I've had my BP for about 5 weeks now, and for the first few days he went mental in his aquarium regardless of the wall coverings (fake plants) and hides. Husbandry was within standards (a pain in the ass mind you), but until I lined the back/sides with cardboard (now 1/2" building sheathing R2.5).

Once he is up to size this summer I'll probably opt for an Animal Plastics T8 with a divider (excuse to get another snake, maybe a mojave female for long term?)

Also one thing I have noticed with most is that the second you put a ball python down, they move towards somewhere they can hide. That does not necessarily mean that they are constantly trying to get away while being held, but they seek privacy over exposure instinctively. That being said, if they like to hide, it is unlikely they will enjoy being exposed at all times. I sure wouldn't like my house to have clear walls.
