I've known a few people who have attempted it, but I can't think of anyone who has continued with a naturalistic vivarium long term with any type of snake not just ball pythons. I love the looks of a natural looking vivarium with frogs or small lizards, but any kind of snake will tear the place up burrowing through the substrate, crushing plants under their weight or stinking it up with their copius amount of waste. I'm sure it HAS been done successfully, I'm also sure that it's probably a LOT of work which I don't think is the idea behind a bioreactive vivarium.
