The New Caledonia Giant Gecko (Rhacodactylus leachianus), often referred to as Leachianus gecko, is one of the largest gecko species, native to the forests of New Caledonia. Known for its impressive size and rugged, rough-textured skin, this gecko is a fascinating and rewarding species to care for. While they require a larger enclosure and more space than smaller gecko species, their calm and gentle temperament makes them a great choice for reptile enthusiasts with experience in keeping larger reptiles.

New Caledonia Giant Gecko Care Guide

Enclosure Size

Juveniles: Minimum 45 x 45 x 60 cm enclosure.

Adults: Minimum 90 x 90 x 120 cm (larger enclosures are always better).

A screened or glass enclosure with good ventilation is ideal. Due to their size, adults need ample climbing space and horizontal room.

Substrate

• Coconut fiber, reptile carpet, or paper towels are ideal.
• Avoid loose substrates that can cause impaction if ingested.

Hides & Climbing

• Provide branches, vines, and live or artificial plants for climbing and creating security.
• One or two hides may be provided, but New Caledonia Giant Geckos are more arboreal, spending their time on vertical surfaces and may not use hides as frequently.

Humidity

• Daytime Humidity: 50-70%
• Nighttime Humidity: 60-80%
• Achieved by misting regularly.
• Mist 1-2 times daily or use an automated misting system to maintain consistent humidity.
• A shallow water dish should also be available for drinking.

Lighting & Temperature

• UVB: Not strictly necessary but beneficial for overall health. Use a low-UVB bulb (2.0 or 5.0) to promote proper calcium absorption.
• Ambient Temperature: 22-26°C.
• Basking Spot: Around 26-30°C.
• Night Drop: No lower than 18°C.

Diet

• Food: Commercial New Caledonia Giant Gecko Diet (CGD), fruit mixes, and live insects such as crickets, silkworms, and dubia roaches.
• Feeding Schedule:
• Juveniles: Every other day.
• Adults: 2-3 times a week.
• CGD should be the primary food source, with insects given as occasional treats.
• Supplementation:
• Supplements are usually not necessary when feeding a good-quality CGD. However, dust insects with calcium without D3 once a week.

Water & Hydration

• Provide misting and a shallow water dish for hydration. These geckos drink water droplets from surfaces, so misting is essential for their hydration.

Handling

• Minimal handling is recommended. New Caledonia Giant Geckos can be easily stressed with frequent handling.
• If handling is necessary, allow the gecko to walk onto your hand rather than grabbing it.

The New Caledonia Giant Gecko is a majestic species that can live for many years with proper care. Their large size, combined with a gentle temperament, makes them an interesting and rewarding pet for reptile enthusiasts who are prepared to meet their needs. With the right environment, they will thrive and show off their impressive size and unique features.
