Mossy Prehensile Tailed Gecko - Rhacodactylus chahoua

The Mossy Prehensile Tail Gecko, commonly known as the chahoua, is native to New Caledonia. There are two locales, the Mainland and the Pine Isle. The Pine Isle is more colorful, while the Mainland is larger and slightly duller. The Chahoua is the second largest Rhacodactylus gecko, smaller than only Rhacodactylus leachianus. They are most infamous for their propensity to roll into a ball when they are threatened. This large, gentle gecko species makes a good pet for those with some previous reptile experience. While very hardy they are slightly less durable than their cousins the Crested Gecko and Gargoyle Gecko. They are also harder to breed than some of the other Rhacodactylus geckos. All in all, however, they are an interesting species which, while relatively easy in their care, is still a challenge for even experienced keepers.


Average Size: Variable, up to 10 inches.

Life Span: Well over 15 years if properly cared for.

Diet: Perhaps the best part of keeping Chahouas is that they do not need to be fed live prey. They are an omnivorous species, which in the wild eats both insects and rotting fruits and flowers. In captivity they can be fed an excellent powdered diet produced by TRex reptile products. While there is no diet specific to the Chahoua, they do quite well on the diet developed for their cousin, the Gargoyle Gecko. This diet, Gargoyle Gecko Meal Replacement Powder (MRP), is mixed with water to make a nutritionally complete food that Chahouas just love! Alternatively, a fruit and meat baby food, vitamin/ mineral supplement/ honey/ spirulina/ bee pollen mix can be used in conjunction with insects such as mealworms, waxworms and gutloaded, mineral powder dusted crickets. The MRP powder is easier to use, but better growth rates are shown when live insects are fed.

Feeding: If feeding the TRex MRP solely most keepers feed either daily or every other day, leaving the dish in there for a second night. Since the Chahoua is nocturnal, feeding at night time just before lights out is recommended. If feeding live prey with MRP, insects and MRP should be fed on alternating nights. Crickets should not be larger than the width of the head of the smallest gecko in the tank. All crickets should be properly gutloaded and dusted with mineral powder (no phosphorous)/ vitamin supplement before feeding. Some Chahouas may also eat mouse pinks, but these should not be fed more than once weekly.

Housing: Chahouas can be housed in either screen or glass/ plexi enclosures. In drier areas it is recommended that glass/ plexi cages be used to provide adequate humidity. In areas with higher humidity screen cages are excellent for providing adequate ventilation. Cages should be permitted to dry out entirely during the day following a heavy night time misting. Housing should be chosen to permit this to occur, otherwise problems with molding of the housing from too high of humidity can occur, or the animals can have retained shed due to low humidity

Size: Since the Chahoua is arboreal (lives in the trees) it strongly prefers a cage that is taller than it is long. Multiple females can be safely housed together, but multiple males should never be housed together as they will fight fiercely. Care should be taken any time multiple females, or a male and females, are housed together that no one animal is being bullied or prevented from feeding. A single adult can be housed in a 29 gallon tank stood up on its long axis. One male and several females can be housed in an enclosure measuring 24 inches long X 24 inches deep X 36 inches tall.

Substrate: Paper towels or cage liners are by far the easiest substrate to use, though not very aesthetically pleasing. If males and females are housed together with the intent of breeding they will make finding the eggs much simpler, however. For a more pleasing set up cocofiber can be used as a substrate and planted nicely. Caution must be used if feeding insects on cocofiber however, as the geckos may ingest it when feeding. Reptile barks can also provide a nice substrate, though they carry the same risk of ingestion. NEVER use pine/ cedar chips intended for small mammals as they can make your gecko very, very ill.

Habitat: Chahouas love their vertical space. Bamboo poles, branches and vertically placed cork flats will make your geckos very happy. They are also especially fond of plants, such as Mother- in Law Plants, Pothos (which is extremely hardy) and anything else hardy enough to support their weight, both live and fake. The more hiding places that you give your gecko the less stressed it will be, and consequently healthier. Cork curls also make excellent hides and can be siliconed in place on the sides of the enclosure. In a more sterile enclosure egg crates can be used to provide many hiding places at relatively low cost and thrown away when soiled.

Grooming and Hygiene: Chahouas require very little actual grooming. Most important is to maintain adequate humidity to prevent retained sheds. In the case of a retained shed the gecko can be carefully soaked in warm water, or placed in a small plastic container (with holes punched) with damp paper towels for 30 minutes twice daily until the shed is removed. Always wash your hands before and after touching your gecko or habitat contents to help prevent Salmonella and other infectious diseases

Temperature: Chahouas prefer to be kept at room temperature (from 65 - 80 degrees F). They experience stress at temperatures over 85 or under 65 degrees. It is advisable to provide a 75 watt light bulb for your gecko to bask under should it choose.

Lighting: As a nocturnal species your Chahouas will likely not come out when the lights are on, nor do they have any lighting requirements. If you are going to plant your tank a full spectrum bulb is recommended

Water: Provide a constant supply of clean, fresh, filtered, chlorine-free water in a shallow bowl that cannot be tipped over. Using a plant mister, mist your Chahouas heavily twice daily. They will eagerly lap the water off of the surfaces in their enclosure, and the misting will provide much needed humidity.

Habitat Maintenance: Change water in the bowl daily; remove feces daily. Thoroughly clean the tank at least once a week.

Recommended Supplies:

  • Misting bottle
  • Water dish
  • Food dish
  • Meal Replacement Powder
  • Live or fake plants 
  • Cork bark/ bamboo/ branches
  • Tank/ screen enclosure with secure lid/ door
  • Light, if desired
  • Paper towels or Cocofiber for substrate 
Normal Behavior and Interaction: Chahouas are a nocturnal species that will spend all day sleeping. Once they get up in the evening they are amusing to watch wandering around their cage. At night it is not uncommon to hear growls, squeaks, barks and yips as they talk to each other in the same cage, and to geckos in other cages. Chahouas are known for being very easy to handle, though some may roll up into a ball if they feel threatened. They tend to be less flighty than Crested Geckos, and will sit calmly for gentle handling.

Two warnings should be heeded, however. First, Rhacodactylus geckos are known for their ability to take a leap! Animals that are not accustomed to handling should be kept close to the ground until they have lost their desire for flight. Second, if your Chahoua drops its tail it will never look the same again, though it will grow back. Rough handling and overly stressing your gecko should be avoided if you want your pet to retain its caudal appendage.

Signs of a Healthy Pet:

  • Active and alert
  • Healthy skin
  • Clear eyes
Eats regularly
Clear nose and vent 

Common Health Issues and Red Flags: 

  • Weight loss or decreased appetite
  • Mucus in mouth or nose
  • Swelling
  • Lethargy
  • Bumps, sores, or abrasions on skin
  • Labored breathing
  • Paralysis of limbs or tail
  • Abnormal feces 
  • Inability to climb
  • Kinked tail
  • Floppy jaw

If you notice any of these signs, please contact your exotic animal veterinarian.
As with all pets in this category, it is important that you find a veterinarian that practices in EXOTICS – this is critical. The typical small animal practitioner may not have sufficient knowledge in this area. Even this guide is general in nature and should not be used to diagnose your pet.

I would like to Thank Genevieve LaFerriere for writing this caresheet. She breeds and sells geckos, visit her website:
