Tank set-ups are not a lot of fun when it comes to humidity. It's why 90% of people start with tanks, and then discover the joy and ease of keeping their critters in tubs and never look back. I can't even imagine the fun of breaking down and cleaning/disinfecting a 55 gallon tank every month.

Honestly - if I want to see my snakes, I simply take them out of the tubs. If you're wanting a display snake, I'd recommend looking into other species of snakes. A ball python really is not a good choice for a display snake. They're really not out a lot, even at night. You'll have a pretty tank with pretty hides, and that's about all you're going to see, even at night. You may see him out for an hour or two, but that's about it.

Large lavish tanks are not for the animal's pleasure, they're always for the owner's pleasure. A ball python won't care either way.
