I don't own any, but the zoo I volunteer at does. They're really easy going snakes, the ones there love eating a lot. They're nervous to handle though. Bit all over the place, but I've never heard them bite any of the keepers, and a calmer larger female is used in the educational "show" for visitors without issue. That's about all the experience I have with them, not my thing but still pretty cool looking snakes.

Oh and they seem to really use any space available, horizontally and vertically
