Just to add on, the thermometer/hygrometer thing is at wal mart and its only 12 bucks. If you wanna stick with the tank then make sure you cover three of the sides. Depending on where you live, you might want to do some work on the top to keep humidity in. Once you figure out the humidity in your tank, do a search and you'll find some good articles for keeping humidity up in a tank. The foil treatment one by Argentra (sp?) is awesome and worked great on my set up.
