I think it's really cool! If you can add more land area and keep the water filtered I'd go for it.... that said I don't have as much experience as these other guys Make sure the snake can dry off well when it needs to. Looks a lot like their natural habitat (minus some dirt). Is there any way you could add a shelf taking about half the tank with a lip so you could add some substrate. I'm thinking something that doesn't hold moisture like carefresh or maybe aspen?
