Welcome to the site! :0) Just know the ball python should have at least 2 hides..one on the cool side and one on the warm side..he should also have some form of heat source (either light or heat mat) that will bring the warm side up to at least 85-90 (I think bp need 90 right?)..Also make sure he has a nice water bowl and good substrate..(Aspen, repti-bark, and sandi chips are all great choices)..Also make sure you have a thermometer with a probe and the probe secured on the warm spot so you can know how warm it is for him. And finally make sure his tank has a secure lid..after that your basiclly set to go with a nice enclosure..put in a few plants, maybe a climbing fixture for decor and your set :0)
