The crested gecko (Correlophus ciliatus) is an astonishingly beautiful reptile that originates from the tropical forests of New Caledonia. Valued for their docile nature, unique appearance and simple care routine, crested geckos have surged in popularity as pets in recent years.
One of the most fascinating aspects of crested geckos is their remarkable ability to change color. These color shifts serve important functions in the wild, such as camouflage, signaling mood, regulating body temperature and communicating with other geckos.
In this article, we explore the science behind crested geckos’ color-changing capabilities. We discuss the various factors that influence their coloration, proper care for a color-shifting gecko, and how to monitor and maintain their vivid hues in captivity. Whether you’re a seasoned crested gecko owner or researching your first pet reptile, read on to gain appreciation for these geckos’ prismatic beauty!
Overview of Crested Geckos
Let’s first review some key facts about the stunning crested gecko:
– Native to the tropical forests of New Caledonia
– Nocturnal; sleep during the day
– Grow 6-10 inches long when mature
– Live 10-20 years with proper care
– Have a row of spiky skin protrusions from head down neck and back
– Feed on insects and fruit
– Docile temperament makes them ideal pet reptile

Crested geckos’ color-changing capability relies on specialized cells in their skin containing pigments. Now let’s explore this phenomenon further.
Crested Gecko Color Change Factors
| Factor | Effects on Coloration |
|---|---|
| Mood | Stress, fear, aggression, or contentment alters skin color. |
| Health | Sickness or dehydration causes a dull or drab appearance. |
| Temperature | Colder conditions lead to darker coloration to absorb heat. |
| Light | Bright conditions cause paling, while darkness elicits darker shades. |
| Breeding Status | Sexually receptive females exhibit more defined markings. |
| Age | Younger geckos generally have bolder patterns and colors. |
The Color-Changing Abilities of Crested Geckos
Crested geckos possess specialized color-changing cells in their skin called chromatophores. Chromatophores contain pigments and can rapidly expand or contract to alter skin coloration. The two main types are:
Melanophores: Contain dark melanin pigment that expands to make skin darker.
Erythrophores: Contain reddish pigment that expands to make skin redder.
By controlling these chromatophores, crested geckos can swiftly change color to blend into their surroundings, regulate body temperature and communicate their mood or intent. Wild crested geckos utilize their color-changing abilities for:
Camouflage: Crested geckos can alter their skin to match bark, foliage and environments to evade predators.
Thermoregulation: Darkening can absorb heat, while lightening releases excess heat.
Social Signaling: Communicates dominance, submission, readiness to mate and intentions.
While their color range may be more limited in captivity, pet crested geckos retain this amazing ability to morph between various colors.
Factors Influencing Crested Gecko Coloration
A crested gecko’s specific coloration at any given time depends on several influencing factors:
Mood: Stress, fear, aggression or contentment alters skin color.
Health: Sickness or dehydration causes a dull or drab appearance.
Temperature: Colder conditions lead to darker coloration to absorb heat.
Light: Bright conditions cause paling, while darkness elicits darker shades.
Breeding Status: Sexually receptive females exhibit more defined markings.
Age: Younger geckos generally have bolder patterns and colors.
As you observe your crested gecko, you will begin recognizing these patterns and what certain color changes signify. Always optimize their habitat to bring out their most vivid, healthy colors.
Caring for a Color-Changing Crested Gecko
To keep your color-shifting crested gecko displaying deep, lustrous hues, certain care considerations are important:
– Maintain proper temperature of 70°F to 80°F during the day and 65°F to 75°F at night.
– Ensure habitat humidity stays consistent between 60% to 80%. Avoid arid conditions.
– Provide ample climbing branches, foliage and hides to make gecko feel secure.
– Use full-spectrum UVB lighting on a 12 to 14 hour cycle to allow natural daylight.
– Offer a varied diet with properly gutloaded insects and occasional fruit treats.
– Routinely clean the habitat to prevent infections that can dull coloration.
– Gently handle pet gecko frequently so it becomes comfortable with your presence.
With attentive care and nutrition, your crested gecko will show its most beautiful palette of coloration as it grows and matures in your home.
Housing Considerations for Color-Changing Geckos
Optimizing your crested gecko’s habitat helps bring out their best coloration. Consider these housing tips:
– Use natural tank furnishings the gecko can climb on and blend in with.
– Provide areas of shade and concealment for darker coloration.
– Allow direct access to heat lamps/UVB lighting for lightening.
– Incorporate foliage, bark and vines to mimic natural habitat.
– Line bottom of tank with paper towel or moss to help display colors.
– Maintain optimal temperature on both warm and cool ends of tank.
– Ensure ample ventilation and airflow to prevent humidity spikes.
An ideal habitat allows crested geckos to find their preferred temperature and lighting levels to assume their most stunning and vibrant coloration.
Dietary Recommendations for Thriving Coloration
Proper nutrition is essential for your crested gecko to display deep, lustrous colors. Follow these dietary guidelines:
– Gutload feeder insects with nutritious fruits, vegetables and grains before feeding.
– Dust insects with calcium and vitamin D3 supplements at every feeding for juveniles and 2-3 times weekly for adults.
– Offer a variety of feeder insects like crickets, roaches, silkworms and phoenix worms to provide balanced nutrition.
– Include occasional high vitamin fruits like prickly pear, figs and papaya as treats.
– Ensure fresh, uncontaminated drinking water is always available.
– Do not overfeed, as excess protein can cause dullness. Follow recommended portion sizes.
With a balanced, nutrient-rich diet, your crested gecko will exhibit consistently vibrant coloration and optimal skin health.
Common Health Issues Affecting Crested Gecko Coloration
While periodic color shifts are normal, drastic or prolonged changes can sometimes indicate an underlying health issue needing attention:
Metabolic Bone Disease – Causes faded colors and body contortions and twitches.
Respiratory Infections – Lead to diminished color vibrancy, especially in body and limbs.
Dehydration – Makes eyes appear sunken and skin coloration washed out.
Shedding Difficulties – Retained old skin can make colors appear muddled or obscured.
Diarrhea – Causes general dullness and may indicate parasitic infection.
If you notice any severe or unnatural color changes, schedule a veterinary visit to diagnose and treat any condition present. Follow your vet’s recommendations to help your gecko regain its health and coloration.
Tips for Maintaining Optimal Coloration in Crested Geckos
By being attentive to your crested gecko’s coloration and making careful observations, you can maintain their most vivid and lustrous colors:
– Look for signs linking color shifts to mood, temperature or communication.
– Note any drastic or unnatural color changes that may indicate health issues.
– Take baseline photos when gecko is young and healthy to compare future color changes against.
– Ensure lighting, temperature and humidity meet gecko’s needs and are stable.
– Weigh gecko weekly and monitor appetite to assess general health.
– Clean habitat frequently and disinfect any decor added from other tanks.
