What vegetables can crested geckos eat? Crested geckos are fascinating and popular pets known for their unique appearance and low maintenance requirements. Originating from New Caledonia, these arboreal reptiles have captured the hearts of reptile enthusiasts worldwide. To ensure the well-being and longevity of crested geckos, it is crucial to provide them with a balanced diet that meets their specific nutritional needs.


A balanced diet plays a pivotal role in the overall health and vitality of crested geckos. As omnivores, these geckos require a combination of protein-rich foods and a variety of fruits and vegetables. While insects form a significant part of their diet, incorporating vegetables into their feeding routine is essential for providing essential vitamins, minerals, and fiber.


The Nutritional Needs of Crested Geckos


Crested geckos, like any other living creatures, have specific nutritional requirements for optimal health. These requirements include a balance of proteins, carbohydrates, vitamins, minerals, and fiber. Providing a well-rounded diet is essential to support their growth, immune system, and overall well-being.


Vegetables play a vital role in the diet of crested geckos. While insects are a valuable source of protein, vegetables provide essential nutrients that are crucial for their overall health. Vegetables offer a rich supply of vitamins such as vitamin A, vitamin C, and vitamin K, as well as minerals like calcium and potassium. These nutrients contribute to proper bone development, healthy skin, strong immune function, and overall vitality.


When it comes to feeding vegetables to crested geckos, variety is key. Offering a diverse range of vegetables ensures that your gecko receives a wide array of nutrients. Each vegetable brings its unique nutritional profile, contributing to a well-balanced diet. Incorporating different vegetables also helps prevent dietary deficiencies and boredom associated with a monotonous diet.


By providing a variety of vegetables, you can mimic the crested gecko’s natural diet in the wild, where they consume a wide range of plant matter.

4. Carrots


Carrots are a great source of vitamin A and fiber, promoting healthy eyesight and digestion in crested geckos. However, they should be offered in moderation due to their high sugar content. Cut carrots into thin, small slices or grate them to make it easier for your gecko to eat.


Carrots should be given sparingly as an occasional treat rather than a staple food. Excessive carrot consumption can lead to weight gain and potential digestive issues. Always monitor your gecko’s weight and overall health when offering carrots.


Other Suitable Vegetables


Cucumbers, green beans, snap peas, and broccoli: These vegetables provide additional variety and nutrition to your crested gecko’s diet. Cucumbers are hydrating and low in calories, while green beans and snap peas offer fiber and essential nutrients. Broccoli is a good source of vitamin C and calcium. Offer these vegetables in small, appropriate portions to ensure proper digestion and prevent overfeeding.


Vegetables to Avoid


While there are many safe and beneficial vegetables for crested geckos, it’s equally important to be aware of the vegetables that should be avoided. Certain vegetables can be harmful or pose risks to their health and well-being.


These vegetables are as below:

  • Potatoes: Potatoes, especially raw or uncooked ones, are not suitable for crested geckos. They contain high levels of starch and can be difficult for geckos to digest. Raw potatoes also contain solanine, a toxic compound that can cause digestive upset and other health issues.


Onions and garlic should be completely avoided in their diet due to their potential toxicity. Tomatoes and potatoes should also be omitted from their vegetable options due to digestion difficulties and potential adverse effects on their health.


Preparing Vegetables for Crested Geckos


Before offering vegetables to your crested gecko, it is essential to wash them thoroughly to remove any pesticides or chemicals that may be present. Pesticides can be harmful to your gecko’s health. Rinse the vegetables under running water, gently rubbing them with your hands to ensure proper cleaning. Alternatively, you can soak the vegetables in a mixture of water and vinegar for a few minutes, followed by rinsing.


Crested geckos have relatively small mouths, so it’s important to prepare vegetables in sizes that are easily manageable for them. Chop the vegetables into small, bite-sized pieces or thin slices. Smaller pieces not only make it easier for your gecko to consume but also minimize the risk of choking or digestive issues. Aim for pieces that are approximately the width of your gecko’s mouth.


 Different Methods of Presenting Vegetables to Your Gecko


Offer vegetables as a dish

Place the prepared vegetables in a shallow dish or feeding bowl inside your gecko’s enclosure. This allows them to explore and consume the vegetables at their own pace. Ensure that the dish is securely placed to prevent tipping or contamination.



Some crested geckos enjoy being hand-fed. Gently hold a small piece of vegetable between your fingers or with tweezers and offer it to your gecko. This method allows for interactive feeding and can help create a positive bond with your gecko. Be patient and give them time to approach and accept the offered vegetable.


Blend or puree vegetables

For geckos that have difficulty consuming solid vegetables or prefer softer textures, you can blend or puree the vegetables. Use a food processor or blender to create a smooth or slightly chunky consistency. You can mix the puree with other appropriate foods like fruit puree or baby food to add variety and enhance palatability.


Remember to remove any uneaten vegetables after a feeding session to prevent spoilage and maintain hygiene. Observe your gecko’s feeding response and adjust the presentation methods based on their preferences.


Feeding Guidelines and Tips


When it comes to feeding vegetables to your crested gecko, it’s important to establish a feeding routine and adhere to appropriate portion sizes. Offer vegetables to your gecko two to three times a week as part of their overall diet.


The portion size can vary depending on the size and age of your gecko. As a general guideline, provide a portion of vegetables that is approximately the size of their head or about 10-15% of their total diet.


Each crested gecko may have individual preferences when it comes to vegetables. Some geckos may readily accept a wide variety of vegetables, while others may be more selective. Observe your gecko’s feeding behavior and note their preferences.


If they consistently avoid certain vegetables, try offering alternative options or adjusting the presentation method to encourage their interest. Offering a diverse selection of vegetables can help cater to their individual preferences and ensure a well-rounded diet.


Regularly monitor your crested gecko’s overall health and well-being. Pay attention to their weight, digestion, and behavior. If you notice any significant changes in appetite, weight loss, or signs of digestive issues such as constipation or diarrhea, it’s essential to seek veterinary advice.

A reptile veterinarian experienced with crested geckos can provide guidance, assess your gecko’s health, and make recommendations specific to their needs.
