I still think your not thinking about the BP's requirements. BP's live in burrows, tunnels, termite mounds. Underground 90% of the time. THEY require a tight space for their comfort. BP's like something touching them on all sides, this isn't a carpet python... Just because Germany says BP's require more room, doesn't mean it is beneficial or correct husbandry for the species.
I'm not bashing your dreams of a nice enclosure, you must understand the delicate mannerisms of BP's in particular. They are very easily stressed with large enclosures, if you meet their requirements of nice tight hides, thermoregulation, good ground cover for them to feel safe moving around, all the while providing perfect temps and humidity, then you very well could have a large nice natural enclosure.
My post was merely stating that we humans too often put our desires before the snakes NEEDS. Think about what any snake need first, and plan around that.![]()
