You might want to look into plastic tub housing. It is so much more stable for these snakes. A lot of folks don't like the look of it but there is one brand out there that for me anyways, has all the benefits of plastic with the clear view of glass. It's called Iris. It's not as easy to find as Sterlite or Rubbermaid but can usually be located at stores like Bed, Bath and Beyond, OfficeMax, Target, etc. You can often find a choice between a white lid or a clear one (I believe these are called their ClearView line). Just melt in some ventilation holes, put an under the tank heat source in place and you are good to go. With any tub you need to address the issue of the lid and any give it has that might allow your snake to escape. You can deal with that through the use of binder clips, C clamps, etc.

It might be well worth your time to use a tub for now and worry about fussing with that tank later on when your snake is bigger and already fully settled in.
