Gargoyle Gecko

📌 Description

The gargoyle gecko (Rhacodactylus auriculatus) is a nocturnal, semi-arboreal gecko from New Caledonia. It is named for the bony-looking bumps on the head, which give many animals a horned or gargoyle-like profile.

Adults usually reach 18-25 cm and are stockier than crested geckos. They have strong jaws, a prehensile tail, and good climbing ability, but they do not climb glass as effortlessly as day geckos. Unlike crested geckos, gargoyle geckos can regenerate the tail, although the regrown tail often looks different.

With good care, gargoyle geckos commonly live 15-20 years or more. They can become calm, but many are more assertive than crested geckos and may bite if restrained.

🌍 Distribution

Rhacodactylus auriculatus is endemic to New Caledonia, mainly in the southern part of Grande Terre. It lives in humid forest, shrubland, maquis vegetation, and rocky or densely vegetated areas.

Important habitat features include:

• Vertical and diagonal branches
• Dense foliage and bark retreats
• Moderate temperatures
• Humid nights with drier daytime periods
• Fruit, nectar, and insects

In captivity, the enclosure should be tall, cluttered, humid but ventilated, and full of branches, cork, and foliage.

⚖️ Legal status

As checked in April 2026, Rhacodactylus auriculatus was not found in the CITES Appendices or in the local EU Wildlife Trade Annex text check used for this project. The species is assessed as Least Concern by IUCN, but it is endemic to New Caledonia and local export of native wildlife is restricted.

National and local rules may still apply to keeping, sale, transport, breeding, and proof of origin. Keep invoices and breeder records.

Buy captive-bred animals only. Captive lines are well established, so wild-caught or unclear-origin animals are unnecessary and should be avoided.

The Bern Convention is not usually relevant unless a species is native to Europe or covered by local conservation rules; check current national guidance for the country where the animal is kept.

🤌 Husbandry

An adult gargoyle gecko needs a vertical enclosure. A practical minimum is 45 × 45 × 60 cm, while 45 × 45 × 90 cm or larger is better for active adults.

The enclosure should have:

• Branches, cork tubes, vines, and textured climbing surfaces
• Dense foliage at several heights
• Several secure daytime retreats
• A feeding ledge or stable bowl holder
• A shallow water dish
• Good ventilation with humidity retention

Solitary housing is the safest default. Males fight, females may compete, and mixed pairs can lead to stress and repeated breeding. Keepers should not house them together long term unless they are deliberately breeding and can separate animals quickly.

💡 Lighting

Gargoyle geckos are nocturnal and crepuscular, but they benefit from a clear day-night cycle. Provide 10-14 hours of light depending on season, or a simple 12-hour cycle.

Low-output UVB can be beneficial when installed over part of the enclosure. The gecko must have shaded retreats and the ability to avoid direct UVB completely.

If UVB is not used, use a complete gecko diet and supplements that provide vitamin D3 safely. If UVB is used, avoid excessive extra D3.

For UV planning, treat this species as Ferguson Zone 1. Aim for about UVI 0.5-1.0 in the upper exposed area, while leaving retreats and a gradient down to shaded areas near zero UVI. This usually points to a low-output UVB tube such as a ShadeDweller-style or 2-7% T5, chosen for the enclosure height; measure with a Solarmeter 6.5 when possible, because reflector, mesh, distance, and lamp age change the real exposure.

🌡 Heating and temperature

Gargoyle geckos need moderate temperatures and are vulnerable to overheating. They may tolerate normal room temperatures if the room is stable, but a gentle gradient is still ideal.

Useful ranges:

• Gentle basking area: 27-29°C
• General daytime range: 22-26°C
• Night: 18-22°C
• Avoid sustained temperatures above 29°C

Use a thermostat for any heat source. A low-wattage overhead lamp, deep heat projector, or ceramic heat emitter can work if it does not overheat the enclosure. Do not use heat rocks.

Measure temperatures at the top, middle, and lower enclosure. In summer, cooling and ventilation may matter more than heating.

💧 Humidity and water

Gargoyle geckos need a humidity cycle. A practical target is around 50-60% during the drier part of the day, rising to 70-90% after misting.

Mist in the evening and lightly in the morning if needed. The enclosure should dry partially between mistings so it does not become stale, moldy, or constantly wet.

Most gargoyle geckos drink droplets from leaves, glass, cork, and branches, but a clean water dish should still be available. Dehydration can cause poor shedding, sunken eyes, lethargy, and reduced appetite.

🌿 Enclosure and decoration

The enclosure should be dense and three-dimensional. Gargoyle geckos use branches, cork tubes, ledges, bark backgrounds, and foliage for movement and security.

Suitable substrate options include:

• Coconut fiber mixed with organic topsoil
• Tropical forest reptile substrate
• Sphagnum moss in selected humid areas
• Leaf litter for cover
• Paper towel for quarantine or medical monitoring

Bioactive setups can work well if drainage, plants, clean-up organisms, and airflow are established. Use sturdy plants, because gargoyle geckos are heavier than crested geckos and can damage delicate growth.

Secure all heavy decor. These geckos jump and climb with force, and unstable branches or cork can cause injuries.

🪳 Feeding

Gargoyle geckos are omnivorous. In captivity, the staple diet should be a high-quality complete gecko diet formulated for New Caledonian species, mixed with water according to the instructions.

Offer fresh prepared diet two or three times per week for adults, and more often for juveniles. Remove old food before it spoils.

Live insects add enrichment and protein:

• Crickets
• Dubia or discoid roach nymphs
• Black soldier fly larvae
• Silkworms
• Small locusts where legal

Insects should be gut-loaded and dusted with calcium and vitamins as needed. Do not rely on fruit puree, baby food, honey, or insects alone.

🥚 Breeding

Breeding should be planned carefully. Gargoyle geckos can breed readily, but females use calcium and energy for repeated clutches, and pairs can injure each other.

Mature males usually have visible hemipenal bulges at the tail base and more obvious preanal pores. Females lack strong bulges and have less visible pores. Juvenile sexing is uncertain.

Sexual maturity often occurs around 12-18 months, but females should not be bred until fully grown, well-conditioned, and usually at least about 45-50 g. Body condition matters more than a single number.

Prepare laying sites, incubation, hatchling enclosures, tiny insects, complete diet, records, and responsible homes before pairing animals. Separate the pair if there is biting, weight loss, hiding stress, or repeated unwanted breeding.

🩺 Common problems

Common problems usually come from overheating, dehydration, constant wetness, poor diet, falls, stress, or breeding females being overworked.

Watch for:

• Stuck shed on toes, eyes, or tail
• Wrinkled skin or sunken eyes
• Weight loss or refusal to eat
• Soft jaw, tremors, or weak grip
• Tail injuries or bite wounds
• Burns from unguarded heat sources
• Nose rub from escape attempts
• Egg binding in females

Check temperature, humidity cycle, diet, supplements, and enclosure security first. Persistent symptoms, injuries, swelling, egg-laying trouble, or neurological signs require a reptile veterinarian.

📌 Conclusion

The gargoyle gecko is hardy, beautiful, and full of personality when its needs are met. It needs height, cover, moderate warmth, a humidity cycle, clean water, complete diet, and secure climbing structure.

It is similar to a crested gecko, but heavier, stronger, and often more territorial. Give it space and respect, and it becomes a long-lived and rewarding New Caledonian gecko.
