He was very thirsty. When I put drops of water on the substrate he is on, he came over and sort of wrestled with the dropper. So I re-filled his tiny water bowl, and within an hour was hunching over it, and stayed there for about an hour. He is not digging caves anymore, not even using ones I make for him. He eats whatever I put in there, so I think I'll "power feed" him to see how many roaches he wants per week.
