Crested gecko stress signs can be the result of incorrect humidity and temperature levels.

Temperature Levels

The Crested gecko natural habitat in New Caledonia is tropical and humid with temperatures ranging between 72°F to 86°F, depending on the season.

When kept as pets, you need to ensure that your Crested gecko’s enclosure is kept at temperatures of 72°F to 75°F and no more.

If your Crested gecko is kept at temperatures higher than 80°F for long periods of time, it can result in heat stress and be fatal.

As Crested geckos are very sensitive to heat, it only takes a few hours of being exposed to very high temperatures to result in heat stress.

To avoid this condition, you must ensure that your Crested gecko has:

  • A cool spot. You need to ensure your gecko has a cool spot with a temperature of 68°F to 70°F. And at night, the temperatures must drop to 65°F to 69°F
  • Thermostat. To achieve the ideal temperature for your Crested gecko’s enclosure, you will need a thermostat to track it

  • Constant laying or hiding

Humidity should be 60% during the day and at 80% during the night.

To ensure your Crested gecko’s enclosure maintains the correct humidity levels, follow this advice:

  • Use a spray bottle with purified water (never use tap water) to mist the tank
  • Mist twice per day – light mist in the morning and a stronger one at night
