Common Names: Chahoua Gecko, Mossy Prehensile-Tailed Gecko
Last Updated: August 2026

Chahoua Geckos (Mniarogekko chahoua), also known as Mossy Prehensile-Tailed Geckos, are one of the most distinctive gecko species native to New Caledonia.

Known for their incredible moss and lichen-like camouflage, muscular build, large gripping feet, and powerful prehensile tail, Chahoua Geckos are exceptionally well adapted for life among branches, bark, and dense vegetation.

Chahoua Geckos can be incredibly rewarding animals for keepers prepared to provide appropriate housing, nutrition, lighting, humidity, enrichment, and long-term care. With proper husbandry, they may live approximately 15–20 years or longer.

Let’s break down what you need to help your Chahoua Gecko thrive.

HOUSING

Enclosure Size

Chahoua Geckos are arboreal animals that require a spacious, vertically oriented habitat with enough width, depth, and height to support natural movement.

Rather than focusing solely on a specific set of enclosure dimensions, consider the total usable space available to the animal.

A well-designed Chahoua enclosure should allow the gecko to:

  • Climb vertically
  • Move horizontally and diagonally
  • Jump between surfaces
  • Hide within elevated areas
  • Explore different levels
  • Hunt live prey
  • Thermoregulate
  • Choose between exposed and heavily covered areas

Young Chahoua Geckos can be maintained in appropriately sized grow-out enclosures that make monitoring feeding, hydration, growth, waste, and overall health easier.

As the gecko grows, the enclosure should grow with it.

Adult Chahoua Geckos should be provided with a spacious and well-furnished habitat that allows them to comfortably move throughout the enclosure and display their natural climbing, resting, hiding, hunting, and exploratory behaviors.

Larger, thoughtfully designed enclosures can provide additional opportunities for exercise and enrichment.

Housing Compatibility

We recommend housing Chahoua Geckos individually.

Although Chahoua may sometimes tolerate another animal under specific breeding circumstances, routine cohabitation can introduce competition, territorial behavior, stress, and the potential for injury.

Individual housing also makes it much easier to monitor each gecko’s food intake, body weight, waste, health, and behavior.

Male and female Chahoua Geckos should only be paired intentionally for responsible breeding and should be closely monitored. Separate housing should always be available.

Enclosure Setup & Enrichment

Chahoua Geckos are powerful climbers that naturally interact with bark, branches, hollows, and dense vegetation.

Provide a variety of:

  • Cork bark
  • Cork tubes and hollows
  • Thick branches
  • Horizontal and diagonal climbing surfaces
  • Vines
  • Elevated ledges
  • Live or artificial plants
  • Elevated hiding areas
  • Shaded retreats
  • Multiple levels of foliage and cover

Cork bark is particularly useful because it provides climbing surfaces, textured resting areas, and natural hiding opportunities.

Chahoua are substantial, muscular geckos, so climbing structures should be sturdy and securely mounted.

Foliage and cover should be available throughout the enclosure, but enough open space should remain for the gecko to move comfortably between different areas.

A well-designed enclosure should provide choices rather than one single preferred perch or hiding location.

Naturalistic and bioactive enclosures can provide additional opportunities for exploration and enrichment when properly constructed and maintained.

Substrate

Paper towel is an excellent option for quarantine, hatchlings, newly acquired animals, or whenever closely monitoring waste and health is important.

For established animals, moisture-retentive naturalistic substrates designed for tropical reptiles can be used.

Bioactive setups may incorporate appropriate soil mixtures, coconut fiber, bark, leaf litter, live plants, and cleanup crews.

Avoid substrates containing fertilizers, pesticides, aromatic wood products, or other potentially harmful materials.

TEMPERATURE, LIGHTING & HUMIDITY

Temperature

Chahoua Geckos should have access to a temperature gradient rather than being maintained at one uniform temperature throughout the enclosure.

A good general range is:

Daytime Ambient: Approximately 72–78°F
Warmer Upper Area: Approximately 78–82°F
Cooler Areas: Approximately 70–75°F
Night: Temperatures can fall into the upper 60s°F for healthy animals.

Some modern husbandry practices provide Chahoua with access to a localized basking area around 82–85°F, provided that substantially cooler areas are always available.

For a typical home setup, our priority is providing a gentle temperature gradient and preventing the entire enclosure from becoming excessively warm.

Avoid prolonged temperatures above approximately 85°F, particularly when the gecko cannot retreat to cooler areas.

Depending on your home’s temperature, supplemental heating may not always be necessary.

If supplemental heat is used, it should create a warmer zone rather than heating the entire enclosure uniformly and should be appropriately controlled and monitored.

Use accurate digital thermometers to monitor temperatures throughout the habitat.

Lighting

Although Chahoua Geckos are primarily active during the evening and nighttime hours, they should still experience a consistent day/night cycle.

Approximately 12 hours of light and 12 hours of darkness works well for most setups.

Quality LED lighting can provide visible daylight and support live plant growth within naturalistic and bioactive enclosures.

Avoid red, blue, or other colored nighttime bulbs. Chahoua Geckos should be allowed to experience darkness at night.

UVB

Chahoua Geckos have historically been maintained without supplemental UVB when receiving adequate dietary vitamin D3.

However, modern reptile husbandry increasingly recognizes the potential benefits of providing appropriate low-level UVB to nocturnal and crepuscular reptiles.

For this reason, we recommend providing appropriate low-level UVB when the enclosure and setup allow it.

Chahoua are considered a relatively low-UV species. Appropriate UVB should be provided while maintaining abundant shade and areas of little or no UVB exposure.

UVB strength and placement should be selected based on:

  • Fixture type
  • Bulb output
  • Distance from the animal
  • Enclosure height
  • Screen obstruction
  • Available shade
  • Manufacturer recommendations

The gecko should always be able to move away from UVB exposure.

UVB should not be placed behind glass or acrylic because these materials significantly block UVB radiation.

Humidity

Chahoua Geckos thrive in humid environments but should not be kept constantly wet or stagnant.

A natural humidity cycle is preferable.

A good general target is:

After Misting: Approximately 70–80%
Normal Ambient Period: Approximately 55–70%

Humidity should naturally rise following misting and decrease as the enclosure dries.

Misting frequency will vary depending on your enclosure, ventilation, substrate, plants, room humidity, and local climate.

For many setups, a thorough evening misting is appropriate, with additional misting only when conditions require it.

Constantly saturated substrate, wet surfaces, and stagnant air should be avoided.

Proper ventilation and fresh airflow are just as important as humidity.

Use a reliable digital hygrometer to monitor conditions rather than relying only on a predetermined misting schedule.

FEEDING & WATER

Complete Gecko Diet

Chahoua Geckos are omnivores, consuming both fruit-based foods and animal prey.

This is one area where Chahoua husbandry differs somewhat from that of Crested Geckos.

A high-quality commercially prepared Complete Gecko Diet (CGD) should be an important part of the diet, while live insects should also play a significant role.

Brands such as Pangea and Repashy offer nutritionally complete diets suitable for New Caledonian geckos.

Always prepare complete diets according to the manufacturer’s instructions.

Fruit, baby food, honey, or homemade fruit mixtures should not be relied upon as the primary fruit-based portion of the diet because they do not provide the carefully balanced nutrition of a properly formulated complete gecko diet.

Insects

Live insects are an especially important component of Chahoua Gecko nutrition and should not simply be considered an occasional treat.

Chahoua typically have a strong prey drive, particularly while growing.

Good feeder options include:

  • Crickets
  • Dubia roaches
  • Discoid roaches
  • Other appropriately sized and nutritionally suitable feeder insects

Young, growing Chahoua may accept live insects very frequently, while healthy adults can generally be offered insects multiple times per week depending on body condition, activity, reproductive status, and the rest of their diet.

Rather than focusing on one rigid feeding ratio, we recommend providing a varied diet and adjusting feeding frequency according to the individual animal’s age, body condition, growth, reproductive status, and appetite.

Feeder insects should be properly gut-loaded before feeding.

Appropriate calcium and vitamin supplementation should also be used according to the animal’s overall diet and whether UVB is being provided.

High-fat feeders such as waxworms should be considered occasional treats rather than staple insects.

Water

A dish of clean, fresh water should always be available.

Chahoua Geckos will also frequently drink droplets from leaves, branches, cork bark, and enclosure surfaces following misting.

Clean the water dish and replace the water regularly.

HANDLING & INTERACTION

Chahoua Geckos can become remarkably confident and interactive animals, but individual temperament varies.

Some animals may become very comfortable with routine interaction while others remain more cautious.

Give New Geckos Time to Settle

After bringing a new Chahoua Gecko home, allow it time to acclimate before beginning regular handling.

The gecko should have an opportunity to establish normal feeding, drinking, and behavior within its new environment first.

Approach Slowly

Use slow and deliberate movements.

Whenever possible, allow the gecko to step onto your hand rather than grabbing it from above.

Support the Gecko

Chahoua Geckos have strong feet and a muscular prehensile tail.

Support the body and allow the gecko to move naturally from hand to hand.

They are capable climbers and can jump unexpectedly, so handling should take place above a secure surface and away from dangerous heights.

Be Careful With the Tail

Never pick up, pull, or restrain a Chahoua Gecko by its tail.

Their powerful prehensile tail is an important part of climbing and balance.

Even though Chahoua are generally less prone to dropping their tails than some other New Caledonian geckos, unnecessary pulling or restraint should always be avoided.

Keep Handling Sessions Controlled

Begin with short handling sessions and gradually increase interaction as the gecko becomes comfortable.

If the animal repeatedly attempts to escape, bites, vocalizes, breathes heavily, or otherwise displays signs of significant stress, return it to the enclosure and try again another time.

Handling should be a controlled and positive experience rather than something the animal is forced to tolerate.

Keep Other Pets Away

Never allow your Chahoua Gecko to interact directly with cats, dogs, or other household pets.

Even seemingly calm interactions can result in serious injury.

ROUTINE HEALTH & MONITORING

Learning what is normal for your individual Chahoua Gecko makes it easier to recognize potential health concerns early.

Regularly monitor:

  • Body weight and body condition
  • Appetite
  • Insect feeding response
  • Feces and urates
  • Activity level
  • Eyes and skin
  • Toes and feet
  • Jaw and bone structure
  • Tail condition
  • Shedding
  • Hydration
  • Breathing
  • Changes in behavior

A small digital gram scale is an excellent tool for tracking growth and adult body condition.

Shedding

Healthy Chahoua Geckos periodically shed their skin and may consume the shed afterward.

Proper hydration, humidity cycles, and access to textured surfaces help support normal shedding.

Check the toes, feet, and tail area for retained shed.

When to Contact a Veterinarian

Contact a veterinarian experienced with reptiles if your gecko develops concerning symptoms such as:

  • Significant or unexplained weight loss
  • Persistent refusal to eat combined with weight loss or other symptoms
  • Swelling
  • Abnormal jaw or limb structure
  • Persistent retained shed
  • Difficulty breathing
  • Discharge from the eyes, nose, or mouth
  • Significant lethargy or weakness
  • Persistent abnormal feces
  • Injury
  • Neurological symptoms
  • Any sudden or significant change in normal behavior

Routine wellness examinations with a qualified reptile veterinarian can also be an important part of preventative care.

FINAL THOUGHTS

Chahoua Geckos are remarkable animals combining incredible natural camouflage, powerful climbing ability, fascinating feeding behavior, and individual personalities.

Responsible ownership begins with understanding and providing for their specific needs.

A spacious and complex habitat, sturdy climbing structures, foliage, appropriate lighting, temperature and humidity cycles, a varied omnivorous diet, fresh water, enrichment, and regular health monitoring all help create an environment where a Chahoua Gecko can display more of its natural behaviors and thrive.

Reptile husbandry continues to evolve as we learn more about animal welfare, nutrition, lighting, and natural behavior. We encourage every keeper to continue learning and to adjust their husbandry as better information becomes available.

At Guardians of the Geckos, our goal isn’t simply to produce incredible geckos. We want every animal we produce to go into a home prepared to provide excellent lifelong care.

Passion. Innovation. Genetics.
