I had to get up for work at 3:30 and checked him out. He was active and on the ground next to the glass bowl of crickets. Heard a 'tink' and saw he had moved closer. I think he bonks his nose. So just to humor myself I dumped the crickets out and removed the bowl. Came back 5 minutes later and he was moved again eying up a cricket. I think the clear glass messes with him.

My ideas, either a safe paint to make the outside of the glass bowl visible, or tuck paper towel around it.

Thanks for any insight.
