Chahoua gecko care starts with the warm, humid canopy of New Caledonia, this gecko’s native home. Mniarogekko chahoua is a large, semi-arboreal gecko that climbs branches and cork bark rather than sitting on the ground.

The setup, temperature, humidity and feeding routine all follow from that native climate. This guide covers the full routine, from enclosure size to health warning signs, and builds on the chahoua gecko species overview.

What Is a Chahoua Gecko

The chahoua gecko, also called the mossy prehensile-tailed gecko, is endemic to New Caledonia, a French territory east of Australia. It lives on the main island of Grande Terre and on the Isle of Pines, in gallery and closed forest up to about 500 m (1,640 ft). It was once grouped with crested and gargoyle geckos in the genus Rhacodactylus.

A 2012 revision by Bauer and colleagues in Zootaxa moved it into its own genus, Mniarogekko, on molecular evidence. The same paper split the far northwest population off as a second species, Mniarogekko jalu.

Brandywine Zoo lists the chahoua gecko’s wild status as Vulnerable, with forest loss the main threat.

Adults reach up to about 10 inches (25 cm) long. Their mottled brown, green or gray pattern blends with moss and bark, giving strong camouflage on a tree trunk.

A prehensile tail lets it grip branches in a way a crested gecko cannot. That closer relative drops its tail and never grows a full one back. Chahoua geckos are nocturnal, resting by day in cork tubes or foliage.

Brandywine Zoo and the Bowling Green State University herpetarium both put lifespan in human care at 20 to 30 years. Wild animals average about 15, and a veterinary source gives a more conservative 15 to 20 years in captivity. Either way this is a long commitment.

New Caledonia Climate and Why It Matters

New Caledonia sits in the South Pacific with a stable tropical climate. Temperatures run roughly 70 to 85°F year round, with humidity holding around 60 to 70% for most of the year. There is no true dry season the way a desert species would face.

That steadiness is the reason chahoua gecko care avoids big swings in heat or moisture. A home enclosure should track the same narrow bands rather than a wide day to night or season to season shift. Sudden drops in humidity, more than sudden heat, tend to cause the most visible husbandry problems in this species.

Chahoua Gecko Setup and Enclosure

Good chahoua gecko care depends more on height than floor space, since this is a climbing species. A single adult needs a minimum of 18 x 18 x 24 inches. Many keepers go larger once a gecko is full grown.

Arboreal lizards and geckos generally need enclosure volume that scales with body length. That differs from the flatter floor area formula used for ground dwelling species. A tall, front opening terrarium works better than a wide, short tub.

Furnish the enclosure with several horizontal and angled branches. Add cork bark tubes for daytime hiding, plus dense live or artificial plants. Plants give cover and help hold humidity steady.

A bioactive substrate of coconut fiber, sphagnum moss and leaf litter holds humidity better than paper alone. Seed it with a springtail cleanup crew to manage waste. Paper towel works fine for a quarantine tub or a young juvenile.

A front opening tall glass terrarium built for arboreal geckos holds humidity better than screen. It also gives easy access for misting and feeding.

Juveniles do better in a smaller space, around 12 x 12 x 18 inches. A large open enclosure can stress a young gecko and make food harder to find.

The full breakdown of sizing, décor and setup steps lives on the chahoua gecko enclosure page.

Chahoua Gecko Temperature and Heating

Chahoua gecko temperature needs mirror New Caledonia’s mild climate, which stays roughly 70 to 85°F year round. Keep the cool end between 70 and 75°F and the warm end between 80 and 85°F. Measure at branch height, not on the glass.

The BGSU herpetarium keeps its animals within the same 70 to 85°F band and states they should never go above 85°F. It reports the geckos prefer 72 to 78°F. Treat the warm end as a ceiling the gecko can visit, not a target for the whole enclosure.

A few degrees of night drop is normal. It rarely needs extra heat, since these geckos tolerate cool nights better than a cold daytime snap.

A low wattage heat mat on the enclosure side, run through a thermostat, usually holds the warm end in range. It also avoids drying the air the way an overhead bulb can. Skip heat rocks and uncontrolled heat lamps, since both can overheat a small enclosure fast.

Use two digital thermometers, one per end. Skip the adhesive strip gauges sold in starter kits, since strip gauges tend to read high.

Chahoua Gecko Humidity and Misting

Chahoua gecko humidity should sit between 60 and 75% most of the day. It can drop somewhat overnight before the morning mist brings it back up.

Mist the enclosure once or twice daily with a handheld sprayer. Leave droplets on leaves and glass without soaking the substrate. Many chahoua geckos drink mainly from these droplets rather than a bowl.

Humidity needs climb further during a shed. Low ambient moisture at that time is a known risk factor for a stuck or incomplete shed, especially around the toes and tail tip.

A digital hygrometer, not a spring dial gauge, gives an accurate reading. Check it at both feeding and misting times.

A combined digital thermometer and hygrometer at mid enclosure height confirms both numbers at a glance.

Chahoua Gecko UVB and Lighting

Chahoua geckos are nocturnal, but low level UVB during dusk and dawn activity still supports natural vitamin D3 production. It works alongside dietary supplements, not instead of them.

A low output, crepuscular focused UVB tube across most of the enclosure gives the gecko a gradient to move through. Run lighting on a 12 hour on, 12 hour off cycle to match a tropical day length.

Replace fluorescent UVB tubes every 9 to 12 months, the interval the Merck Veterinary Manual gives. UV output fades before visible light does. Merck also notes that glass and most clear plastic block UVB, so mount the tube inside or over open mesh.

A low output UVB tube made for crepuscular and nocturnal species avoids the harsher intensity a basking lizard would need.

For the general logic behind picking a bulb, fixture and distance, see the site’s broader heating and UVB guide.

Chahoua Gecko Diet and Supplements

The chahoua gecko diet centers on fruit, not insects, unlike many pet geckos. In the wild they take nectar, pollen, sap and the flesh of overripe fruit, with insects for extra protein.

Captive diets copy this with a powdered meal replacement diet made for frugivorous geckos, mixed with water. Offer this every other day for adults, alongside occasional live insects for enrichment.

Juveniles need more frequent protein for growth. Offer sized insects such as small crickets or Dubia roaches three to four times weekly. Drop to two to three times weekly once the gecko reaches adult size.

Dust every insect with a calcium supplement that has no added phosphorus. Add a separate multivitamin with D3 once or twice a week.

Gut loaded but undusted insects still fall short of a captive gecko’s calcium needs. Skipped supplementation is the leading husbandry cause of metabolic bone disease.

• Adults: powdered fruit diet every other day, insects 2 to 3 times weekly.
• Juveniles: powdered fruit diet daily, insects 3 to 4 times weekly.
• Dust every insect with calcium (no phosphorus) at each feeding.
• Add a D3 multivitamin once or twice weekly, not every feeding.
• Gut load feeder insects about 24 hours before dusting and serving.

A shallow water dish refreshed daily backs up the misting routine, especially in drier homes or during winter heating season.

For gut loading and sizing guidance on the insect half of the diet, see the feeder insects guide.

Chahoua Gecko Handling and Temperament

Chahoua geckos generally tolerate handling better than flightier gecko species. Even so, treat a new arrival as a look rather than touch pet for the first few weeks. Let it settle into its enclosure for one to two weeks before any handling.

Keep early sessions short. Always handle over a solid, low surface rather than open air or a lap, since a fall from height is a common preventable injury.

Unlike a crested gecko, a chahoua does not drop its tail as readily on contact. It also does not regrow a lost tail, according to the BGSU herpetarium. Rough handling can cost a permanent grip tool along with stress or minor skin injury.

Support the whole body rather than gripping the tail. End a session if the gecko vocalizes, gapes, or repeatedly tries to bolt, since those signal it wants to be left alone.

Wash hands before and after handling to avoid transferring soap, lotion or food scent to the gecko’s skin. Short, calm sessions a few times a week build trust faster than long, frequent handling that a nocturnal animal finds stressful during its rest hours.

Cohabitation

Chahoua geckos are solitary and should never be cohabitated as adults, a rule shared with New Caledonian relatives such as the gargoyle gecko.

Housing two geckos together, even a proven pair, risks stress and food competition. Outright fighting can follow outside a deliberate, supervised breeding introduction.

Sources differ on females, though. The BGSU herpetarium houses one male with three or four females and warns only against two males together. The veterinary source above treats every adult as solitary, so the safe default at home is one gecko per enclosure.

Separate juveniles from the same clutch once they show territorial behavior. Females mature at 14 to 18 months. They lay 2 eggs per clutch, three or more clutches a year at roughly 60 day intervals.

BGSU reports only a third to half of eggs hatch. Brandywine Zoo notes that females guard their clutches.

The much larger leachianus gecko, another New Caledonian species, follows the same solitary rule.

Chahoua Gecko Health

Most chahoua gecko health problems trace back to a gap in temperature, humidity or supplementation, not infectious disease. Watch for stuck shed around the toes, tail tip and eye caps, more common when humidity runs low.

A warm soak and gentle misting usually clears a minor stuck shed. Soft or rubbery jaw bones, trouble gripping branches, or a bent spine point toward metabolic bone disease from low calcium or D3.

Bone or joint problems call for an exotics veterinarian, not a home fix. Watch body weight and appetite at every feeding.

A chahoua gecko that refuses food for more than a week or two, especially with lethargy or a sunken tail base, needs a vet exam. Keep the enclosure clean with daily spot cleaning and a regular full substrate change.

Damp, dirty substrate raises the risk of bacterial and fungal skin problems. Any new gecko should pass through quarantine, away from other reptiles, before joining an established collection.

Frequently Asked Questions

Is a chahoua gecko a good pet for a beginner?

A chahoua gecko suits a keeper who has handled at least one arboreal gecko before. Its fruit based diet and humidity needs differ from leopard or crested gecko routines. Reviewing general gecko care basics first helps someone new to the group.

Can chahoua geckos live with crested or gargoyle geckos?

No. Chahoua geckos are solitary and should be housed alone regardless of species. Sharing space with any other gecko risks stress and fighting over food and territory.

Do chahoua geckos need UVB lighting?

A low output UVB tube covering part of the enclosure supports natural vitamin D3 production even in a nocturnal, crepuscular species. It works alongside, not instead of, dietary D3 supplements.

How big does a chahoua gecko enclosure need to be?

An adult needs at minimum 18 x 18 x 24 inches, with height prioritized over floor space. Many keepers use a larger enclosure once the gecko is full grown.

What do chahoua geckos eat besides fruit?

Alongside a powdered fruit based diet, they take sized insects such as crickets or Dubia roaches. Dust insects with calcium at every feeding and a D3 multivitamin once or twice a week.

Why is my chahoua gecko not eating?

A short appetite dip can follow a shed, a new enclosure or cooler weather. Refusal lasting more than a week or two, paired with weight loss or lethargy, warrants a visit to an exotics veterinarian.
