I love her.
If you're just going to have one, get a tank and make it look pretty. Like a show-case. Something spectacular to look at that the snake will feel at home in. It's true tubs hold humidity better, but tanks are prettier and besides, you can always just get a water bottle to spray them with a couple times a week. XD I wish I could have them all in show-case style tanks, but I'd have no place to sleep. LOL.
