Leachianus Gecko (Rhacodactylus leachianus) - General Care Guide

Leachianus Geckos, scientifically known as Rhacodactylus leachianus, are large, arboreal geckos native to New Caledonia. Also known as Leach's Giant Gecko, they are considered one of the largest species of geckos in the world. To provide optimal care for Leachianus Geckos, it is important to understand their specific requirements in terms of housing, temperature, humidity, diet, and handling. Here is a detailed care guide for Leachianus Geckos, based on information from multiple reliable sources:


  • Baby Leachianus Housing: Baby Leachianus Geckos can be housed in a temporary enclosure like a plastic shoebox container with adequate ventilation. Ensure the container is escape-proof and provides enough space for the gecko to move around comfortably. However, they grow quickly, so plan to upgrade their enclosure as they grow.
  • Large Leachianus Housing: Adult Leachianus Geckos require larger enclosures. A minimum enclosure size of 18x18x24 inches (45x45x60 cm) is recommended, but for larger individuals, such as adults or those with more active behavior, a size of 18x18x36 inches (45x45x91 cm) or larger is preferable. Providing ample vertical space for climbing is essential.


  • Temperature: Maintain a temperature range between 75-82 degrees Fahrenheit (24-28 degrees Celsius) during the day, with a slight drop at night. Use a combination of ambient room temperature and supplemental heating if necessary.
  • Lighting: Leachianus Geckos do not require UVB lighting but benefit from a natural day-night cycle. Ambient room lighting is usually sufficient.
  • Humidity: Leachianus Geckos require higher humidity levels, around 60%-80%. Mist the enclosure heavily at least once or twice daily and provide a humid hide to help maintain proper humidity levels. Monitor humidity using a hygrometer and adjust misting frequency as needed.


  • Diet: Leachianus Geckos are primarily insectivorous. Offer a varied diet of appropriately sized live insects, such as crickets, roaches, silkworms, and superworms. Gut-load insects with nutritious food before feeding.
  • Supplementing: Dust the insects with a calcium supplement powder and a multivitamin supplement before offering them to your Leachianus Gecko. Calcium and vitamin supplementation is crucial for their overall health.
  • Water: Provide a shallow water dish filled with fresh water at all times. Leachianus Geckos may drink from the dish or lick droplets from leaves and enclosure surfaces. Change the water regularly to maintain cleanliness.


  • Handling: Leachianus Geckos are generally more tolerant of handling compared to other gecko species. However, it is important to approach them gently and with caution. Allow your gecko time to acclimate to its new environment before attempting any handling.
  • Warning on Cage Aggressiveness: Leachianus Geckos, especially males, can display territorial behavior and aggression towards other geckos. It is recommended to house them individually to avoid potential conflicts and injuries.
  • Handling Guidelines: When handling your Leachianus Gecko, support its body and tail properly. Avoid squeezing or grasping the gecko too tightly. Keep handling sessions brief and observe the gecko's behavior for any signs of stress or discomfort. If the gecko becomes agitated or shows signs of aggression, gently return it to its enclosure.
