I think you have a very stressed BP, and I have a few theories of why your BP is stressed.

First, the enclosure looks too large for that small of a BP. Clutter it with decor plants or just crumble up newspaper. The water dish also looks too large and too high.

Second, the hides are much too large. Get/make two identical hides that are not too small, too high, or too large for the snake. You will need hides that tightly fit the snake, and so you know nothing really is too small for a BP. They like to crunch themselves into small areas, so get/make a hide with only one entrance that it touches the BP on all sides. Dog dishes or flower pots work wonderfully.

Third, what are your temperatures on both sides and your humidity level?
