2 of ours are in tanks, one is in a tub. The tub is so much easier to maintain for the snake's needs.

You may not agree with tubs, and we didn't either until we got our pastel. We aren't going to switch our other 2 over to tubs, but the snakes we get in the future will be in tubs.

I understand that you don't agree with tubs, but like others have said, your not going to get much of a good response for your opinions about it, especially from people who feel tanks are wrong. People are very sensitive about their animals and can get extremely defensive if they feel they're being criticized for how they keep their pets.
