Crested geckos have gained popularity as captivating pets in recent years. Their unique physical features and intriguing behaviors make them a favorite among reptile enthusiasts. In this blog, we will delve into the world of crested geckos, uncovering interesting facts and trivia about these remarkable creatures.

Origins and Discovery:

Native to the lush rainforests of New Caledonia, crested geckos remained elusive until their rediscovery in the late 20th century. This serendipitous discovery sparked a wave of fascination with these once-thought-lost reptiles.

Crested geckos are believed to have evolved to thrive in the tree canopies of New Caledonia, adapting to an arboreal lifestyle. Their unique physical characteristics, such as their prehensile tail and specialized toe pads, allow them to climb and cling to vertical surfaces with ease.

Physical Characteristics:


Crested geckos are instantly recognizable by their crest, a row of soft spines that extends from above their eyes to the base of their tail. The crest serves various purposes, including communication, thermoregulation, and even acting as a defense mechanism. When threatened, they can flatten their bodies and raise their crest to appear larger and more intimidating.

One of the most intriguing aspects of crested geckos is their ability to change their skin color. They possess a range of vibrant colors and patterns, and their skin can shift between shades depending on factors such as temperature, mood, and camouflage needs. This color-changing ability adds to their allure and makes each individual gecko unique.

Behavior and Personality:


Crested geckos are primarily nocturnal, meaning they are most active during the night. This behavior is an adaptation to their natural habitat, where they avoid competition and predation by staying hidden during the day. Their arboreal nature enables them to navigate their environment with ease, displaying impressive climbing abilities and jumping from branch to branch.

While crested geckos are generally solitary creatures, they do exhibit certain social behaviors. Males, in particular, may display territorial behavior and vocalize to establish dominance or attract a mate. Their vocalizations range from chirping and clicking sounds to soft squeaks.

Diet and Feeding Habits:


In the wild, crested geckos primarily feed on fruits, nectar, and insects. As pets, they require a balanced diet consisting of specialized crested gecko food, which is a commercially available powdered mix. This food can be mixed with water to form a paste, providing the necessary nutrients, vitamins, and minerals.

Supplementing their diet with fresh fruit is also recommended to provide variety and additional nutrients. Mashed bananas, pureed baby food, and other soft fruits are popular choices. Additionally, offering occasional live insects, such as small crickets or mealworms, can satisfy their natural instinct to hunt and serve as a protein source.

Reproduction and Lifespan:


Distinguishing between male and female crested geckos is relatively easy due to sexual dimorphism. Males typically have larger crests and exhibit bulges at the base of their tails, which house their hemipenes. Females, on the other hand, have smaller crests and lack these bulges.

Breeding crested geckos requires specific conditions, including proper temperature and humidity levels. Females lay a pair of eggs, which are usually attached to vertical surfaces or concealed within moist hiding spots. The eggs undergo an incubation period that typically lasts around 60-90 days, depending on the temperature. Once the eggs hatch, adorable hatchlings emerge, ready to embark on their own journeys.

With proper care, crested geckos can live for 15 to 20 years in captivity. Their lifespan is influenced by various factors, including genetics, diet, environmental conditions, and overall health. Providing a suitable habitat, a balanced diet, and regular veterinary check-ups are essential for ensuring their longevity.

Care and Enclosure Setup:

Creating an ideal habitat for crested geckos is crucial for their well-being. A suitable terrarium should provide ample space for climbing, as they are arboreal creatures that require vertical space to exercise and explore. The enclosure should be equipped with sturdy branches, vines, and foliage to mimic their natural environment and offer hiding spots.

Choosing the right substrate is important to maintain proper hygiene and facilitate easy cleaning. Substrates such as coconut fiber, orchid bark, or reptile carpet are commonly used, as they are safe and easy to maintain.

Maintaining appropriate temperature and humidity levels is vital for the health of your crested gecko. The temperature should range between 72-78°F (22-26°C) during the day, with a slight drop at night. It’s recommended to use a digital thermometer to monitor the temperature accurately. Humidity levels should be kept between 60% and 80%, mimicking the tropical conditions of their native habitat. Regular misting of the enclosure and using a hygrometer to monitor humidity levels can help create a suitable environment.

Crested geckos do not require UVB lighting since they are primarily nocturnal. However, providing a low-wattage heat source, such as an under-tank heater or ceramic heat emitter, can help maintain stable temperatures in their enclosure.

Regular cleaning and maintenance of the enclosure are necessary to prevent the growth of harmful bacteria. Spot-cleaning feces and uneaten food daily, along with a thorough cleaning and disinfection of the enclosure every few weeks, will ensure a clean and healthy environment for your gecko.

Health Concerns and Common Issues:

Crested geckos are generally hardy reptiles, but they can be susceptible to certain health problems. Metabolic bone disease (MBD) is a common concern and occurs when there is a deficiency of calcium and vitamin D3 in their diet. Providing a balanced diet with appropriate supplementation is essential to prevent MBD.

Shedding difficulties can also occur if the humidity levels are not adequately maintained. Ensuring proper hydration and providing a humid hide, such as a small container with damp moss, can assist in the shedding process.

Parasite infestations, such as mites or internal parasites, can affect crested geckos. Regular observation of your gecko’s behavior, appetite, and appearance is crucial in detecting any signs of illness. If you notice any abnormalities or suspect health issues, it is important to consult a reptile veterinarian with experience in treating crested geckos.

Fun Facts and Trivia:

  • Did you know that crested geckos are one of the few gecko species that have eyelids? This unique adaptation helps protect their eyes from debris and maintain their vision.
  • Contrary to popular belief, crested geckos cannot regenerate their tails like some other reptiles. However, if their tail is dropped due to stress or predation, it will not cause harm to the gecko, and a small, non-functional tail stub will regrow in its place.
  • Crested geckos possess a unique ability called autotomy, allowing them to detach their tails when threatened. This serves as a distraction to predators, giving the gecko a chance to escape.
  • Crested geckos have a remarkable ability to cling to surfaces using specialized toe pads. These pads contain tiny hair-like structures called setae, which create an adhesive force that allows them to stick to vertical or even upside-down surfaces with ease.
  • While they are primarily nocturnal, crested geckos may exhibit some activity during the day, especially during feeding or when provided with environmental enrichment. Observing their behaviors during different times of the day can provide fascinating insights into their natural instincts and preferences.
  • Crested geckos are known for their gentle and docile nature, making them suitable pets for reptile enthusiasts of all experience levels. They can be easily tamed and handled, although it’s important to approach them gently and support their body to avoid causing stress or injury.
  • In addition to their physical adaptations, crested geckos possess a unique defense mechanism. When threatened or frightened, they may “play dead” by lying motionless, sometimes even with their mouth open. This behavior, known as thanatosis, aims to deceive potential predators into thinking that the gecko is already dead and not worth pursuing.
  • Crested geckos are known for their ability to regenerate lost or damaged tissues. If they happen to lose a part of their tail, for example, it can gradually regenerate over time, although the regenerated tail may not have the same appearance or function as the original.


Crested geckos are fascinating reptiles with a rich history, intriguing physical features, and captivating behaviors. Understanding their origins, physical traits, behavior, dietary requirements, and appropriate care is essential for providing them with a comfortable and healthy life in captivity. By creating a suitable habitat, offering a balanced diet, and monitoring their health, we can ensure that these enchanting creatures thrive and bring joy to our lives for many years to come.

So, if you’re ready for a reptilian companion that’s as fascinating as it is beautiful, consider adding a crested gecko to your family and embark on an adventure in the world of these remarkable reptiles. Their crests, color-changing abilities, climbing skills, and gentle personalities make them a unique and rewarding pet choice.
