Setting Up the Environment

Temperature Regulation

Bearded dragons require a well-regulated environment with a temperature gradient in their enclosure. This allows them to thermoregulate their body temperature by moving between warmer and cooler areas. To achieve this, you’ll need to establish a basking spot and a cooler area.

  • Basking Spot: Create a basking spot where the temperature should be around 95-110°F (35-43°C). You can use a heat lamp, ceramic heat emitter, or under-tank heater to provide the required heat. Make sure to mount a thermometer near the basking area to measure and regulate the temperature accurately.
  • Cool Area: On the cooler side of the tank, the temperature should be between 75-85°F (24-29°C). This allows your bearded dragon to move to this side if they need to cool down, helping them maintain their ideal body temperature.

Humidity Control

Bearded dragons are native to arid grasslands and require a low-humidity environment. To maintain optimal humidity levels, follow these guidelines:

  • Use a hygrometer to measure the humidity in the tank. Aim for a range between 30-40% relative humidity.
  • Provide adequate ventilation to keep the air circulation smooth and prevent humidity buildup.
  • Avoid using a substrate that retains moisture. Instead, opt for a dry substrate, such as reptile carpet, newspaper, or non-adhesive shelf liner.

Providing Space for Activities

The size of your bearded dragon’s enclosure determines the space they have for activities and exploration. The minimum size tank for a single adult bearded dragon should be:

  • Length: 36-48 inches (90-120 cm)
  • Width: 18-24 inches (45-60 cm)
  • Height: 18-24 inches (45-60 cm)

Providing ample space allows your bearded dragon to exhibit their natural behaviors and promotes overall health and well-being. Additionally, ensure that there are some hiding spots and climbing opportunities, such as logs, branches, and hammocks, in the enclosure.

Remember, when setting up the environment for your bearded dragon, close attention must be paid to temperature regulation, humidity control, and providing enough space for various activities. By doing so, you will create an environment that keeps your bearded dragon healthy and comfortable.
