Crested geckos make fascinating pets with their unique behaviors and captivating appearance. One behavior that often catches the attention of their owners is their tendency to hang upside down. 

To truly understand this behavior, we must delve into the incredible biological adaptations of crested geckos. Their flexible limbs and toes allow them to contort their bodies and grip surfaces with astonishing precision. Picture their tiny toes, equipped with specialized adhesive pads, clinging effortlessly to the bark of a tree or the smooth walls of their enclosure. It is this remarkable grip that enables them to hang upside down without any apparent effort.

But why do they choose to hang upside down in the first place? Well, it turns out that there are a couple of reasons behind this behavior. Firstly, crested geckos are natural climbers, always seeking higher ground to establish their territories and find safe hiding spots. By hanging upside down, they can easily access elevated perches where they feel secure and have a better view of their surroundings. It’s their way of claiming their space and maintaining a strategic advantage.

In this blog, we will delve into the reasons behind this behavior and explore the factors that influence it.

Understanding Crested Gecko Behavior


Before we dive into the upside-down hanging behavior, let’s take a moment to understand the natural behavior patterns of crested geckos. These arboreal creatures are native to the tropical rainforests of New Caledonia. In their natural habitat, they spend most of their time in the trees, clinging to branches and hiding among the foliage.

Their bodies are adapted for climbing, with flexible limbs and toes that allow them to navigate their environment with ease. This adaptation also enables them to grip onto surfaces securely, whether it be the rough bark of a tree or the smooth sides of their enclosure.

Hanging Upside Down: The Behavior Explained


The ability of crested geckos to hang upside down is a result of their remarkable biological adaptations. One such adaptation is their flexibility. Their limbs and toes have a wide range of motion, allowing them to contort their bodies and hold onto surfaces in various positions. When they hang upside down, they rely on their strong grip to cling to a branch or the side of their enclosure. This behavior is not only fascinating to observe but also serves a practical purpose.

Seeking higher ground is another reason why crested geckos exhibit this behavior. In their natural habitat, they climb vertically to find elevated perches where they can rest, hide, and observe their surroundings. By hanging upside down, they can access these higher areas more easily and feel more secure. It also allows them to have a better vantage point, where they can monitor potential threats or sources of food.

Factors Influencing Upside-Down Hanging Behavior

Several factors can influence a crested gecko’s inclination to hang upside down. Thermoregulation is one such factor. Crested geckos are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. They seek out warmer areas within their enclosure to bask and absorb heat. By hanging upside down, they can position themselves closer to a heat source, such as a basking spot or heat lamp, maximizing their exposure to warmth and maintaining their preferred body temperature.

Providing appropriate hideouts and elevated spaces is essential for crested geckos. In captivity, it’s crucial to mimic their natural habitat by offering various hiding spots, branches, and platforms. These elevated spaces allow them to establish their territories, claim space, and potentially assert dominance. Hanging upside down may be a way for them to display their presence and communicate their status to other geckos.

Signs of Concern or Stress

While hanging upside down is normal behavior for crested geckos, it’s essential to be aware of signs that indicate stress or discomfort. If your gecko consistently avoids hiding spots or displays excessive hanging upside down, it may be a sign of environmental issues, such as inadequate temperature or humidity levels. 

Any sudden changes in behavior should be closely monitored, as they can indicate underlying health problems. If you notice persistent abnormalities, such as lack of appetite, weight loss, or lethargy, it’s advisable to consult a reptile veterinarian for further evaluation and guidance.

Creating an Enriching Habitat


To ensure the well-being of your crested gecko, it’s vital to provide them with a suitable and enriching enclosure. A spacious terrarium with adequate ventilation is necessary to accommodate their arboreal nature. Temperature and humidity levels should be carefully monitored and maintained within the appropriate range for crested geckos (temperature: 72-78°F, humidity: 60-80%). Proper lighting, including a UVB source, is also essential for their overall health.

When designing the enclosure, consider adding a variety of branches, vines, and foliage. This not only creates a visually appealing environment but also provides opportunities for climbing, perching, and hiding. Opt for natural materials that mimic their natural habitats, such as non-toxic branches or cork bark. These structures will give your gecko options for exploration and exercise, allowing them to engage in their instinctual behaviors.

To enhance their mental stimulation, consider incorporating elements of enrichment. This can include providing different textures for them to explore, such as artificial plants, silk leaves, or even soft moss. Offering a shallow dish of clean water for them to drink and potentially soak in is important for hydration and maintaining proper skin health.

Remember to regularly clean and maintain the enclosure to ensure a healthy living environment. 

Remove any waste promptly and clean surfaces as needed. Monitoring the humidity levels and misting the enclosure regularly will help replicate the moisture levels of their natural habitat.


Understanding why crested geckos hang upside down allows us to appreciate their fascinating adaptations and natural behaviors. By replicating their natural habitat and providing a conducive environment, we can enhance their well-being and ensure they thrive as pets. Monitoring their behavior, maintaining proper temperature and humidity, and offering an enriching enclosure will enable your crested gecko to lead a happy and fulfilling life in captivity.

Always remember to consult reputable sources and seek guidance from experienced reptile owners or veterinarians to ensure you are providing the best care for your crested gecko. With the right environment and attention to their needs, you can enjoy the beauty and marvel at the natural behaviors of your crested gecko as they gracefully hang upside down in their cozy habitat.
