Rack vs Glass Tank/Aquarium or else?

[Pythonfriend]

I think racks are better for the snake as they hold heat and humidity better. Also balls like to be hid away in smallish areas, so racks are better at offering that. If they are given to much space or don't feel secure they don't do as well.

not true, in the wild, or in a semi-domesticated state, they may crawl a mile in one night. they like to hide during the day, but when its dark they like to move. its obvious that if you provide them with more, they will like it. they are quite good at climbing, and they are excellent swimmers.
