I think it looks fine, I just wouldn't want the cleaning chore that goes with it
The accurite box should be on the cool end to read that temperature, the probe from the box should stretch over to the hot spot, to read that temperature.
I see nothing wrong with the set up, if the back and sides aren't covered, you might think about doing that, it makes the snake feel more comfortable in an all glass tank.
The snake is a bit difficult to see, dark pictures, and seems to be on the thin side, or is that just the photo, lol?
Even if he is thin, thin snakes can be fed up, just make his home comfortable for him and he will reward you with his eating prowess![]()
