Housing and Environment

The short version

• One adult needs at least 18×18×24 in (45×45×60 cm); 18×18×36 in (45×45×90 cm) or larger is better [7][15].
• Build in three levels: floor cover, mid-height branches and a few high perches [1][15].
• Give a warm spot of 82–85°F (28–29°C) in one top corner, and never let anything pass 85°F (29°C) [4][6][7].
• Mist in the evening (and lightly in the morning if your home is dry), then let the enclosure dry out between mistings [4][7][10].
• Low-output UVB is optional but recommended [7][9][10].

Enclosure size

• Adults: at least an 18×18×24 in (45×45×60 cm) front-opening glass terrarium. Sources differ on the ideal: one recommends 24×24×24 in (60×60×60 cm) [7], and another sets 18×18×36 in (45×45×90 cm) as the minimum for anything over 12 grams [15]. Bigger is better, and it leaves room for a real temperature gradient. Older care sheets allow a 20-gallon tank for an adult, but treat that as a bare minimum, not a goal [4].
• Hatchlings and small juveniles under about 12 grams do better in a smaller grow-out enclosure, at least 12×12×12 in (30×30×30 cm), such as a small front-opening terrarium or a large plastic tub, so they can find their food easily [4][7][15].
• Ventilation: a screen top lets in fresh air [4]. Many keepers cover part of the screen with glass or acrylic to hold humidity.
• One gecko per enclosure. See the Handling and behavior chapter for why this matters so much with gargoyles.

Layout

Gargoyles are mainly tree-dwelling, but they often rest low or on the ground by day, and they are less skilled climbers than crested geckos. That makes horizontal space and sturdy branches matter as much as height [1][5][15]. Build in three layers:

• Mid-height: thick branches and cork rounds.
• High: a few upper perches, plus a dense plant or hide near the top.
• Floor: an open area with leaf litter and a cork tube to hide in.

Provide at least two or three hides in total. Plenty of hides and decor help prevent floppy tail syndrome, because a gecko with good hiding spots is less likely to sleep hanging upside down [11].

Substrate

• Adults: a bioactive or naturalistic mix of topsoil (without perlite) and coco fiber with leaf litter holds humidity and supports live plants [4].
• Quarantine and hatchlings: paper towel is fine and makes it easy to check stool.
• Avoid loose, fine substrate such as sand. Gargoyles strike hard at food and can swallow substrate, so many keepers feed insects in a dish or with tongs rather than loose on the floor. See impaction in the Health chapter.

Temperature

• Heat one top corner only. Use a low-wattage halogen or incandescent bulb on a thermostat over one upper corner, so the lower half and the far side stay cool [4][6].
• Small tubs: a heat mat on one side of a small grow-out tub works, but always run it on a thermostat [4].
• Measure properly. Use a digital probe thermometer and an infrared temperature gun, not a stick-on dial.
• Keep a schedule. Run lights and heat 12 hours on and 12 hours off [7].

Humidity

Sources give slightly different targets: at least 50% and ideally around 70% [4], 50–70% [10], or an average of 60–80% [7]. A daily cycle works well:

• Evening: mist well, ideally after lights-out, so humidity rises high for the night [7].
• Next day: let it fall back toward 50–60% before the next misting. Exact spike-and-drop numbers are keeper practice, not proven.
• Why the cycle matters: keepers widely report that constantly wet air without a dry-down invites skin and breathing problems. Constantly dry air causes stuck shed, especially on the toes [10].
• Dry homes and winter: add a light morning misting, or run a cool-mist humidifier or fogger at night [4][7].
• Measure with a digital hygrometer placed at mid-height.

Lighting and UVB

• Day and night. Use a plain LED or 6500K daylight bulb on a 12-hour timer. It helps live plants and gives your gecko a clear day-night rhythm. Keep lights off at night; gargoyles see fine in the dark.
• UVB is optional but recommended. Gargoyles can do without UVB when their diet provides enough vitamin D3, which complete powdered diets do [4][10]. If you add it, use a low-output 2–5% linear bulb (the type made for shade-dwelling reptiles, such as a T5 ShadeDweller 2.4%) on the screen top for 12 hours a day, with the highest perch at least 6 in (15 cm) below the bulb [7][9][10].
• Replace UVB bulbs on schedule, about every 6 months [9]; one guide allows up to 12 months for a T5 tube [7]. UVB output drops long before the bulb stops glowing.
