And that's where the problems will begin. You want something that is completely different from a Ball python's NEEDS. You have to realize that making sure this animal is safe, healthy and secure is much more important than having something pretty for your amusment.

BP's will live for 30+ years. Why not take the time now to make sure you start out right for her sake instead of doing what you want to appeal to you. BP's are not a great display snake anyways, a hiding BP is a healthy and happy BP.
If they are out during the day, its a sign of stress.

If you do want a nice enclosure, Starmom has already shown a very common cage that is MADE to meet the requirements for a BP, and will keep it very displayable for you. Tanks are just not the way to go in my opinion.

Less worrying about how pretty it is, and more worrying about making it correct for your BP.
