Meet the Chahoua Gecko
If you’ve ever caught a glimpse of a Chahoua Gecko, you know immediately why it earns the nickname “mossy gecko.” Its textured, greenish-brown skin, mottled with darker patches, seems sculpted to disappear into the moss and lichen-covered trees of New Caledonia. It’s the kind of reptile that makes you pause and stare, wondering how something so small can look so perfectly at home in its wild environment. Unlike the more widely known Crested Gecko or the Gargoyle Gecko, the Chahoua has this quiet, understated charm. You don’t notice it bounding across a branch like a showy performer; you notice it because it’s almost invisible—and then, suddenly, it’s there, blinking at you with curious, round eyes.

Native exclusively to the southern islands of New Caledonia, this gecko thrives in humid, tropical forests where moss and bark form a patchwork of natural camouflage. Unlike some of its relatives that are relatively hardy and adapt easily to captivity, Chahoua Geckos carry a certain mystique—they’re specialists. Their evolutionary niche is narrow, and that makes them fascinating but also a bit of a challenge for keepers who want to replicate their natural surroundings. While Crested Geckos seem to flourish in a variety of setups, Chahoua Geckos demand attention to humidity, temperature, and climbing spaces. That’s part of their allure: they’re a gecko for someone willing to get their hands dirty—or at least meticulous about misting schedules.

Behaviorally, these geckos are nocturnal, emerging at twilight to hunt small insects and occasionally sip on fruit or nectar. Observing a Chahoua at night can feel almost meditative. They move deliberately, scanning their surroundings with that slow, thoughtful head tilt that makes you feel they’re pondering the universe—or at least the next cricket. Compared to a more active species like the African Fat-Tailed Gecko, which can be surprisingly bouncy and curious during feeding, the Chahoua’s pace is calm, almost regal. They’re not jumpy, but they are alert. If startled, they’ll freeze mid-branch, blending perfectly into moss or lichen before vanishing from sight entirely.
Physically, the Chahoua is medium-sized for a gecko, generally reaching around 5–7 inches from snout to tail tip, though some males can grow a bit larger. Their skin is not just patterned—it’s textured, almost velvety, with a subtle roughness that adds to the mossy illusion. This isn’t a smooth, shiny gecko like many common pet species; it’s tactile in a way that almost begs to be touched, if you can gain their trust. Males tend to develop more pronounced bumps along the back, while females are slightly rounder and retain the same muted, camouflaged tones. Their eyes are large and round, adapted for excellent night vision, and they seem to have this knowing, observant quality. You’ll often find them watching you from a perch, tilting their heads, as if silently judging your gecko-keeping skills.
One quirky detail enthusiasts love is how these geckos react to misting. Unlike some species that barely notice a spritz, a Chahoua will often pause mid-step, raise its head, and give a little lick of the droplets on its skin or leaves. It’s a small, almost imperceptible behavior, but it’s charming and gives you a glimpse into their sensory world. They rely heavily on humidity—not just for comfort but for shedding. In fact, inadequate humidity can lead to stubborn sheds around toes and tail, a problem not uncommon among New Caledonian geckos in captivity.
For anyone considering them as a pet, the Chahoua Gecko is both rewarding and demanding. They’re not as prolific as the Crested Gecko, meaning they’re less common in the pet trade, but that rarity adds to their mystique. You won’t just be keeping a gecko—you’ll be creating a microcosm of New Caledonia right in your home, complete with moss, vines, and the gentle rhythm of nocturnal life. Watching one explore its carefully crafted environment is a subtle thrill, a reminder that reptiles aren’t just simple creatures; they’re specialists, evolved to perfection for a very particular patch of the world.
In short, the Chahoua Gecko isn’t flashy. It doesn’t leap off branches or demand your attention with dramatic colors. Instead, it blends, observes, and quietly captivates anyone patient enough to watch. Its mossy camouflage, night-hunting habits, and tactile, textured skin make it a standout among gecko enthusiasts. And if you happen to have other New Caledonian geckos like Gargoyle Geckos or Crested Geckos, you’ll notice the subtle differences immediately—the calm, deliberate nature, the mossy patterns, the understated charm that’s unique to the Chahoua. For a reptile lover, it’s a species that invites a deeper kind of appreciation—slow, observant, and endlessly rewarding.
Habitat and Natural Behavior
Rainforest Retreat
The Chahoua Gecko is a true New Caledonian specialist, meaning it’s built for a very specific environment. These geckos thrive in the humid, moss-covered forests of the southern islands, clinging to tree trunks, hiding under bark, or lounging on leafy branches. You’ll rarely spot one in open sunlight—they prefer shaded, protected areas where the temperature remains relatively stable. Think of a forest floor blanketed in moss, ferns swaying gently in the breeze, and the occasional ray of light sneaking through the canopy. That’s the stage where the Chahoua truly comes alive.
Unlike some geckos that adapt to various terrains, the Chahoua has a clear preference: vertical climbing surfaces. Their adhesive toe pads are perfect for scaling bark and moss, and their movements are slow and deliberate, almost meditative. They’re not the darting, hyperactive type you see with African Fat-Tailed Geckos or day-active leopard geckos. Instead, they move with purpose, surveying their surroundings with a kind of quiet curiosity.
Social Dynamics
Chahoua Geckos are primarily solitary creatures, but in their natural habitat, territories sometimes overlap. Observing them in the wild, you’ll notice subtle signals: a tail twitch, a gentle push with the snout, or a slow blink. These gestures communicate dominance or avoidance. They’re nocturnal, emerging at twilight to hunt insects, sip on nectar, and occasionally nibble on soft fruit. The night is when they shine; the forest quiets, and these geckos become the silent orchestrators of their mossy domain.
Even in captivity, they retain these behaviors. Males can be territorial, and multiple males in the same enclosure often lead to stress or dominance displays. Females are generally less confrontational, though they can be assertive during feeding. Watching them interact is like watching a carefully choreographed ballet—subtle, precise, and full of nuance.
- Preferred temperature and humidity ranges: 24–28°C (75–82°F) during the day, 20–24°C (68–75°F) at night, humidity around 60–80%
- Daily activity patterns: Mostly nocturnal, occasional movement at dawn or dusk
- Shelter and climbing preferences: Vertical hides, mossy branches, bark crevices, leaves for cover
Nocturnal Lifestyle
One of the most fascinating aspects of Chahoua behavior is their night activity. They hunt slowly but efficiently, relying on their acute vision and excellent sense of smell. In the wild, insects like crickets, moths, and small beetles make up the bulk of their diet, but they’ll also taste soft fruits when available. Compared to day-active geckos like Gargoyle Geckos, which can be more opportunistic and energetic, the Chahoua’s nighttime foraging is methodical. It’s almost like watching a patient predator in a tiny, green universe.
They also have a surprising level of environmental awareness. Subtle vibrations, faint light changes, or the scent of another gecko trigger immediate responses. They can freeze mid-step, vanish behind a patch of moss, and remain perfectly still until danger—or curiosity—passes. It’s a survival strategy honed over thousands of years, making them experts at camouflage and evasion.
Climbing and Exploration
Chahoua Geckos love vertical space, so their home is never complete without a complex three-dimensional setup. In the wild, they’ll explore tree trunks, moss-laden rocks, and leafy branches. Each movement is calculated, ensuring their camouflage is maintained. In captivity, providing cork bark, driftwood, and live plants mimics this natural complexity and keeps them mentally stimulated. Unlike some other New Caledonian species that will happily stroll across the floor of an enclosure, Chahoua Geckos prefer elevation and cover—it’s literally in their DNA.
- Preferred climbing surfaces: Mossy bark, cork bark, live plants
- Shelter types: Vertical hides, hollow logs, leaf clusters
- Exploration habits: Slow, deliberate, and primarily nocturnal
Appearance and Physical Traits
Mossy Camouflage
One of the first things you notice about a Chahoua Gecko is its incredible camouflage. Their skin is a textured mosaic of greens, browns, and subtle grays that mirrors the moss, lichen, and bark of New Caledonia’s forests. It’s not just color—it’s texture. Run your fingers over a Chahoua’s back (gently, of course), and you’ll feel a fine, velvety roughness that makes them look like a tiny, living piece of the forest. This camouflage isn’t just for show; it’s survival. Predators in the wild often overlook them entirely, mistaking them for a patch of moss on a tree trunk.
Unlike smoother geckos, like Leopard Geckos or even the African Fat-Tailed Gecko, the Chahoua’s skin has a subtle unevenness, with tiny bumps and ridges that break up its outline. Their patterns vary from individual to individual—some have darker blotches concentrated along the spine, while others carry a more uniform mossy hue. This variability makes each Chahoua feel like a miniature work of art, perfectly adapted to its environment.
Size and Build
Chahoua Geckos are medium-sized, typically measuring between 5 and 7 inches from snout to tail. Males often develop slightly larger, robust bodies with pronounced dorsal bumps, giving them a subtle “ridge-backed” appearance, whereas females are slightly rounder but retain the same mossy patterns. Their tails are strong but not overly long, serving both as a fat storage organ and a tool for balance during climbing.
Their eyes are striking—large, round, and perfectly adapted for nocturnal life. The iris often carries a golden-brown hue, speckled with darker flecks, making them look almost like miniature moons embedded in moss. Compared to the wide, alert eyes of a Crested Gecko, the Chahoua’s gaze is steady, observant, almost thoughtful. You can’t help but feel like it’s silently studying you in return.
- Differences between males and females: Males are slightly larger, with more prominent dorsal bumps; females are rounder and more uniformly patterned.
- Comparison to other New Caledonian geckos: Crested Geckos have more flamboyant markings and fringed crests, while Gargoyle Geckos have heavier, more angular heads; Chahouas are subtler and moss-like.
- Eye structure and vision: Large, round eyes with excellent night vision, finely tuned to detect small insects and subtle environmental changes.
Tail Function
A Chahoua’s tail is more than just a balancing tool; it’s a multipurpose organ. Like other geckos, they can drop it when threatened—a process called autotomy—but unlike some species, the regrown tail is often slightly shorter and smoother than the original. The tail also serves as a fat reserve, providing energy during lean periods. Observing a Chahoua wrapping its tail around a branch while climbing or curling it slightly during rest gives you a glimpse into its silent, measured way of interacting with the environment.
Skin Shedding and Care
Shedding is an important aspect of Chahoua health. Their textured skin can make sheds a bit tricky if humidity isn’t ideal. In the wild, they naturally absorb moisture from mist and rain, but in captivity, careful humidity management is critical. Providing a moist hide or regular misting ensures the gecko sheds fully, preventing stuck skin around toes and tail. It’s a small detail, but it tells you just how finely tuned these geckos are to their rainforest homes.
Diet and Feeding Habits
Wild Diet
In the dense, mossy forests of New Caledonia, the Chahoua Gecko has a pretty straightforward diet—but don’t be fooled; it’s precise and effective. These geckos are insectivores at heart, feeding on crickets, small beetles, moths, and other tiny invertebrates. Occasionally, they will sample soft fruits or nectar when available, giving them a tiny splash of sweetness in their diet. Watching a wild Chahoua hunt is fascinating—they move slowly, pausing to assess every movement, every shadow, before striking. It’s not a frantic dash for food like some day-active geckos; it’s deliberate, almost patient stalking.
Interestingly, their feeding habits also tie into their nocturnal lifestyle. Insects that come out at night, like moths and small beetles, make up the bulk of their meals. Some gecko enthusiasts compare them to a tiny, green-toned hunter, a miniature predator perfectly synchronized with the rhythm of the night forest.
Captive Diet
Bringing a Chahoua into captivity means mimicking its wild diet as closely as possible. The staple foods are live insects: crickets, mealworms, roaches, and the occasional waxworm as a treat. To provide variety, some keepers include small amounts of fruit puree or commercially prepared gecko diets designed for New Caledonian species. A critical detail: these geckos are picky. Feed them the same meal every day, and you may notice them ignoring it after a while. Variety keeps them engaged and healthy.
Supplements are key. Calcium and vitamin D3 powders prevent metabolic bone disease—a risk with any insectivorous gecko if proper nutrition isn’t maintained. Unlike Crested Geckos, which can survive on a largely fruit-based diet, Chahouas require more protein from insects, reflecting their wild feeding habits.
- Foods to avoid: Wild-caught insects without proper gut-loading, overly fatty insects, and sticky fruits that may cause digestive issues.
- Supplements and calcium sources: Calcium powder dusted on insects 2–3 times per week, occasional multivitamins as recommended.
- Feeding frequency: Young geckos daily, adults every other day; always remove uneaten insects to prevent stress or injury.
Hunting Behavior
Even in captivity, Chahouas retain their hunting instincts. They’ll stalk crickets slowly, inching closer with calculated precision before snapping them up. Some keepers find it entertaining to watch, noting the subtle head tilts and deliberate pauses that feel almost strategic. It’s a reminder that these geckos aren’t just pets—they’re tiny predators at heart.
Hydration and Fruit Supplementation
While Chahouas primarily rely on moisture from their environment, they do drink water droplets from leaves, glass, or misting. Providing occasional fruit or nectar can supplement hydration and provide enrichment. A small dab of mashed fruit on a leaf often encourages them to explore and lick, stimulating natural behaviors they’d perform in the wild.
Care and Habitat Setup in Captivity
Terrarium Essentials
Keeping a Chahoua Gecko happy in captivity is all about recreating its natural environment as closely as possible. They thrive in vertical space, so a tall terrarium is essential. Think branches, cork bark, and plenty of climbing opportunities. Live plants like pothos, bromeliads, or small ferns provide both shelter and naturalistic humidity control. Hides are a must—moss-covered cork tubes or bark crevices give them that sense of security they’d naturally have in New Caledonia.
Substrate choice matters too. Coconut fiber, orchid bark, or a moss mix work well, holding humidity without becoming soggy. Avoid overly dry or dusty substrates; Chahouas are sensitive to low humidity, and improper substrates can cause shedding problems or stress. The key is layering vertical and horizontal elements, creating a small, complex forest they can explore, climb, and hide in—essentially a three-dimensional playground.
Lighting and Heating
While Chahouas are nocturnal and don’t require intense lighting, a gentle day/night cycle helps maintain their internal rhythm. Ambient light or low-wattage LED bulbs work well. Heating should create a gradient: warmer zones around 28°C (82°F) for basking or digesting, and cooler areas around 24°C (75°F) to give them choice. At night, temperatures can drop slightly to mimic their natural environment, but avoid cold drafts.
Humidity is arguably the most critical factor. Daily misting or a well-placed fogger keeps the enclosure between 60–80% relative humidity. A hygrometer is indispensable—you want to see gentle moisture on leaves and bark, not dripping water everywhere. A moist hide or small water dish adds additional hydration opportunities, encouraging natural drinking behavior.
- Recommended tank mates: Generally, Chahouas prefer a species-only setup, especially males; females can sometimes be kept in pairs. Avoid overly aggressive or territorial geckos.
- Mist schedules and water source options: Light misting 1–2 times daily, with additional moisture in hides; a shallow water dish is optional.
- Handling tips: Chahouas tolerate gentle handling but are best observed more than handled; too much stress can impact feeding and health.
Enrichment and Behavioral Health
A complex terrarium encourages natural behaviors like climbing, hunting, and hiding. Cork bark ramps, moss-covered branches, and varying perches allow them to explore vertically. Some keepers even add small leaf litter layers for insects to crawl under, mimicking hunting opportunities. These subtle touches make a huge difference in reducing stress and keeping Chahouas active and curious.
Regular observation is key. Unlike hyperactive species, Chahouas display their health and mood in subtle ways: a slight curl of the tail, alert head tilts, or activity during nighttime. They don’t shout for attention, so a careful, patient keeper will notice signs that indicate comfort, stress, or illness.
Recreating a Miniature Rainforest
Ultimately, success comes down to replicating the rainforest experience in miniature. Vertical climbing structures, moss, live plants, correct temperature, and humidity create a habitat that supports natural behavior and appearance. Over time, you’ll notice your Chahoua moving with confidence, hunting with precision, and even showing little personality quirks—subtle but unmistakable.
Why the Chahoua Gecko Stands Out
So, what makes the Chahoua Gecko such a gem among reptile enthusiasts? It’s not about flashy colors or extreme antics like some other geckos—it’s about subtle mastery, specialization, and that quiet, mossy charm that seems almost magical. This gecko isn’t just another pet; it’s a little ambassador of New Caledonia’s forests, bringing a piece of that wild, humid world into your home.
First, there’s the camouflage. You can place a Chahoua on a mossy branch, step back, and almost not see it until it moves. That’s a skill in itself. Compared to Crested Geckos, which are colorful and immediately draw attention, or Gargoyle Geckos, with their chunky, angular heads and bold patterns, the Chahoua’s beauty is understated. It’s the kind of beauty that sneaks up on you, grows on you, and never really leaves your mind.
Behaviorally, Chahouas are fascinating. Their nocturnal exploration, deliberate hunting, and subtle social interactions make them endlessly watchable. If you’ve ever observed an African Fat-Tailed Gecko moving energetically across a substrate, you’ll notice the contrast: Chahouas operate with intention, almost meditatively, pausing, scanning, and blending. Every movement seems meaningful. You start to appreciate patience and observation—qualities you might not even realize you have—just by keeping one of these geckos.
Then there’s the challenge aspect. They aren’t “easy” geckos. They demand attention to detail: humidity, vertical space, diet, environmental enrichment. For a dedicated keeper, this is part of the reward. You create an environment that closely mimics their rainforest home, and in return, you get to witness a gecko behaving almost exactly as it would in the wild. Few other species offer this balance of beauty, behavior, and specificity. Crested Geckos are forgiving, yes, but Chahouas reward precision and observation.
Finally, there’s personality. These geckos seem almost introspective, watching from their mossy perch with an air of quiet judgment. Some will explore, others will retreat and observe, but each one has a distinct temperament. The subtle tail curls, the head tilts, the careful stalking of a cricket—these are tiny performances of individuality. In a tank with proper vertical complexity, live plants, and mossy hides, you’ll start to see quirks emerge that feel very much like personalities, not just instinct-driven behaviors.
In summary, the Chahoua Gecko stands out because it embodies a rare combination of beauty, subtlety, and specialist survival strategies. It’s a species that rewards patience, attention, and respect. If you’ve kept other New Caledonian geckos like Gargoyle Geckos or Crested Geckos, you’ll notice the difference immediately—the calm, deliberate movements, the mossy camouflage, the quiet charm. For anyone passionate about reptiles, especially species that demand thoughtful care, the Chahoua is a perfect choice: a living, breathing piece of New Caledonia’s forests, right in your home.
