I used to believe that terrariums and the like were best for snakes, but I've since learned differently. I now house the majority of my snakes in tubs. They seem happier, if you can even guage a snake's happiness in terms we could understand. The snakes I house in tubs have silkier skin and just look better than the ones I keep in tanks. Those that are in tanks right now are only there because I don't have spare room in my rack at the moment.
