I am new to BPs and have never owned a reptile, but have kept numerous freshwater fish and amphibians and as a result have a plethora of empty aquariums. Originally, I was planning on keeping a potential BP in an old aquarium, but after doing research have come across several sources that say glass tanks are unsuitable due to humidity issues and the lack of security. What type of setup do most people on here keep their BPs in? If there are significant benefits to using a vision-type cage I will absolutely do so.

What is the general rhetoric here regarding bioactive setups? I have a vivarium for my poison dart frogs that works seamlessly but I feel as if something as large as a ball python can't really work in a true vivarium.

Lastly, is there a guideline or calculator for enclosure size? I've heard from several places that a 40B is is standard but I prefer using measurements rather than specific cages.
