Temperature and heating, crested gecko care
Crested geckos thrive at room temperature. Ambient in the 72 to 78°F (22 to 25°C) range is ideal, with a slight nighttime drop to 65 to 72°F (18 to 22°C). Most homes never need supplemental heat; in fact, overheating is a far more common killer than cold.
Level: beginner. Part of: Housing.
- Above 82°F (28°C): acute stress. Appetite loss, lethargy, gaping. Sustained exposure is fatal.
- Below 65°F (18°C): slows digestion. Brief dips are fine and even healthy; sustained cold halts feeding.
- Use a low-wattage DHP (deep heat projector) on a thermostat if your home runs below 68°F. Never use an unregulated heat bulb or pad.
- Place a digital thermometer at the warmest and coolest points of the enclosure and verify with a temp gun weekly.
