One way to know if your lizard is comfortable, is to observe how it responds to the temperature of the environment. When is cold, it flattens its body to receive the heat perpendicularly to its body.

If the temperature exceeds 43°C for too long, the lizard could even die.



Size: a 20 L tank is good to start for a baby lizard, and upgrade accordingly to its growth. A glass terrarium or tank of at least 40 gallons up to 75 in volume is good for an adult lizard to be happy in.

Habitat: Provide an environment similar to its natural one that satisfies the particular needs of the species. The "ground" of its tank should have deep or hidden "places" to satisfy the bearded dragon’s need for cover. It should also have branches and rocks either to hide in or for basking. This lizard is originally from a desert area, therefore humidity must be below 50%.

A reptile carpet or calcium sand is good for the "ground" of your lizard habitat.
