That's for sale???
I think that all animals need stimulus. None of my snakes are kept in tubs except hatchlings and new snakes and even those have natural branches, moss for the arboreals, and something to hide in. Adults in tubs (usually arboreals) have substrate of moss, and natural branches as well as silk plants to provide areas to climb and hide. All the rest of my collection are in custom cages made from melamine and I'm slowly changing them all to natural earth cages. All the arboreals have live plants in their cages as well. This provides moisture and I feel cleaner air as well as something alive. I believe that all things need a connection to living energy. If I can provide it, I will. My snakes are out all the time, most will utilize their entire cage from top to bottom. Even the cornsnakes.
