There were supposed to be 3 sizes, one of them quite tall.
But as long as you get a good tub, you are good to go. Just make sure you fix the lid so the corners can't be pushed up. A determined snake can get out of a tub, even the ones with the snap on latches. The corners aren't real secure.
If you put a something around the tub, you can fix it to where they can't lift up the lid :)
