I just wanted to add:
I found having a glass tank to be a real pain. I live in Canada and my room temps go below 75 at night. Humidity was also a pain, even when I covered his screen with a wet cloth. That darn lamp killed the humidity hardcore.
I'm assuming that you want your snake as a "display" snake. I'd suggest looking into a PVC tank. I just got mine and am loving how easy it is to maintain temps/humidity compared to when I hAd my boy in an aquarium.
Of course, many people have had success with an aquarium set up. I just found it to be a real pain. I couldn't turn my fan on or have my window open without his ambient temps changing. Just something for you to ponder.
