Size is an extremely important factor for any bearded dragon cage. Never put your adult dragon in a tank that is smaller than a 40 gallon breeder. If you cannot get your hands on a breeder tank, settle for no less than 75 gallons. Ground area is more important than height, but make sure that your beardie still has plenty of room overhead. You will later be installing some rather cumbersome objects, so make sure to keep all installed objects into consideration. I've found a free bearded dragon book. It's great, you can download it from here: Best Bearded Dragon BOOK is FREE. Download Bearded Dragon Quick Start
It's free with over 100 pages, and lots of info about how to care and raise bearded dragons.
