In terms of lifespan, the Neon Day Gecko can live up to 10 years in captivity with a proper diet and lighting, according to some sources. This relatively long lifespan, coupled with its dynamic behaviors and stunning appearance, makes it a popular choice for reptile enthusiasts.

However, potential owners should bear in mind that this longevity also means a long-term commitment to the care of these animals.

The reproductive behaviors of the Neon Day Gecko are also intriguing. These geckos reach sexual maturity at around 10-12 months of age. Once mature, they lay clutches of two eggs approximately every four weeks. Interestingly, they have a unique preference for laying their eggs in bamboo.

This is likely due to the protection that bamboo offers from predators and the relatively stable temperature and humidity conditions that it provides. This habit is a testament to the gecko’s adaptability and its ability to exploit available resources in its environment.


Creating a comfortable, safe, and stimulating environment for a Neon Day Gecko is paramount for its well-being and longevity. It’s essential to consider factors like enclosure size, lighting, and diet when setting up a habitat for this small yet dynamic creature.

The Neon Day Gecko, despite its small size, requires a spacious enclosure to thrive. This is primarily due to its arboreal nature, meaning it spends a significant amount of time climbing and exploring vertical spaces. For a single gecko, the minimum recommended enclosure size is 12 inches long, 12 inches wide, and 18 inches high.

However, always remember that larger is always better, giving the gecko more room to explore and imitate its natural environment more accurately.


Lighting is another vital component of a Neon Day Gecko’s habitat. As diurnal creatures, they rely heavily on the day-night cycle to regulate their behaviors, including feeding, mating, and sleeping. Therefore, providing a source of UV light in the enclosure can help mimic the sunlight they would naturally receive in the wild.

The UV light also plays a critical role in their health, aiding in the synthesis of vitamin D3, which is necessary for calcium absorption.

Can Neon Day Geckos Swim?

Neon Day Geckos, like most geckos, are not adapted for swimming. They are arboreal creatures, meaning they are adapted for life in the trees. They have toe pads equipped with tiny hair-like structures that allow them to climb and adhere to even smooth surfaces.

While they can move through shallow water and they may sometimes do so to drink or cool off, they do not “swim” in the way that aquatic or semi-aquatic animals do. They should not be kept in an environment with deep water as they could potentially drown.

Always ensure that any water in their enclosure is shallow enough for them to comfortably navigate. Remember, it’s always important to replicate a pet’s natural habitat as closely as possible to ensure they stay healthy and stress-free.

Neon Day Gecko Diet

The Neon Day Gecko (Phelsuma klemmeri) has a diet that mainly consists of insects and nectar in the wild. In captivity, this diet can be replicated to ensure the gecko remains healthy and receives all the necessary nutrients. Insects form a significant portion of the Neon Day Gecko’s diet. Common feeder insects include crickets, fruit flies, mealworms, and other small insects.

It is important to offer a variety of insects to provide a balanced diet. The insects should be gut-loaded, meaning they are fed nutritious food that is then passed onto the gecko. In addition to insects, the Neon Day Gecko also consumes nectar in the wild. This can be replicated in captivity by offering the gecko fresh, mashed fruit, or a commercially available nectar substitute.

Some keepers also use a mix of fruit baby food and honey to simulate nectar. All food offered to the Neon Day Gecko should be appropriately sized. The general rule is that the food item should not be larger than the space between the gecko’s eyes.

Lastly, supplementation is crucial in the diet of a captive Neon Day Gecko. Calcium and vitamin D3 supplements should be dusted onto the insects before feeding. This helps prevent metabolic bone disease, a common ailment in reptiles that do not receive enough calcium or vitamin D3 in their diet.

Neon Day Geckos as Pets

The prospect of keeping a Neon Day Gecko as a pet can be exciting, particularly due to their vibrant colors and active daytime behavior. However, potential owners must consider their care requirements and behavior towards humans before making a commitment.
