Why Choose a Leachianus Gecko?
Leachianus Geckos are a standout choice for reptile enthusiasts looking for a unique and interactive pet. Their large size, vocalizations, and distinctive appearance make them a captivating addition to any collection. However, their care requirements and temperament variability mean they are not ideal for beginners.
These geckos are perfect for those who enjoy observing their pets as much as handling them. Their nocturnal nature and arboreal lifestyle make them fascinating to watch, especially in a well-decorated enclosure.
Handling and Temperament
Leachianus Geckos are known for their unpredictable temperaments. While some individuals are calm and enjoy human interaction, others can be defensive and even aggressive. This variability is one of the biggest challenges of owning a Leachie.
Personality Variations
- Calm and Docile: Some Leachianus Geckos are incredibly gentle and enjoy being handled. They may sit comfortably in your hand or even crawl onto your shoulder.
- Feisty and Defensive: Others are more territorial and may bite or vocalize when approached. Their powerful jaws can deliver a painful bite, so caution is advised.
Handling Tips
- Start Slow: Allow your gecko to acclimate to its new environment before attempting to handle it.
- Be Gentle: Always handle your Leachie with care, supporting its body and avoiding sudden movements.
- Respect Their Space: If your gecko shows signs of stress (hissing, biting, or trying to escape), give it time to calm down before trying again.
Vocalizations
One of the most unique aspects of Leachianus Geckos is their ability to vocalize. They can produce a range of sounds, from chirps to growls, which adds to their charm. However, these vocalizations are often a sign of stress or discomfort, so it’s important to pay attention to your gecko’s behavior.
Care and Maintenance
Leachianus Geckos require a specialized care routine to thrive. While their needs are similar to those of Crested Geckos, they are more demanding due to their size and sensitivity.
Enclosure Setup
- Size: A vertically oriented enclosure is essential, as Leachies are arboreal. A 20-30 gallon tank is suitable for juveniles, while adults need at least a 40-50 gallon enclosure.
- Climbing Space: Provide plenty of branches, vines, and foliage for climbing and hiding.
- Substrate: Use coconut fiber, reptile carpet, or paper towels to maintain humidity. Avoid loose substrates that could cause impaction.
- Hiding Spots: Include multiple hiding spots to help your gecko feel secure.
Humidity and Temperature
- Humidity: Maintain humidity levels between 60-80%. Mist the enclosure twice daily to achieve this.
- Temperature: Keep the enclosure at room temperature (72-78°F). Avoid temperatures above 80°F, as overheating can be fatal.
Feeding
- Diet: Leachianus Geckos thrive on a diet of pre-packaged gecko food, such as Pangea or Repashy. These diets are nutritionally complete and easy to prepare.
- Supplements: Occasionally offer live insects like crickets or dubia roaches for variety.
- Feeding Schedule: Feed adults every other day, adjusting portion sizes based on their appetite.
Lighting
Leachianus Geckos do not require UVB lighting if their diet is properly supplemented. However, low-level UVB lighting can benefit their overall health.

Health and Durability
Leachianus Geckos are generally hardy, but they are sensitive to environmental changes and stress. Proper care is essential to ensure their long-term health.
Common Health Issues
- Respiratory Infections: Caused by excessive humidity or poor ventilation.
- Dehydration: Occurs if humidity levels are too low.
- Tail Loss: While rare, Leachies can drop their tails if severely stressed. However, their tails can still grow back.
Preventative Care
- Maintain Proper Conditions: Regularly monitor humidity and temperature levels.
- Handle with Care: Avoid overhandling, especially with defensive individuals.
- Provide a Balanced Diet: Ensure your gecko receives all necessary nutrients.
With proper care, Leachianus Geckos can live 20-30 years, making them a long-term commitment.
Availability and Cost
Leachianus Geckos are rare and expensive, which can make them difficult to acquire.
Where to Buy
- Breeders: The best option, as breeders can provide healthy, well-cared-for geckos.
- Reptile Expos: A great place to meet breeders and see a variety of geckos in person.
- Pet Stores: Less ideal, as most stores do not carry Leachianus Geckos.
Cost
- Gecko Price: $300 to $500 for standard morphs, with rare morphs costing thousands of dollars.
