Enclosure
As is the case for most reptiles the bigger the vivarium the better. You also must remember that Bearded Dragons
grow up fast, so they will soon outgrow a vivarium that was suitable for them when they were younger.
An ideal vivarium for an adult or a pair is 48x24x24 inches (120x60x60 cm). You should ensure that this is purpose built with adequate
ventilation.
Substrate
Sand is most often used for adult bearded dragons but there is
much debate about the best substrate for them. It is though that sand can cause impaction. Impaction is caused when reptiles accidentally
ingest foreign bodies with their food that they are then unable to digest. It is generally recommended to keep juvenile bearded dragons
on kitchen towel.
Humidity
Bearded dragons require a dry atmosphere with humidity between 24-40 percent.
Temperature
The daytime temperatures at the hot end of the vivarium range between 35-43C (95-110F)
and the cool end of the vivarium should be between 26-30C (80-85F). Temperatures at night should be no lower than 16C (60F).
Lighting
Apart from the light in the basking area Bearded Dragons require an Ultraviolet light source.
This is very important otherwise they will not be able to manufacture vitamin D-3, which will eventually lead to their death.
