--...His set up looks like this, 12x12x30 it is tall not long. exo terra I got as a display model.

I just wanted to inform you about the problem I had with the exoterra cages and my BP. I had my guy in a Larger size, but still taller than it was long. He was fine for quite some time, and I managed to keep heat and humidity up just fine. However, a moth or two after I got him he started trying to reach the top, as snakes will. His nose just hit the screen, but he only had a little bit of his lower half supporting him, and fell over quite a bit. i went out and bought a new, lower tank immediately; he was falling over so hard he was literally hurting himself, and in that maybe twelve hour time span after he started doing it and before I got the new tank, he had bruised himself and cut open the top of his head. A little neosporin and a shed or two cleared it right up, and the bruise went down within a day or two. (His tank is in my room, where I've recently been spending a lot of time due to bad migraines, so it really wasn't any more than twelve hours, but he still bruised himself up pretty badly.)
So just be careful with those taller cages
