I think he'll like the crayfish. Their jaws are perfectly structured for crushing shells like that. What about eggs? Mystery snails would be a good addition, too. They breed easily, are cheap, and you can gut load them. If you can find them, lubber grasshoppers would be an excellent addition. They're flightless, massive grasshoppers from the South Dakota area. I have no clue how to breed the, but I bet they'd be a delicious snack for him.
Great idea exercising him with the ball. It looks like he enjoys it a lot, so whipping him into shape should be easy.
