How do I maintain the right nighttime temperature for my Blue-Tongue Skink?
Maintain a cool end of 75–80°F (24–27°C) for your Blue-Tongue Skink at night to ensure proper temperature regulation.
Target Temperature Range
The ideal nighttime temperature for a Blue-Tongue Skink is 75–80°F (24–27°C) on the cool side of the enclosure. This range is crucial for their health and well-being.
This gradient is essential because it allows the skink to self-regulate their body temperature. By having a warm side and a cool side, they can move between the two to maintain their preferred body temperature.
The cool end is particularly important at night when the skink is less active and relies on external heat sources to regulate their temperature.
- Basking/warm side: 95–100°F (35–38°C)
- Cool side: 75–80°F (24–27°C)
- Humidity: 40–60%
- Lighting: Use a low-wattage bulb for night-time lighting
Controlling Temperature
To maintain the cool end temperature, use a heat source like a heat mat or heat lamp on a thermostat. Set the thermostat to the desired temperature range.
Humidity can be controlled through the substrate and ventilation. Use a substrate like coconut fiber or orchid bark that retains moisture but doesn't become too damp.
Measure the temperature at the animal's level using a digital thermometer. Place it on the floor of the enclosure where the skink spends most of its time.
- Use a thermostat-controlled heat mat or heat lamp
- Substrate: coconut fiber or orchid bark
- Ventilation: at least one air exchange per hour
- Digital thermometer placement: at animal level
Observable Signs
If the temperature is too low, your skink may become lethargic, have a slower metabolism, or experience respiratory issues.
On the other hand, if the temperature is too high, the skink may become overly active, dehydrate, or develop heat stress.
Monitor your skink's behavior and appearance daily to ensure the temperature is within the optimal range.
- Lethargy at temperatures below 75°F (24°C)
- Overactivity and dehydration at temperatures above 80°F (27°C)
- Daily monitoring for signs of stress or illness
Additional Tips
Ensure the enclosure has a gradient of temperatures from warm to cool. This allows the skink to move to the cooler side if they become too warm.
Avoid direct sunlight on the enclosure, as it can cause rapid temperature fluctuations.
Regularly check the temperature and humidity levels, especially during the first few weeks after setting up the enclosure.
- Enclosure gradient: warm to cool
- Avoid direct sunlight
- Regular checks: temperature and humidity every day

Related questions
How often should I check the temperature at night?
Check the temperature at the animal's level at least twice a day, morning and night.
What if my skink is not using the cool side of the enclosure?
Ensure the cool side is at least 75°F (24°C) and provide a gradient of temperatures. If the skink still doesn't use it, consider adjusting the heat source or substrate.
How can I tell if the temperature is too low?
Signs of a too low temperature include lethargy, a slower metabolism, and potential respiratory issues. Monitor your skink's behavior and appearance daily.
