Crested geckos are popular pet reptiles, and it’s easy to see why! They have a sweet disposition, are pretty easy to care for, and have those adorable little eyelashes. But, like all reptiles, they need specific conditions to thrive, and one of the most important is temperature.
Crested geckos are ectothermic, also known as “cold-blooded.” They rely on external heat to regulate their body temperature. If their environment is too cold or too hot, it can lead to serious health problems.
This article will give you a complete guide to crested gecko temperature requirements and how to maintain the correct temperatures in their enclosure to keep your pet happy and healthy.
How temperature affects crested geckos
Crested geckos are ectothermic, which means they depend on outside sources to control their body temperature. This is different from endothermic animals (like humans), which produce their own body heat.
Reptiles like crested geckos thermoregulate, meaning they move between warm and cool spots to stay at the right temperature. If they get too hot or too cold, they can’t function properly.
If you keep a crested gecko as a pet, it’s really important to monitor its environment. Temperatures above 85°F (30°C) can cause major health problems and even death. Likewise, temperatures below 68°F can stress your gecko and make it sick.
Ideal temperature ranges for crested geckos
Crested geckos can’t regulate their own body temperature, so it’s up to you to keep their environment at the right temperature.
Daytime temperatures
During the day, you’ll want to keep your gecko’s enclosure between 72 and 78°F (22-25.5°C).
It’s important to create a thermal gradient within the enclosure, meaning one area should be warmer than the other. A basking spot of 80-82°F (26-28°C) is ideal, with the opposite side of the enclosure around 70°F (21°C).
Nighttime temperatures
At night, the temperature can drop a bit. The optimal nighttime temperature range is 69-74°F (20.5-23.5°C).
Some experts say the low 60s are fine at night. Reptile expert Philippe de Vosjoli has noted that low-60s are safe at night, and he would provide supplemental heat if the temperature dropped below 55°F.
Dangerous temperature extremes
The maximum safe temperature for a crested gecko is 85°F (29.5°C). Anything higher than that could be dangerous.
The minimum winter nighttime temperature is 65°F (18°C). While crested geckos can tolerate temperatures as low as 50°F (10°C) for short periods, it’s best to avoid prolonged exposure to such low temperatures.
Creating a Thermal Gradient: The Key to Crested Gecko Well-being
A thermal gradient is just a fancy term for a range of temperatures within your gecko’s enclosure. It’s super important because it allows your crested gecko to thermoregulate. Think of it like this: if they’re feeling a little chilly, they can move to a warmer spot. If they’re getting too hot, they can retreat to a cooler zone. Without this ability, they can get sick.
So, how do you make a thermal gradient?
- Put a low-wattage heat source on one side of the enclosure. You don’t want to heat the whole thing!
- On the opposite side, create cooler areas. You can do this with dense foliage, branches, and hides. The more hiding places, the better.
- Monitor the temperature. Use a thermometer to measure the temperature at the basking spot (the warmest area) and another to measure the temperature on the cool side. This will help you adjust your setup as needed.
By providing a proper thermal gradient, you’re giving your crested gecko the ability to control its own body temperature, which is essential for its health and happiness.
Heating Equipment Options: Pros, Cons, and Safety
There are a few ways to heat your crested gecko’s enclosure. Here’s a rundown of the most common options, along with the pros, cons, and safety considerations of each.
Heat Lamps
Heat lamps are a great way to create a basking spot for your gecko. They work by emitting infrared radiation, which heats the surfaces they shine on. For crested geckos, you’ll want to aim for a basking spot that’s around 80-82°F.
The downside of heat lamps is that they can be a fire hazard if not used properly. Always use a ceramic base for your heat lamp fixture, as plastic bases can melt or even catch fire. It’s also a good idea to use a timer to ensure the heat lamp turns off automatically after a certain amount of time. Start with a low-wattage bulb, like a 25-watt, and adjust as needed to achieve the desired temperature.
Ceramic Heat Emitters (CHEs)
Ceramic heat emitters (CHEs) are another option for heating your gecko’s enclosure. They work similarly to heat lamps, but they don’t emit any light. This can be beneficial because they provide a longer-lasting heat source without disrupting your gecko’s day/night cycle. However, the lack of light can also be a drawback, as it can make it difficult to observe your gecko’s behavior.
Heat Panels
Heat panels are flat, rectangular heating devices that can be mounted on the side or back of your gecko’s enclosure. They provide consistent temperatures and are generally considered safe for crested geckos. Heat panels are especially useful for maintaining ambient temperatures and are well-suited for crested gecko enclosures.
Heat Pads
Heat pads are placed underneath the enclosure and provide heat from below. While they can be effective at heating the enclosure, they also pose a significant risk of burns to your gecko, especially if they come into direct contact with the pad. For arboreal geckos like cresties, which spend most of their time climbing, heat pads are generally not recommended.
Heat Tape and Heat Cables
Heat tape and heat cables are flexible heating options that can be used to create a temperature gradient within the enclosure. However, they’re not as commonly used for crested geckos as other heating methods.
Heat Rocks
Heat rocks are artificial rocks that are heated internally. They’re often marketed as a convenient way to provide heat for reptiles, but they’re generally not recommended for crested geckos. Even with a thermostat, heat rocks can overheat and cause burns.
Keeping an eye on the temperature
You can’t just set up the enclosure and assume the temperature is right. You need to watch both the air temperature and the surface temperature of things inside the tank.
Digital thermometers are your best bet for accurate readings. You can get a digital thermometer gun to measure surface temps, and a digital probe thermometer to measure air temps.
Using a thermostat to control your heating equipment is essential. It’s the only way to reliably maintain a safe and stable environment.
Check the temperatures at least twice a day, once in the morning and once in the evening, to make sure everything is in the right range. Consistent monitoring is key to keeping your crested gecko healthy and happy.
Where should I put my crested gecko’s enclosure?
Where you put your gecko’s terrarium is almost as important as your heating equipment. You don’t want to put the enclosure in direct sunlight, as this can quickly overheat the tank. Also, think about the temperature variations in different parts of your home. For example, a room that gets drafty in the winter might not be the best place for your gecko.
You’ll also need to adjust the heating based on the season. If you’re using a heat source for the terrarium, you might need to adjust the room temperature to prevent overheating. Remember, these geckos need a temperature gradient to self-regulate.
Finally, keep in mind that humidity is also important for crested geckos. The temperature and humidity work together to create a comfortable environment for your pet.
Putting It All Together
Providing the correct temperature range is crucial for the health and well-being of your crested gecko. These reptiles thrive when they have access to a thermal gradient, allowing them to regulate their body temperature as needed.
To create this optimal environment, you’ll need to choose appropriate heating equipment, such as a low-wattage heat bulb or a ceramic heat emitter. Remember to position the heat source on one side of the enclosure to create a warm and cool zone. Using a reliable thermometer and hygrometer to monitor the temperature and humidity levels is essential. Safety is paramount, so always use a thermostat to prevent overheating and potential burns.
Consistent monitoring and adjustments are key to maintaining a healthy environment for your crested gecko. By implementing the advice provided in this article, you can prioritize your gecko’s well-being and ensure they live a long and happy life.
