Even if I kept just one or two ball pythons, and not the 40+ that I currently have - I'll never - ever go back to tanks again. That's a personal decision for me. I hated the tank, the snakes hated the tank, and they eat much more reliably in the racks and tubs. If I want to look at my snakes, I take them out.
Every single one of my snakes is named and I consider them all pets first. If you asked me to choose one or two to get rid of, I couldn't. The ones that I produce to sell, I don't name.
It's been my experience that my snakes do much better in a tub environment than a tank. Most people who make the switch from tanks to tubs also report that their snakes do much better in that type of set-up.
I'm not saying that a tank can't be done properly, several people do - but ball pythons are really a poor choice to be a display snake.
