How Long Can Crested Geckos Go Without Food


Welcome to the enchanting world of crested geckos, where unique characteristics and captivating behaviors make them fascinating pets to keep. Proper feeding and understanding the frequency of their meals play a crucial role in their overall well-being.

Crested Geckos’ Natural Diet in the Wild

Exploring Their Native Habitat

Crested geckos, also known as New Caledonian geckos, are native to the forests of New Caledonia, a group of islands in the South Pacific. In the wild, these geckos thrive in a tropical environment with abundant plant life and insects. Their natural diet consists of a variety of insects, such as crickets and roaches, as well as fruits, nectar, and even small vertebrates. Their unique environment influences their feeding habits, which we need to consider when caring for them in captivity.

Understanding Their Food Choices

In their native habitat, crested geckos are opportunistic feeders, meaning they eat a diverse range of food based on availability. They are known to consume insects, such as moths, flies, and caterpillars, as well as the sweet nectar from flowers and ripe fruits. This varied diet provides them with essential nutrients and energy to support their growth and survival.

The Feeding Behavior of Crested Geckos

Nocturnal Hunters

Crested geckos are primarily nocturnal, which means they are most active during the night. Their nocturnal nature influences their feeding behavior, as they become more active and alert when the sun sets. In captivity, observing their hunting and eating patterns can be an exciting experience.

Prey Size and Consumption Rate

The appropriate prey size for crested geckos depends on their age and size. Hatchlings and juvenile geckos should be offered smaller insects, while adult geckos can handle larger prey. Additionally, young geckos require more frequent feeding compared to adults, as they are growing rapidly and need a constant supply of nutrients.

Frequency of Feeding

Feeding Schedule for Juvenile Geckos

For hatchlings and juvenile geckos, daily feedings are recommended to support their rapid growth and development. Providing them with a consistent supply of appropriately sized insects and offering a variety of food items can promote their well-being during their early stages.

Feeding Schedule for Adult Geckos

As crested geckos mature into adults, their feeding schedule can be adjusted. Most adult geckos can be fed every two to three days, ensuring they receive adequate nutrition without overfeeding. However, individual geckos may have varying appetites, and it’s essential to monitor their weight and overall health to determine the appropriate feeding frequency.

Healthy and Active Geckos

Signs of a Well-Fed Gecko

A well-fed crested gecko exhibits certain signs of good health. They will have bright, alert eyes, a plump and rounded body, and a healthy-looking tail. Additionally, their skin should be smooth and free from any signs of dehydration or wrinkling.

Proper Hydration

Maintaining proper hydration is crucial for the health of crested geckos. These tropical reptiles require a humid environment, and providing access to fresh water is essential. Proper humidity levels in their enclosure ensure their skin stays hydrated and aids in shedding, which is a normal process for these geckos.

The Effects of Temporary Food Deprivation

Adaptation to Short-Term Food Scarcity

Crested geckos have evolved to adapt to short periods without food. In the wild, they may encounter times when food availability is limited. As a result, they can regulate their metabolism to conserve energy during these periods of temporary food scarcity.

Potential Risks

While crested geckos can cope with short-term food deprivation, prolonged periods without food can have adverse effects on their health. Extended fasting can lead to weight loss, nutrient deficiencies, and a weakened immune system. It’s essential to maintain a consistent and balanced diet to avoid these risks.

When to Be Concerned

Recognizing Signs of Hunger

It’s crucial to be attentive to signs of hunger or malnutrition in crested geckos. Behavioral indicators of hunger may include increased activity, searching for food, or persistent attempts to catch prey. Physically, a visibly emaciated appearance and prominent bones may suggest a lack of proper nutrition.

Monitoring Weight and Body Condition

Regularly monitoring your gecko’s weight and body condition is essential to assess their health. Maintaining a healthy body condition score ensures they are receiving enough food and nutrition to support their well-being.

The Duration of Extended Fasting

Understanding Extended Fasting

Extended fasting in crested geckos can be caused by various factors, such as stress, illness, or environmental changes. While some geckos may tolerate extended fasting better than others, it’s essential to understand the potential risks and consequences of prolonged food deprivation.

Veterinary Consultation

If you notice your crested gecko is experiencing prolonged fasting or a significant decrease in appetite, seeking veterinary advice is crucial. A reptile veterinarian can evaluate your gecko’s health and provide guidance on how to address their dietary needs effectively.

Encouraging Eating in Reluctant Geckos

Addressing Feeding Refusals

There are several reasons why a crested gecko may refuse to eat. Stress, illness, or changes in their environment can contribute to feeding refusals. Identifying the cause and addressing it promptly can help encourage them to resume normal feeding behaviors.

Offering Varied Food Choices

Crested geckos appreciate a diverse diet, and offering a variety of food items can stimulate their appetite. Trying different insect types and flavors of commercial gecko diets can entice them to eat and ensure they receive a balanced nutrition.

Nutritionally Balanced Diet

Creating a Nutrient-Rich Diet

A nutritionally balanced diet is essential for the health and well-being of crested geckos. Their diet should consist of a balance of proteins, vitamins, and minerals. Gut-loading prey insects with nutritious foods, such as leafy greens and fruits, can enhance the nutritional value of their diet.

Commercial Diets vs. Homemade Diets

Commercial gecko diets offer convenience and are formulated to meet their nutritional requirements. However, some gecko owners prefer to create homemade diets to have more control over the ingredients. Whichever option you choose, ensuring a complete and balanced nutrition plan is vital.

The Joy of Caring for Crested Geckos

A Rewarding Experience

Caring for crested geckos can be an incredibly rewarding experience. These captivating reptiles can form strong bonds with their owners, and observing their unique behaviors can be a source of joy and fascination.

Forming a Strong Bond

Proper care, attentive feeding, and a comfortable living environment contribute to the well-being of your crested gecko. As you provide for their needs, you’ll likely form a strong bond with these remarkable creatures.


In conclusion, understanding the natural diet and feeding behavior of crested geckos is crucial for their overall health and happiness. By providing a well-balanced diet, monitoring their weight and condition, and seeking professional advice when needed, you can ensure that your crested gecko thrives in captivity. Caring for these unique pets is an enriching experience, and with the right approach, you can build a lasting and rewarding relationship with your crested gecko.
