Go, through the link I gave you in my first post. Its a really good tutorial on setting up a glass tank. If you cannot return the tank, consider providing as many "tight fitting" hides as you can. The tight fitting is a must for these animals and the large gapping wooden logs will not cut it in making them "feel" secure. The best I have found are the little "pot plates." Knock a hole out on the top or on the side and get rid of all the jagged edges. Provide many of these as you can.
