Giant Day Gecko Care

The Giant Day Gecko is a brightly colored arboreal lizard native to Madagascar. Known for its striking green body with red or blue markings, it can grow up to 12 inches in length. These geckos are diurnal and thrive in warm, humid environments, with temperatures between 75-85°F and a humidity level of around 60-80%.

They require a vertically oriented enclosure with plenty of foliage and climbing surfaces. Giant Day Geckos are generally skittish and should not be handled frequently, as their delicate skin can be damaged easily.

Species Summary

It is active during the day, unlike many other gecko species. In captivity, it requires a vertically oriented enclosure with high humidity (60-80%) and temperatures between 75-85°F. This species is omnivorous, feeding on a diet of insects, fruit, and commercial gecko food. Handling is discouraged due to its delicate skin, which is prone to damage.

Average Giant Day Gecko Size

The average size of a Giant Day Gecko is about 8 to 12 inches (20 to 30 cm) in length, with males typically being slightly larger than females.

Lifespan

The Giant Day Gecko has a lifespan of 10 to 15 years in captivity when provided with proper care, including the right environment, diet, and husbandry.

Appearance & Colors

The Giant Day Gecko is known for its striking appearance, featuring a bright green body with varying patterns of red or orange markings along its back and head. Some individuals may also have blue or turquoise hues around the limbs and tail. The underside is typically a pale white or yellow.

Their large, expressive eyes lack eyelids, and they have adhesive toe pads that allow them to climb smooth surfaces with ease. This vibrant coloration serves both as camouflage in their natural habitat and as a display for attracting mates or deterring rivals.

Giant Day Gecko Care

Caring for a Giant Day Gecko involves creating an environment that mimics its natural tropical habitat. They require a tall, vertically oriented enclosure with plenty of climbing opportunities, like plants, branches, and vines. The enclosure should maintain a temperature range of 75-85°F during the day, with a slight drop at night, and a humidity level of 60-80%, achieved through misting.

They are omnivorous, and their diet should include a variety of insects (crickets, roaches, and occasional waxworms) and fruit purees, as well as commercial gecko diets.

Handling should be minimal due to their delicate skin, which can tear easily when grabbed. Regular cleaning of their habitat and ensuring a stress-free environment is important for their overall well-being. With the right care, Giant Day Geckos can thrive for up to 10-15 years.

Enclosure Size

A suitable enclosure for a Giant Day Gecko should be vertically oriented and at least 18x18x24 inches in size. This allows ample space for climbing, which is essential for their active, arboreal nature. Larger enclosures are even better, providing more room for enrichment and a healthier environment.

Recommended Habitat Setup

A well-designed habitat for a Giant Day Gecko should mimic its tropical environment. The enclosure should be vertically oriented, with dimensions of at least 18x18x24 inches, and include the following elements:

Substrate: Use moisture-retaining substrates like coconut fiber, sphagnum moss, or a bioactive setup with live plants to maintain humidity.
Climbing Structures: Provide plenty of branches, cork bark, vines, and bamboo for climbing.
Lighting: A 5-10% UVB bulb should be used along with a 12-hour day/night cycle.
Temperature: A nighttime drop to 70-75°F is ideal.
Humidity: Maintain a humidity level of 60-80%, achieved by misting the enclosure 1-2 times daily.
Water Source: Misting provides drinking water, as these geckos often drink droplets from leaves rather than standing water.

Temperature & Lighting

The temperature and lighting setup for a Giant Day Gecko is critical for its health and well-being:

Temperature: Maintain a daytime temperature range of 75-85°F (24-29°C), with a basking spot that reaches around 90°F (32°C). A heat source like a ceramic heat emitter or heat bulb can be used to maintain these temperatures.
Lighting: UVB lighting is essential for Giant Day Geckos, as it helps them synthesize vitamin D3 and absorb calcium, preventing metabolic bone disease. Use a 5-10% UVB bulb, and ensure it covers about two-thirds of the enclosure. The lights should be on for 10-12 hours a day to mimic their natural day/night cycle.

This setup helps ensure their thermoregulation and provides the UVB exposure they need for long-term health.

Humidity

Giant Day Geckos thrive in a humidity range of 60-80%. To maintain this, mist the enclosure 1-2 times daily, use moisture-retaining substrates like coconut fiber or sphagnum moss, and incorporate live plants to help retain moisture. Proper humidity supports their hydration, skin health, and shedding.

Water

Provide water for Giant Day Geckos by misting the enclosure regularly to create droplets they can drink from. It’s also helpful to include a shallow water dish, although they may prefer drinking from misted surfaces. Ensure the water dish is cleaned and refilled regularly to prevent contamination.

Food & Diet

Giant Day Geckos eat a mix of crickets, roaches, and occasional waxworms, which should be gut-loaded and dusted with calcium powder. They also enjoy fruit purees or baby food, like mango or papaya, and can be given commercial gecko diets for balanced nutrition. Offer these foods 2-3 times a week, adjusting based on their size and activity.

Potential Health Issues

Giant Day Geckos may experience health issues such as metabolic bone disease due to insufficient UVB lighting or calcium in their diet, leading to softened bones and deformities. They can also suffer from parasites, causing weight loss and lethargy, or skin infections from poor humidity and improper handling. Respiratory issues may arise from low humidity or sudden temperature changes. Regular monitoring and proper care are key to preventing these problems.

Behavior & Temperament

Giant Day Geckos are generally active and curious, spending much of their time climbing and exploring their habitat. While they can be skittish and may not tolerate frequent handling well, they are not aggressive. Their behavior includes territorial displays, such as head bobbing or tail waving, especially during mating or when threatened. They are best enjoyed as display animals rather than pets for handling.

Handling Them

Handling Giant Day Geckos should be minimal and gentle due to their delicate skin and stress sensitivity. If handling is necessary, approach slowly and avoid grabbing them, as this can cause injury. Instead, gently coax them onto your hand or a soft surface. Frequent handling can lead to stress and health issues, so it’s best to interact with them primarily through observation and feeding.

Closing Thoughts

Giant Day Geckos make fascinating and vibrant display animals when provided with the right care. Their needs for a well-maintained, tropical environment, along with a varied diet and minimal handling, help ensure they remain healthy and stress-free. With proper setup and attention, these geckos can thrive and offer a colorful addition to any reptile enthusiast’s collection.
