Chahoua Gecko / Mossy Prehensile-Tailed Gecko (Mniarogekko chahoua) Care Sheet
The Chahoua Gecko (Mniarogekko chahoua), commonly known as the Mossy Prehensile-Tailed Gecko, is a distinctive arboreal gecko native to New Caledonia.
Its mottled green, brown, grey and cream colouration provides exceptional camouflage against moss-covered bark and lichen. Combined with a robust body, large gripping feet and strongly prehensile tail, this makes the Chahoua one of the most unusual members of the New Caledonian gecko group.
Chahoua Geckos are primarily nocturnal and crepuscular. During daylight they commonly rest against cork, branches or inside elevated retreats, becoming considerably more active after dusk.
Captive-bred individuals can become relatively confident and often tolerate gentle handling, although they remain capable climbers and powerful jumpers.
Unlike some New Caledonian geckos, Chahouas are particularly enthusiastic hunters and generally benefit from a substantial live-invertebrate component alongside a nutritionally complete commercial gecko diet.
Successful husbandry centres on a tall, well-furnished enclosure, moderate temperatures, suitable UVB, high but fluctuating humidity, excellent ventilation, plentiful climbing surfaces and a varied balanced diet.

Taxonomy
The Chahoua Gecko was historically placed within the genus Rhacodactylus and may therefore still be encountered under the older scientific name:
Rhacodactylus chahoua
It is now generally placed in:
Mniarogekko chahoua
Two forms are commonly discussed within the hobby:
- Mainland Chahoua
- Pine Island / Isle of Pines Chahoua
Animals should be accurately labelled where locality or lineage is known.
Responsible breeding should avoid casually mixing established locality lines.
Natural Distribution
Chahoua Geckos are endemic to New Caledonia.
This means they occur naturally nowhere else in the world.
New Caledonia supports several highly distinctive gecko species, including:
- Crested Geckos
- Gargoyle Geckos
- Giant New Caledonian Geckos
- Chahoua Geckos
Established captive breeding is therefore particularly important.
Natural Habitat
Chahoua Geckos inhabit humid forest environments.
They are strongly arboreal and utilise:
- Tree trunks
- Branches
- Hollows
- Bark
- Dense vegetation
- Forest canopy structure
Their mottled colouration allows them to blend remarkably well with bark, moss and lichen.
Captive accommodation should provide abundant vertical structure and visual cover.
Appearance
Chahoua Geckos have a robust appearance compared with many other arboreal geckos.
Typical features include:
- Broad head
- Large eyes
- Powerful limbs
- Adhesive toe pads
- Prehensile tail
- Mottled camouflage pattern
Colouration can include combinations of:
- Green
- Olive
- Brown
- Grey
- Cream
- White
- Reddish tones
Individual appearance can vary significantly according to genetics, locality and firing state.
Prehensile Tail
One of the Chahoua Gecko’s most distinctive adaptations is its strongly prehensile tail.
The tail is used for:
- Balance
- Climbing
- Gripping branches
- Stabilisation when jumping
It should never be used as a handle.
Tail Loss
Chahoua Geckos are capable of dropping their tails.
Unlike Crested Geckos, Chahoua Geckos are capable of regenerating a lost tail to some degree.
However, the regenerated tail may differ from the original in appearance.
Tail loss should still be avoided through calm handling and appropriate enclosure design.
Adult Size
Adults commonly reach approximately:
9–12 inches total length
including the tail.
They are relatively robust geckos and can be surprisingly powerful climbers.
Lifespan
With excellent care, Chahoua Geckos may live approximately:
15–20+ years
Potential owners should plan for a long-term commitment.
Behaviour
Chahoua Geckos are primarily active during the evening and night.
Normal behaviour includes:
- Climbing
- Jumping
- Hunting insects
- Exploring branches
- Resting against bark
- Hiding inside cork
- Feeding on fruit-based foods
During daylight they may remain remarkably motionless and well camouflaged.
Temperament
Captive-bred Chahouas often become relatively manageable.
However, individuals vary considerably.
Some may be:
- Calm
- Curious
- Confident
while others may be:
- Nervous
- Defensive
- Fast
- Reluctant to be handled
Some individuals may bite if frightened or forcibly restrained.
Handling
Allow newly acquired animals time to settle before beginning routine handling.
When handling:
- Allow the gecko to walk between your hands
- Avoid grabbing
- Never pull the tail
- Keep sessions brief initially
- Handle close to a safe surface
Remember that Chahouas can jump unexpectedly.
Enclosure Size
For a single adult:
18" × 18" × 36"
should be regarded as a practical minimum.
Where possible:
24" × 24" × 36"
or larger provides considerably better opportunities for:
- Climbing
- Exercise
- Environmental enrichment
- Thermal gradients
- Dense planting
Larger adults particularly benefit from additional space.
Vertical Space
Height is extremely important.
Chahoua Geckos are strongly arboreal and should be able to move throughout the enclosure without repeatedly descending to the floor.
Provide climbing structure at multiple heights.
Climbing Structure
Suitable furnishings include:
- Cork bark
- Cork tubes
- Natural branches
- Vines
- Bamboo
- Robust live plants
- Artificial foliage
Provide a mixture of:
- Horizontal surfaces
- Vertical surfaces
- Diagonal routes
Chahouas frequently rest against broad vertical cork surfaces.
Branch Diameter
Provide branches of varying thickness.
Some should be sufficiently broad for the gecko to rest comfortably without constantly gripping a narrow perch.
Hides
Provide elevated hiding opportunities.
Suitable options include:
- Cork tubes
- Hollow branches
- Elevated hides
- Dense foliage
Ground-level hides can also be provided but should not be the only retreats available.
Foliage
Dense vegetation provides:
- Security
- Climbing opportunities
- Drinking surfaces
- Humidity gradients
- Visual barriers
Suitable reptile-safe plants can include:
- Pothos
- Ficus
- Schefflera
- Bromeliads
- Philodendron species known to be suitable for vivarium use
Ensure plants are free from pesticides and other harmful chemicals.
Enclosure Security
Chahoua Geckos are strong climbers and can exploit poorly secured openings.
Check:
- Doors
- Ventilation panels
- Cable ports
- Lid fittings
- Door gaps
before introducing the animal.
Substrate
Suitable substrates include:
- Organic topsoil
- Coco fibre
- Orchid bark
- Cypress mulch
- Tropical bioactive mixtures
The substrate should retain some moisture without remaining permanently saturated.
Bioactive Housing
Chahoua Geckos are well suited to properly established bioactive enclosures.
A bioactive setup may contain:
- Live plants
- Natural soil
- Leaf litter
- Springtails
- Suitable isopods
Bioactive housing does not remove the need for:
- Spot cleaning
- Water changes
- Equipment maintenance
- Health monitoring
Temperature
Chahoua Geckos thrive at moderate temperatures.
They should not be maintained continuously at high tropical temperatures.
Day Temperature
General daytime temperatures around:
22–26°C
are appropriate.
Basking Area
A small elevated basking area around:
27–29°C
can be provided.
The gecko must always be able to retreat into cooler shaded areas.
Cool Area
Lower or shaded parts of the enclosure can remain around:
20–23°C
Night Temperature
Night temperatures can generally fall to approximately:
18–22°C
A modest nighttime reduction is beneficial.
Overheating
Chahoua Geckos are vulnerable to excessive heat.
Prolonged temperatures above approximately:
28–30°C
should be avoided.
Particular care is required during summer heatwaves.
Heatwaves
During unusually hot weather:
- Monitor enclosure temperatures closely
- Increase room ventilation
- Reduce unnecessary supplemental heating
- Maintain hydration
- Ensure cool retreats remain available
Do not allow the enclosure to become a sealed heat trap.
Heating
Many homes may require little additional heating for much of the year.
Where supplemental heating is required, use a suitable overhead heat source controlled by an appropriate thermostat.
Avoid heating the entire enclosure uniformly.
UVB
Appropriate low-to-moderate UVB is recommended.
Although Chahoua Geckos are primarily nocturnal, they may receive filtered UV exposure while resting during daylight.
UVB can support:
- Natural vitamin D3 synthesis
- Calcium metabolism
- Natural basking behaviour
- Overall husbandry quality
UV Gradient
The enclosure should provide a gradient allowing the gecko to choose between:
- UV exposure
- Filtered exposure
- Dense shade
- Complete retreat
Dense foliage helps create these choices naturally.
Lighting
Provide a clear day/night cycle.
Approximately:
11–13 hours of daylight
is appropriate depending on season.
Additional LED lighting can support live plants and provide bright daytime illumination.
Night Lighting
The enclosure should become dark at night.
Avoid permanent:
- Red lights
- Blue lights
- Purple lights
Nighttime observation should not involve leaving visible lighting switched on continuously.
Humidity
General humidity around:
60–80%
works well when combined with good ventilation.
Humidity should fluctuate.
The enclosure should not remain saturated continuously.
Humidity Cycle
Humidity will commonly rise after evening misting and then gradually decline as ventilation and daytime warmth dry the enclosure.
This cycle is preferable to constantly wet conditions.
Misting
Mist the enclosure regularly.
In many setups, misting:
Once or twice daily
is appropriate.
The exact frequency depends on:
- Ventilation
- Substrate
- Planting
- Room humidity
- Season
Allow some surfaces to dry between misting periods.
Hydration
Chahoua Geckos commonly lick droplets from:
- Leaves
- Glass
- Branches
- Cork
Regular misting therefore contributes to hydration.
Water Bowl
Fresh drinking water should also be permanently available.
Provide a clean stable water dish and replace the water regularly.
Ventilation
Good airflow is essential.
High humidity combined with stagnant air can contribute to:
- Respiratory problems
- Skin problems
- Mould
- Bacterial growth
Aim for a humid but fresh environment.
Diet
Chahoua Geckos are omnivorous.
A balanced captive diet should include:
- Complete gecko diet
- Live invertebrate prey
Chahouas are often enthusiastic insect hunters.
Complete Gecko Diet
A high-quality nutritionally complete commercial diet formulated for New Caledonian geckos can form the foundation of the captive diet.
Prepare the food according to manufacturer instructions.
Replace uneaten prepared diet before it spoils.
Live Insects
Regular live insects are strongly recommended.
Suitable feeders include:
- Crickets
- Dubia roaches
- Other suitable roaches
- Locusts
- Black soldier fly larvae
- Silkworms
Appropriate insect feeding provides:
- Additional protein
- Hunting enrichment
- Behavioural stimulation
Gut Loading
Feeder insects should be properly gut-loaded before use.
Provide insects with nutritious foods such as:
- Leafy greens
- Vegetables
- Appropriate commercial gut-loading products
Calcium Supplementation
Insects should be appropriately dusted with calcium.
Supplementation should take into account:
- UVB provision
- Complete gecko diet
- Age
- Reproductive status
Avoid unnecessary over-supplementation.
Fruit
Fresh fruit should not replace a nutritionally complete gecko diet.
Commercial complete diets provide a much more predictable balance of:
- Protein
- Calcium
- Vitamins
- Minerals
Small amounts of suitable fresh fruit may occasionally be offered as enrichment, but should not become the dietary foundation.
Juvenile Feeding
Growing juveniles can generally be offered complete gecko diet:
Daily or every other day
with appropriately sized insects several times per week.
Monitor growth and body condition.
Adult Feeding
Adults can generally be offered complete gecko diet approximately:
3–4 times per week
with live insects approximately:
1–2 times per week
depending on:
- Body condition
- Season
- Activity
- Reproductive status
Feeding Ledges
Elevated feeding stations are particularly useful.
They allow the gecko to feed naturally without descending to the enclosure floor.
Obesity
Chahoua Geckos can become overweight.
Monitor:
- Body shape
- Limbs
- Abdomen
- Tail base
Adjust feeding according to individual condition rather than simply providing unlimited food.
Food Enrichment
Useful feeding enrichment includes:
- Controlled insect hunting
- Varying feeding locations
- Elevated feeding cups
- Tong-feeding selected insects
Social Housing
Individual housing is the safest general recommendation.
Chahoua Geckos do not require companionship.
Male Aggression
Adult males should not normally be housed together.
Serious territorial aggression can occur.
Male/Female Housing
Breeding pairs may sometimes be maintained together, but compatibility must be monitored carefully.
Females can suffer:
- Persistent breeding pressure
- Bite injuries
- Stress
- Competition for resources
Separate accommodation should always be available.
Sexing
Mature males generally develop:
- Obvious hemipenal bulges
- Prominent preanal pores
Females lack the pronounced male hemipenal bulges.
Sexing becomes easier as animals mature.
Breeding
Chahoua Geckos can be bred successfully in captivity.
Only healthy mature animals in excellent condition should be paired.
Females require particularly careful attention to:
- Calcium
- Nutrition
- Hydration
- Body condition
- UVB provision
Sexual Maturity
Do not breed females simply because they have reached a particular age.
Body size, weight and overall condition are equally important.
Premature breeding can place unnecessary strain on a developing female.
Egg Laying
Chahoua Geckos are oviparous.
Females generally produce:
2 eggs per clutch
although single eggs can occasionally occur.
Several clutches may be produced during a breeding season.
Nesting
Provide suitable slightly moist laying substrate.
Females may bury eggs in:
- Soil
- Moss
- Substrate
- Concealed planting areas
Bioactive enclosures should be checked carefully during breeding season.
Egg Adhesion
Chahoua eggs may sometimes adhere to surfaces or each other.
Do not forcibly separate firmly attached eggs.
Incubation
Eggs can generally be incubated at approximately:
22–26°C
under stable conditions.
Incubation duration varies substantially with temperature and commonly extends for several months.
Avoid excessively high incubation temperatures.
Eggs should not be rotated after laying.
Hatchlings
Hatchlings require:
- Secure arboreal accommodation
- Fine branches
- Dense foliage
- Appropriate low-level UVB
- Moderate temperatures
- Regular misting
- Tiny feeder insects
- Complete gecko diet
Hatchling Security
Young Chahouas can exploit very small gaps.
Check enclosure security carefully before introducing hatchlings.
Quarantine
All newly acquired reptiles should undergo quarantine.
A minimum of approximately:
90 days
is a sensible starting point.
Monitor:
- Feeding
- Weight
- Faeces
- Skin
- Shedding
- Respiration
- Behaviour
Shedding
Chahoua Geckos normally consume much of their shed skin.
Appropriate hydration and humidity support successful shedding.
Pay particular attention to retained shed around:
- Toes
- Tail
- Limbs
Toe Health
Healthy toe pads are essential for climbing.
Persistent retained shed around the toes can impair grip and circulation.
Inspect feet regularly without unnecessarily disturbing the animal.
Signs of Good Health
A healthy Chahoua Gecko should generally display:
- Clear bright eyes
- Strong grip
- Firm jaw
- Good body condition
- Normal climbing ability
- Regular feeding
- Smooth coordinated movement
- Normal faeces
- Healthy skin and toes
Warning Signs
Seek veterinary advice for:
- Persistent food refusal
- Unexplained weight loss
- Weak grip
- Tremors
- Soft jaw
- Swollen limbs
- Persistent diarrhoea
- Respiratory symptoms
- Severe retained shed
- Abnormal swelling
- Significant lethargy
Common Husbandry Mistakes
Enclosure Too Small
Chahouas are substantial, active arboreal geckos.
Insufficient Climbing Structure
An empty tall enclosure does not provide useful arboreal habitat.
Keeping Them Too Hot
Prolonged excessive temperatures can be dangerous.
Constantly Wet Conditions
Humidity should fluctuate and ventilation must remain good.
No Insects
Chahouas are enthusiastic insect hunters and benefit from regular appropriately supplemented live prey.
Feeding Only Fresh Fruit
A nutritionally complete commercial gecko diet provides a much more balanced foundation.
Poor Calcium Provision
This is particularly important for growing animals and reproductive females.
Housing Incompatible Animals Together
Serious aggression can occur.
Excessive Handling
Even relatively calm individuals benefit from substantial undisturbed time.
Captive-Bred Animals
Captive-bred Chahoua Geckos should be strongly preferred.
Advantages include:
- Known origin
- Established feeding
