Dietary Requirements

When it comes to their diet, crested geckos have some pretty specific requirements. In order to maintain a healthy living environment, these reptiles need a balanced nutritional plan that meets their hydration needs and provides them with the vitamins and minerals they need for growth. It is important to understand what crested geckos can eat so you can ensure your pet gets enough of the right nutrients.

Crested geckos are omnivorous reptiles so they eat both plant-based food as well as small insects. They prefer food with a higher fat content such as cooked chicken or eggs, but must also be given fruits and vegetables for necessary vitamins and minerals. A good rule of thumb is to feed your gecko twice per week, providing only enough food that they will consume in 3 minutes or less each time.

Insects such as crickets, mealworms, waxworms, roaches or even silk worms can make up the bulk of their diet since they provide protein and other essential nutrients needed for growth. Insects should be gut-loaded with calcium-rich foods like kale or spinach before feeding them to your pet in order to increase the calcium content of the insects themselves. Be sure not to overfeed insect prey because too many nutrients at once can lead to health issues down the road.

It’s also important to supplement your crested gecko’s diet occasionally with minerals such as calcium powder or Vitamin D3 which are especially beneficial during breeding season and molting periods when additional nutrition is necessary for proper development. Without these supplements, deficiencies may arise over time leading to a variety of health problems from shell rot to metabolic bone disease – all avoidable if nutrition is managed correctly from the start!

Crickets are a crested gecko’s best friend – they’ll eat an endless amount! Feeding your crested gecko crickets is a great way to help them stay healthy, as these nocturnal insects provide essential proteins, fats, and calcium.

Crickets should always be offered in moderation because too many can lead to digestive problems or obesity. Be sure to monitor your geckos’ eating habits and adjust accordingly if needed.

Mealworms are a great way to give your crested gecko some variety in their diet! These small, soft-bodied insects are packed with essential nutrients and minerals.

Variety is key when offering meals for crested geckos, so by including waxworms periodically you can help ensure your pet gets all the necessary nutrients for good health. It is recommended that waxworms be used no more than two or three times a week in combination with other feeders like crickets and mealworms.

Moving on from waxworms, fruits and vegetables should be included as part of the crested gecko’s diet for optimal nutrition.

Depending on the size of your gecko, you can offer small pieces of organic produce such as apples, bananas, berries, mangos, grapes, melons or pears.

With proper care and nutrition crested geckos can live up to 15 years! Moving on to the topic of commercial diets…

Commercial Gecko Diets

Providing a balanced diet with commercial gecko food is essential for maintaining your pet’s health and vitality, as it has been specially formulated to meet their nutritional requirements. These foods are usually available in the form of pellets or powder and they are designed to provide crested geckos with all the nutrients they need. Live foods, such as crickets, mealworms and waxworms can also be offered occasionally as part of a gut-load diet. It is important that you feed your crested gecko according to the directions on the packaging of its food. For example, some products require feeding every other day while others recommend daily feeding. Additionally, you should always keep fresh water available for your pet at all times.

When choosing a commercial food for your crested gecko make sure that it contains high-quality ingredients such as calcium-rich vegetables, fruits, insects and minerals. Also look out for added vitamins which can help ensure that your pet gets all the necessary nutrients from its diet. When providing live foods make sure you give them an adequate gut load prior to serving them to your reptile companion in order to provide additional nutrition and enhance flavor. To conclude, making sure your crested gecko receives a well-rounded diet comprising both commercial foods and occasional live meals will go a long way towards ensuring its good health and wellbeing over time. Moving on then to supplements…


In addition to commercial gecko diets, crested geckos can also benefit from supplements. Supplementing a crested gecko’s diet with the right vitamins and minerals is essential for keeping them healthy. Here are three ways you can supplement your crested gecko’s diet:

  1. Phytosupplements – Phytosupplements are plant-based supplements that provide essential vitamins and minerals for your crested gecko. They come in a variety of forms, including powder, pellet, or liquid form.

  2. Calcium Supplements – Calcium supplements are important for providing additional calcium to help keep your crestie’s bones strong and healthy. These supplements can be purchased in powdered or liquid form and should be added to their food once every other week.

  3. Vitamin Supplements – Vitamin supplements provide additional vitamins that may not be present in the food they eat on a regular basis, such as vitamin A and D3. These should be used sparingly as too much of certain vitamins can cause health problems in cresties. It is best to consult with a veterinarian before giving any supplement to make sure it is safe for your pet lizard.

When supplementing your crested gecko’s diet, it is important to remember that these should only be used as an occasional treat or boost of nutrition rather than a replacement for fresh vegetables and fruits they would normally eat on their own accord. If you find yourself needing to give them more than two treats per week, it may be time to switch their diet up so they don’t become reliant on human-made foods for sustenance!
