Carolina Custom Cage 18D, African Zebrawood front panel Cage panels arrive ready to attach together with simple instructions. Habitats can be adapted for your specific reptile using the appropriate lighting, heating, backgrounds and other accessories. Many of our customers house their bearded dragons in our cages. The 18D model is equivalent to a 40 gallon breeder tank; regarded as the appropriate size for an adult bearded dragon. Those that start their baby dragon in a 20L tank should transition to an adult size habitat once the dragon reach 12 in length. Our 24D model cage is 33% deeper than our 18D model (front to back) and large enough to house two adult female bearded dragons. Males should always be housed individually after puberty. A lot of our customers simply prefer the larger 24D model because it allows them to outfit their dragons home with various items without it getting too cluttered. These cages may be used as habitats for a variety of reptiles; including bearded dragons, Rankin dragons, horned toad lizards, certain snakes, steppe runners, uromastyx, small turtles and tortoises.
