the point I have to dig him up to introduce new food and water to him. (ivehad them both for about 5 months) well when I hold him it usually takes a little coaxin for him to come out. Well today he didn't come out he is lifeless and limp. And is sitting halfway out of his shell. I think he is molting! But I dug him up a couple of times thisweek... Couldi have hurt him?? now he is sitting on top of his sand half way out his shell!! I hope I didn't disturb his molt!! What can I do to help him out??
