I used 100 to 110F basking for these fellas. I also provided deep substrate right under the basking lite. They often laid upside down IN THE SUBSTRATE.

Now heres something funny, I had many many BHPs and they were not fond of snakes, hahahahahahahahahaha got me. At first I attempted to get hatchlings to eat gophersnakes(use to be lots and lots here)(drought changed that) Ratsnakes, yes we have them, and no, they aren't going to be fed to BHPs hahahahahahahahaha

The dang things just ate rats, good thing too.

Would love to see pics of yours upside down, miss that. Best wishes
