So your telling me it's more normal for a python to be able to see out of a glass tank, with people walking by and whatever else goes on in house, as opposed to a tub that's probably darker most of the time and it having newspaper and fogged plastic walls? I'm thinking the snake is more comfortable being in a tub setup. Also u don't need to use newspaper for substrate in tubs, it's just the most cheapest way to go and cleanup is simple and fast.
