There are member's here that have some good write up on glass vivs, so I'll let them chime in. One last detail you might want to provide for them are your current hot/cool side temps and humidity.

My initial thought is that 30 gal tank is very large for such a small snake. These snakes like tight spaces and often times run into feeding issues when in a very large enclosure. Not that it can't be done but it takes a lot of extra effort from the keeper. Its also a pain to get the proper temps/ humidity stable in an enclosure that size.
