Great looking setup you have with lots of hiding spots for your new boy. I will mention you should get rid of the substrate to avoid any choking or impaction issues. He will at some point go to the bottom of his cage, whether that be to explore, hunt a bug, or whatever. There's a good chance he will shoot for a feeder and wind up with some of that substrate instead, which could be a bad situation. Just my two cents, and best of luck with your new little one.
