Thanks for the speedy reply.

Given that it's Xmas time, I'm kind of short on money for a new enclosure. Would partitioning this one off work in the meantime? I was thinking about cutting a piece of plywood to make a new "end" for the tank. Seems like that *should* effectively reduce the area I'm trying to heat. When I first got it from him, the thermometer in the tank read 70 degrees. He said it was always around that, so I put aluminum foil on the outside corner where the snake's rock is, and it's got that corner around 80.

Also, he's got a vine and climbing stick in the tank.... do BPs really make use of those?
