Crested Gecko: Rhacodactylus ciliatus

The Crested Gecko is native to New Caledonia . It is perhaps the best pet reptile to be “discovered” in the past century. Previously thought to be extinct, numerous Crested Geckos were found happily living on several islands off of New Caledonia as well as on the mainland in the 1980's. Since their rediscovery their capture and import has been ended. Not only comical and beautiful, these little guys are extremely hardy and easy to care for! They also acclimate well to regular gentle handling and some even appear to enjoy being taken out of their cages and held.

Average Size

7 to 9 inches (half of this being its tail)

Life Span

Over 15 years if properly cared for.


Perhaps the best part of keeping Crested Geckos is that they do not need to be fed live insects. 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. This diet, Crested Gecko Meal Replacement Powder (MRP), is mixed with water to make a nutritionally complete food that Crested Geckos 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 and gutloaded, mineral powder dusted crickets. The MRP powder is both easier to use and produces better results. I feed only the TRex MRP to all of my geckos.


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 Crested Gecko is nocturnal, feeding at night time just before lights out is recommended. If feeding insects with MRP, insects should be offered on alternating nights with MRP. Mealworms should be fed sparingly as they are very fibrous and can cause impactions. 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.



Crested Geckos 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.


Since the Crested Gecko is arboreal (lives in the trees) it strongly prefers a cage that is taller than it is long. Young geckos can be kept in small (1-2 gallon) cages until they are about 10 grams. Housing that is too large (ie 30 gallon tank for a hatchling) should be avoided when keeping very young geckos as they may have trouble finding their food. A single adult gecko can be housed in a 20 gallon long aquarium set up on its long end, or in a screen cage measuring 1 foot long X 1 foot deep X 2 feet high. Multiple males should not be housed together as they will fight to the death. Females can be housed together, though some may have personality differences and quarrel. If this occurs they should be permanently seperated- females that take a dislike to each other rarely get over it. Overall the females seem to enjoy each others company, often being found curled up under leaves together. If males and females are housed together mating and egg laying is almost guaranteed. Juveniles should be kept in like sized groups as larger ones can and will bully smaller ones, preventing their access to food.


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.


Crested Geckos love their vertical space. Bamboo poles and vertically placed cork flats will make your geckos very happy. They are also especially fond of plants, such as Pothos (which is extremely hardy), both live and fake. The more hiding places that you give your gecko the less stressed it will be, and consequently healthier. If you are going for a sterile, easy to clean set up egg crates make excellent, though not pretty, hiding places and maximize surface areas for your geckos.

Grooming and Hygiene

Cresteds 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 transmission of Salmonella and other infectious diseases.


Crested Geckos prefer to be kept at room temperature (from 65- 80 degrees F). They experience stress at temperatures over 85 or under 65 degrees.


As a nocturnal species your Crested Gecko 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. If the house is extremely cool a 50 watt basking lamp may be used to provide a warm spot.


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 Crested Gecko 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.

Normal Behavior and Interaction

Crested Geckos 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. They seem to enjoy each others company greatly and often sleep together during the day. At night it is not uncommon to hear the rustle of leaves during little tussles as well as growls, squeaks, barks and yips as they talk to each other in the same cage, and to geckos in other cages. Cresteds are normally amenable to handling with a little bit of patience and work. Very young animals (under three months) should be handled very little, if at all. Older juveniles and adults can be handled for as much as they tolerate, which will vary from individual to individual; some never really settle down, while others are happy to sit on a shoulder or desk for hours at a time.

Two warnings should be heeded, however. First, Crested Geckos love to jump! 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 Crested Gecko drops its tail it will never grow back (unlike many other species). These stumpy Cresteds suffer no long term negative effects, but never regain their beautiful, prehensile tails. Rough handling and overly stressing your gecko should be avoided if you want your pet to retain its caudal appendage.

Common Health Issues and Red Flags

Mites: Although mostly uncommon in a private collection, mites are a possible complication. They will most likely be noticed first around the eyes or the corners of the mouth as little round, black/brown creepy creatures. They can be treated by many commercial products available at a local pet shop or by a veterinary strength solution available from your veterinarian. Be sure to follow the directions on the product. Treatment of mites usually takes close to a month of continuous care as eggs can hatch daily and must be taken care of' ASAP. These little bugs have an extraordinary reproductive rate. If you have more than one infested reptile, take extra precautions not to transfer the mites from one to another.

Impaction: If you are keeping your Crested Gecko on a natural substrate and feeding insects it will likely ingest some of the substrate at each feeding. In small quantities this will not be overly harmful, but in large quantities your gecko may become impacted with substrate in its intestine, a condition that is almost invariably fatal. Prompt treatment by an exotics vet may save your pets life.

Calcium Deficiency - Without adequate calcium in your Crested's diet, aside from a slow growth rate, you will more than likely encounter Metabolic Bone Disease. The first symptom usually noticed is uncontrolled twitching of the geckos toes or legs, a floppy jaw, or a kinked tail. This can be a fatal disease if not treated promptly. If this problem occurs, I suggest raising the amount of calcium in the gecko's diet immediately. Take your gecko to a good exotics vet who can prescribe a calcium supplement. This is most common in breeding females.

Internal Parasites - A common internal parasite in Crested Gecko's is Entameoba invadens , which needs to be diagnosed and treated by a veterinarian. If left untreated too long it can be fatal. Other internal parasites are also possible in Cresteds, and can be diagnosed by your veterinarian via a stool sample.

If you notice any of these signs, please contact your exotic animal veterinarian.
