I have had one snake die in a tub and she was over 20 years old. My cousin purchased her as a baby import from a pet store and kep her for 19 years then gave her to me because I was just getting into snakes. I had her for 6 years and she died. Her entire life was spent in a tub... Now as for other snakes that have died that would be 12 others and they were in tanks and died due to poor husbandry because no matter what I did I coujld not keep the correct conditions.
