He's doing good...he was drinking this morning when I got up and before I left for work he was eating still naked and I know per text book that means he's sick but he's acting like a "normal" crab just no shell...
I may have missed this, but have you actually picked the crab up and manually reshelled it and ISO'd?
If a crab won't go into a shell after about 30 mins of being naked, we generally recommend reshelling it yourself then isolating in good conditions with high energy/nutritious food offerings like raw honey/all natural peanut butter/smashed egg, etc.
