Smaller animals, i.e. juveniles or hatchlings, should not be kept with adults, as they will be eaten. Overcrowding of an enclosure can cause fighting and stress. Because Bearded Dragons can move quite quickly, the enclosure should open from the top. They should be warm yet well ventilated. They require several inches of substrate such as large grained sand, gravel, outdoor carpeting, newsprint or towels.
Sand is recommended, as are branches to climb and bask on and caves or other hiding areas.
They are messy animals so the enclosure will need to be cleaned often. There should also be a basking area between 90 and 100 degrees Fahrenheit. The temperature should not fall below the mid 70s F at night. Bearded Dragons should be exposed to UVB light daily, by either direct sunlight or fluorescent lighting. Bearded Dragons should always be provided with fresh water and light misting occasionally.
