Understanding the Diet of Crested Geckos

The diet of crested geckos plays a vital role in their overall health and well-being. As responsible owners, it’s essential to understand what constitutes a nutritious and balanced diet for these remarkable reptiles. In this section, we will explore the various components of a crested gecko’s diet, including live insects, fruits, and vegetables. By understanding their dietary requirements, you can provide your gecko with the proper nourishment they need to thrive.

Live Insects such as Crickets and Roaches

Crested geckos are insectivores, and live insects form a crucial part of their diet. Feeding them appropriately sized crickets and roaches provides essential protein and helps mimic their natural feeding behavior.

Other Options like Spiders, Grasshoppers, and Worms

In addition to crickets and roaches, you can also offer other small invertebrates like spiders, grasshoppers, and worms as occasional treats. These prey items can provide enrichment and variety in their diet.

Feeding Guidelines for Crested Geckos

Establishing proper feeding guidelines is crucial to ensure the optimal nutrition and health of your crested gecko. In this section, we will delve into the recommended feeding schedule for both hatchlings and adult geckos. 

We will discuss portion sizes, the importance of dietary diversity, and the significance of gut-loading insects. By following these feeding guidelines, you can ensure that your crested gecko receives a well-rounded diet that meets its nutritional needs.

Feeding Schedule for Hatchlings and Adults

Hatchlings require more frequent feedings, typically every day, to support their rapid growth. As they mature, you can transition to feeding adult crested geckos every other day or every three days. Adjust the feeding schedule based on your gecko’s appetite and body condition.

Portion Sizes

Offer appropriately sized food items that can be consumed within a short period. The size of the prey should match the width between the gecko’s eyes. Adjust the portion size as your gecko grows to prevent overfeeding or underfeeding.

Importance of Diversity in Their Diet

Provide a diverse range of food options to meet the nutritional needs of your crested gecko. Offering a variety of insects, fruits, and vegetables ensures a balanced diet and helps prevent nutritional deficiencies.

Gut Loading Insects Before Feeding

If you choose to feed live insects, it is essential to gut-load them before offering them to your crested gecko. Gut loading involves feeding nutritious foods to the insects, enriching their nutritional value, and passing those nutrients onto your gecko.

Choosing the Right Food for Crested Geckos

Selecting the right food for your gecko is essential to provide them with a balanced and nutritious diet. In this section, we will explore the different options available, including commercial powdered food, live insects, and supplements. 

We will discuss the benefits of using commercial powdered food as a complete diet, the importance of supplementing with live insects, and the role of multivitamin supplements. By choosing the right food options, you can provide your gecko with the essential nutrients they require to thrive.

Commercial Powdered Food as a Complete Diet

Commercial powdered food formulated specifically for crested geckos can serve as a complete diet. These products often contain a balance of essential nutrients, vitamins, and minerals, providing convenience and ensuring your gecko receives a well-rounded diet.

Supplementing with Live Insects

While commercial powdered food can be the primary source of nutrition, supplementing with live insects adds variety and enrichment to your crested gecko’s diet. This combination offers a closer resemblance to their natural feeding behavior.

Multivitamin Supplements for Added Nutrition

To ensure your gecko receives all the necessary vitamins and minerals, consider supplementing your diet with multivitamin powder. These supplements help bridge any potential nutritional gaps and promote optimal health.

Mistakes to Avoid When Feeding Crested Geckos

Feeding mistakes can have detrimental effects on the health of your crested gecko. In this section, we will highlight common mistakes to avoid when feeding your gecko. We will discuss the importance of portion control, feeding appropriate foods, maintaining dietary variety, and supplementing with calcium and Vitamin D3. By being aware of these mistakes, you can ensure that your crested gecko receives a proper and well-balanced diet that supports its overall well-being.


One common mistake is overfeeding crested geckos. Overfeeding can lead to obesity and related health issues. Follow a feeding schedule and portion sizes appropriate for your gecko’s age and size. Monitor their body condition and adjust the feeding routine accordingly.

Feeding Inappropriate Foods

Avoid feeding your crested gecko foods that are toxic or harmful to them. Research and identify which foods are safe and appropriate for their consumption. Some examples of foods to avoid include citrus fruits, avocados, and foods treated with pesticides.

Lack of Variety

Offering a varied diet is crucial for crested geckos’ nutritional needs and overall well-being. A lack of variety can result in nutrient deficiencies. Include a mix of insects, fruits, and vegetables to provide a balanced diet and prevent monotony.

Not Supplementing with Calcium and Vitamin D3

Crested geckos require adequate calcium and Vitamin D3 for proper bone development and overall health. Calcium supplementation is especially important for breeding females and growing juveniles. Dust insects with calcium powder and provide a source of Vitamin D3 through appropriate UVB lighting.


Understanding the dietary needs of your gecko is essential for their long-term health and well-being. A balanced diet consisting of live insects, fruits, and vegetables, along with commercial powdered food and appropriate supplementation, is crucial. 

Remember to feed in appropriate portion sizes, provide a diverse range of food options, and avoid common feeding mistakes such as overfeeding and feeding inappropriate foods. By following these guidelines and establishing a proper feeding routine, you can ensure that your gecko receives the nutrition they need to thrive in captivity.
