OK please take everything I say here as objective as I'm not one of those guys who gives a nasty or sarcastic answers. That being said, I don't think a living vivarium will work with cornsnakes for a few reasons. 1. the humidity and cool temperatures you'll need to grow live moss will not be compatable with a cornsnakes heat requirements. 2. You'll also run the risk of scale rot and infection. 3. I like to avoid living terrariums with snakes as they can invite parasites that may be difficult to detect. both uinternal and external. I have about 8 living terrariums and none of them contain snakes. My advice to you would be try frogs or salamanders 1st or possibly geckos. These guys adapt better to the natural conditions and in some cases a living terrarium is essential. If you want more feedback I'll be happy to provide it. Living terrariums are great but again I wouldn't reccommed one for a cornsnake.
