Gargoyle Gecko Humidity & Temperature Requirements

Lighting

Although gargoyle geckos are nocturnal, they can benefit from some kind of light during the day. Aside from improving viewing, providing a source of daylight helps regulate their day/night cycle, and can improve activity, appetite, and overall health. For best results, lights should be on for 12 hours/day.

Gargoyle geckos benefit from a low-intensity basking spot, which is most easily created with an incandescent bulb (more on that in the Temperatures section ↓).

Don’t both with black/blue/red light bulb for night viewing or supplemental heat. Gargoyle geckos’ eyes function perfectly in the dark, and providing light at night can actually mess with their day/night rhythm. Also, nightly drops in temperature are actually healthier than providing heat at night. My opinion? Save yourself a few bucks and don’t bother.

What about UVB?

Many people will tell you that UVB is not necessary for gargoyle geckos in captivity—that they get all the vitamin D3 they need from high quality prepared diets. While it is true that not having access to UVB won’t necessarily kill a gargoyle gecko, there is a growing body of evidence that providing UVB substantially increases health and quality of life for reptiles previously thought not to “need” it.

For this reason, ReptiFiles recommends UVB lighting for all reptiles, including gargoyle geckos. Since gargs are crepuscular and typically hide behind leaves during the day, you don’t need anything particularly strong. We recommend the 12″ Zoo Med Reptisun T5 HO 5.0, 15w or Arcadia ShadeDweller kit for a gargoyle gecko kept in an 18″x18″x36″ enclosure. The fixture should be mounted over the mesh.

  • PRO TIP: If you use UVB, make sure that the fixture doesn’t have a piece of glass or plastic to “protect” the bulb. UVB rays are blocked by glass and plastic, rendering that bulb you just spent so much money on completely useless. Naked UVB bulbs are effective UVB bulbs!

Temperatures

Gargoyle geckos do best between 77-84°F, or 25-29°C. This happens to be right around room temperature in most homes, so it’s easy to keep your gecko comfortable.

Incorporating a temperature gradient (zones of cool, medium, and warm temps) is ideal. You can expect cooler temps to settle in the lower levels of the terrarium and warmer temps closer to the basking bulb.

  • Basking surface: 84°F (29°C)
  • Air temperature: 77-84°F (25-29°C)
  • Cool zone: 72-74°F (22-23°C)
  • Night air temperature: 68-77°F (20-25°C)

(Numbers from Frances Baines’ UV Tool)

The air temperature should never get higher than 86°F (30°C) or lower than than 65°F (18°C)! To make sure you don’t accidentally cook (or freeze) your gecko, experiment with terrarium temps before bringing it home.

Many people claim that it’s perfectly fine to keep a crested gecko at room temperature without a heat source, but it’s important to remember that crested geckos are ectotherms, which means that they can’t produce their own body heat and rely on natural heat sources (ie: sunlight) in their environment to help them regulate their metabolism and digest food. In my experience, the most common cause of lethargy, poor appetite, and illness in crested geckos is lack of access to a heat source.

How to Heat Your Gargoyle Gecko’s Enclosure

The best heat source for a gargoyle gecko is a heat lamp. White or clear low-wattage incandescent/halogen bulbs work very nicely.

If you are using a small terrarium hood like the Zoo Med Naturalistic Terrarium Hood to house your lights, I recommend the Exo Terra Daytime Heat Lamp. The exact wattage you need will depend on enclosure size, design, room temperature, and other factors, but start with the 25w and go up or down from there depending on your needs.

If you are using a small 5.5″ dome lamp like Zoo Med’s for your heat bulb, then I recommend starting with the 25w Zoo Med Repti Basking Spot Lamp. Dome lamps are also compatible with dimmers, which can be a very handy feature for controlling the basking temperature in your gecko’s enclosure.

Measuring Temperature

Keep tabs on your surface temperature gradient with a quality digital temp gun like the Etekcity Lasergrip 774. Just point the laser where you want it, and boom, instant temperature readings. Avoid ribbon/stick thermometers or gauge-type thermometers — they’re cheap, but they also don’t work. At all.

You can check air temperatures with a quality digital probe thermometer, like the Zoo Med Digital Thermometer and Hydrometer, with the temperature probe placed in the basking area.

Lighting & Heating for Hatchling Gargoyle Geckos

Hatchling gargoyle geckos (under 13g) are often housed in small “grow-out” enclosures to keep track of their health during this vulnerable phase of life. If you have or are planning to get a hatchling gargoyle gecko, there are some special accommodations you will need to make in terms of UVB lighting and heating.

Lighting

If you put a UVB lamp on top of a hatchling’s tiny grow-out cage, you will likely expose it to dangerously high levels of UV. To keep your hatchling safe while still providing the benefits of UVB light, use a forest-strength compact coil bulb in a 5.5″ dome fixture hung from a reptile lamp stand. Turn off the light at night.

Specific products we recommend for hatchling lighting:

Heating

There is not enough room on top of a hatchling terrarium to accommodate a heat bulb. To make sure that your gecko still gets a supplementary heat source, stick a small heat pad to one side of the enclosure, and connect that heat pad to a proportional thermostat. Place the thermostat probe between the heat pad and the glass/plastic of the enclosure to make sure that the temperatures your gecko is exposed to don’t go higher than 85°F/29°C. Turn off the heat pad at night.

Specific products we recommend for hatchling heating:

Humidity

Gargoyle geckos prefer slightly lower humidity levels than crested geckos — roughly 50-70% on average. This can be well maintained with daily misting and a moisture-retentive substrate. Make sure to let it dry to 50% before misting again, as constant moisture encourages mold and mildew growth, subsequently making your gecko sick.

Misting is also a reliable method of making sure your garg stays hydrated, as they rarely drink out of water dishes. (You should still provide a shallow gecko cup of fresh water anyway.) Depending on how well your terrarium holds humidity, I recommend misting heavily (up to 80-100%) in the evening and then again (lightly) in the morning. Your gecko will then drink the droplets off the terrarium walls and accessories.

Do not use distilled, softened, or even filtered water for misting! Tap water (assuming that it’s safe for humans to drink) contains minerals vital to your gecko’s health. Yes, this means you’ll have to clean up water spots, but it’s worth it. Here’s why.

  • PRO TIP: Already have hard water deposits? No problem! They come off easily when you scrub with a lemon juice-soaked cotton ball.

Keep track of the humidity levels with a quality hygrometer. Again, I recommend the Zoo Med Combometer mentioned above, since it’s a 2-in-1 package with reliable readings.
