Actually I think I've found something on line called a reptiflow 250 that might work, anyone know if its good / safe for controlling proper humidity?

As far as his behavior, I couldn't tie him down. Everything I've read says thats bp's are mostly nocturnal, yet he's running around his cage at all hours. I've never seen him curl into a ball either, except maybe when he's in one of his hides.

I'm assuming being a voracious eater and highly active is a good thing.
