I really want to replace the hand me down tank I was given, as it is kind of old and crappy. The problem is, I cannot find a replacement ANYWHERE. It is 36" long X 12" wide X 18 inches high. I would very much like this to be the last tank I buy for my guy, so I need something appropriate for a full grown adult. Any ideas on suitable alternatives to this size that will work for a full grown ball? (only 3+ feet now, but I know he's going to keep growing). I very much prefer a glass tank. That's what I have been using, I like to be able to view my snakes, and I have all the humidity and temps worked out for it.
