There's a book out there called "The Art of Keeping Snakes" which takes a different approach to viv design for snakes. The setup that this book advocates is really for advanced hobbyists looking to keep a snake in a naturalistic glass viv. This setup is totally impractical for a keeper with even a small colony of animals, the maintenance alone would be a full time job. I'm talking about live substrate, real plants, and all that. However, the average glass tank snake keeper falls far short of this in their so called "natural" setups with shredded wood chips for bedding and a few plastic plants.
