Crested Geckos have gained immense popularity as pets due to their unique appearance and low-maintenance requirements. As reptiles, their dietary needs are crucial for their overall health and well-being. One intriguing question that often arises is whether Crested Geckos can consume Isopods, small crustaceans commonly used as feeders for reptiles. In this blog, we will delve into the potential benefits and considerations of feeding Isopods to Crested Geckos.

Understanding Crested Geckos’ Natural Diet:


Crested Geckos are omnivorous reptiles, meaning they eat a combination of both plant matter and animal protein. In the wild, they primarily feed on a variety of insects, such as crickets, roaches, and fruit flies. They also consume fruits, nectar, and pollen from flowers. To maintain their health, it is essential to provide them with a balanced diet that meets their specific nutritional requirements.

Introduction to Isopods:


Isopods are small crustaceans often referred to as “roly-polies” or “pill bugs.” They are commonly used as feeder insects for reptiles due to their nutritional value. Isopods are available in various species, such as dwarf white isopods, powder orange isopods, and dairy cow isopods. These species differ in size and appearance, but they generally share similar nutritional profiles.

Benefits of Feeding Isopods to Crested Geckos:


Isopods offer several benefits as a food source for Crested Geckos:

A. Nutritional Value:

Isopods are rich in protein, calcium, and other essential nutrients, making them a valuable addition to the geckos’ diet. Protein is vital for growth, tissue repair, and overall development. Calcium is particularly crucial for Crested Geckos as it aids in bone health and prevents metabolic bone disease, which can lead to deformities and other health issues.

B. Dietary Variety and Enrichment:

Introducing Isopods into the diet of Crested Geckos can provide them with dietary variety and mental stimulation. In the wild, Crested Geckos have access to a diverse range of food sources, including insects, fruits, and flower nectar. Offering a variety of food items, including Isopods, can help mimic their natural feeding behaviors and prevent diet boredom. Additionally, the physical activity involved in hunting and consuming Isopods can provide enrichment and mental stimulation for Crested Geckos.

Considerations and Precautions:

While feeding Isopods to Crested Geckos can have benefits, there are some considerations and precautions to keep in mind:

A. Safety and Suitability:

It is important to ensure that the Isopods intended for consumption are safe and suitable for Crested Geckos. Avoid using Isopods collected from the wild, as they may be exposed to pesticides or parasites. Instead, opt for commercially bred and raised Isopods specifically intended for reptile feeders.

B. Size and Quantity:

Isopods should be appropriately sized for Crested Geckos to prevent choking or digestive issues. Generally, choose Isopods that are smaller than the width of the gecko’s head. Additionally, Isopods should be offered in moderation as part of a balanced diet, alongside other appropriate food items.

C. Allergies and Adverse Reactions:

While rare, some geckos may have allergies or adverse reactions to Isopods. When introducing Isopods to their diet, closely monitor your gecko for any signs of allergic reactions, such as swelling, respiratory distress, or difficulty breathing. If you notice any adverse reactions, discontinue feeding Isopods and consult a veterinarian for further guidance.

Feeding Isopods to Crested Geckos: Best Practices:

To incorporate Isopods into Crested Geckos’ diets successfully, follow these best practices:

A. Gradual Introduction:

Introduce Isopods gradually to allow the geckos’ digestive system to adjust to the new food item. Start by offering a small number of Isopods and observe their response. If they show no adverse reactions, you can gradually increase the quantity over time.

B. Balanced Feeding Routine:

Isopods should be part of a balanced feeding routine that includes a variety of suitable food items. In addition to Isopods, offer a combination of insects, such as crickets and roaches, as well as fruits and commercially available gecko diets. This variety ensures that your geckos receive a wide range of nutrients necessary for their well-being.

C. Monitor Health:

Regularly monitor the health of your Crested Geckos to ensure they are thriving on their diet. Pay attention to their weight, appetite, and overall behavior. If you notice any significant changes, such as weight loss, reduced appetite, or lethargy, it may indicate a need for adjustments in your diet. Consult with a reptile veterinarian who can provide guidance specific to your geckos’ needs.

Alternative Food Options for Crested Geckos:

While Isopods can provide valuable nutrition and enrichment for Crested Geckos, it’s important to explore alternative food options as well. Here are a few alternatives to consider:

A. Insects:

Insects are a staple part of Crested Geckos’ natural diet. Crickets, mealworms, waxworms, and dubia roaches are commonly offered to geckos. These insects are readily available, provide essential protein, and can be dusted with calcium and vitamin supplements for added nutritional value.

B. Fruits:

Crested Geckos also enjoy a variety of fruits. Offer small, bite-sized pieces of fruits such as papaya, mango, figs, and banana. Fruits provide natural sugars, vitamins, and hydration.

C. Commercial Gecko Diets:

Several commercial gecko diets are specially formulated to meet the nutritional needs of Crested Geckos. These diets are typically a mix of fruit puree, protein sources, vitamins, and minerals. They offer convenience and a balanced nutritional profile.

D. Repashy Crested Gecko Diet:

Repashy is a popular brand that produces a specific diet designed for Crested Geckos. It contains a blend of fruits, vitamins, minerals, and protein sources. This powdered diet can be mixed with water to create a gel-like substance that geckos can easily consume.

It’s important to note that a combination of these food options is often recommended to ensure a diverse and balanced diet for Crested Geckos. Experimenting with different foods and observing your gecko’s preferences and nutritional needs is key to their overall well-being.


In conclusion, Crested Geckos can consume Isopods as part of their diet, and doing so can offer various benefits. Isopods provide valuable nutrition, including protein and calcium, and contribute to dietary variety and enrichment. However, it’s crucial to consider safety, size, quantity, and any potential allergies or adverse reactions when introducing Isopods to Crested Geckos.

Remember to gradually incorporate Isopods into their diet, maintaining a balanced feeding routine that includes other suitable food options like insects, fruits, and commercial gecko diets. Regularly monitor your gecko’s health and consult with a veterinarian if you have any concerns or questions regarding their diet.

By understanding and meeting their dietary needs, you can ensure that your Crested Geckos thrive and enjoy a well-rounded diet that promotes their overall health and happiness. The inclusion of Isopods, along with other suitable food options, can provide nutritional variety and enrichment for these fascinating reptiles.
