Blue Tongue Skink Diet

As captivating as they are with their unique blue tongues, blue tongue skinks have captured the hearts of reptile enthusiasts across the globe. Not only do they boast an intriguing appearance, but their dietary habits also present a fascinating topic for anyone interested in reptile care.

With an omnivorous palette that requires a mix of vegetables, fruits, and proteins, understanding the nutritional needs of a blue tongue skink is crucial for their health and longevity. This guide draws on the latest insights and expert advice to offer you a comprehensive look into the dietary world of these remarkable creatures.

Understanding Blue Tongue Skink Dietary Needs

Blue tongue skinks are known for their omnivorous diet, necessitating a well-rounded intake of both animal proteins and plant-based foods. Their dietary requirements change as they grow, with baby skinks needing daily feeding and adults thriving on meals 1-2 times a week due to their slower metabolism. This metabolic trait is crucial to consider when planning their diet to avoid overfeeding​​.

The ideal meal plan for a blue tongue skink varies with age but generally involves a mix of leafy greens, vegetables, and insects. For instance, adults benefit from a diet comprising 60% leafy greens, 30% vegetables, and 10% fruits, with insects being a vital protein source​​. It’s essential to understand the specific nutritional needs and feeding schedules to ensure your skink remains healthy and satisfied.

The Right Foods: What to Include and What to Avoid

Vegetables and fruits form a significant part of the skink diet, with specific types being more beneficial than others. Safe vegetables include squash, basil, kale, and carrots, among others. Fruits should be limited to no more than 10% of the diet, with safe options including blueberries, apples, and melons. It’s crucial to avoid certain foods that can be toxic or harmful, such as avocado, onion, and citrus fruits​​​​.

Protein sources should predominantly be insects, with staples like black soldier fly larvae and silkworms recommended. Occasional treats can include pinky mice and eggs but avoid high-fat items like superworms or anything larger than pinky mice to prevent health risks. It’s also important to steer clear of toxic bugs and plants that could harm your skink​​​​.

Vegetables and Fruits: A Closer Look

Vegetables should make up a large portion of your skink’s diet due to their nutrient content, while fruits should be given sparingly as a treat. The calcium to phosphorus ratio is a crucial factor to consider for both, ensuring your skink’s body can absorb and use these nutrients effectively​​.

Certain vegetables like basil and kale are highly recommended for their beneficial nutrient profiles, whereas some fruits, although safe, should be limited due to poor nutritional ratios and potential health risks​​.

Protein: The Building Block of a Skink’s Diet

Protein is a critical component of a blue tongue skink’s diet, primarily sourced from insects. However, it’s essential to provide a balance, avoiding high-fat or potentially harmful protein sources like certain types of fish that might contain parasites or toxic metals. Appropriately sized insects, gut-loaded for extra nutrition, form the basis of a healthy protein intake for your skink​​.

Feeding Schedule by Age

Understanding the feeding schedule by age is crucial for blue tongue skink owners to ensure their pets receive the right amount of nutrition without overfeeding.

Baby skinks, from birth to 3 months, require daily feeding as they are in a rapid growth phase, needing ample nutrients to support their development. The recommended portion is about 1-2 tablespoons of a balanced diet composed of insects, vegetables, and a small fraction of fruits​​.

As they transition into sub-adulthood, from 3 to 8 months, the frequency changes to every 2 to 5 days, maintaining the same portion size but adjusting the diet to slightly less protein and more vegetables to prevent obesity while supporting growth​​.

Adult skinks, over 8 months old, need feeding only 1 to 2 times a week. This reduction reflects their slower metabolism and reduced energy needs as growth slows. Adults can store more fat and, therefore, do not require as much food​​. This schedule helps prevent obesity, a common health issue in captive skinks due to overfeeding and lack of exercise.

Meal Planning: What to Feed Your Blue Tongue Skink

A well-thought-out meal plan is essential for blue tongue skinks to receive all necessary nutrients. The plan should include a balanced mix of leafy greens, vegetables, fruits, and insects, adhering to the skink’s natural omnivorous diet.


Adult skinks should have a diet comprising 40-50% vegetables, such as squash, basil, kale, and carrots. These should be finely chopped or shredded to encourage eating. For baby skinks, vegetables should make up about 20-30% of their diet​​​​.


Fruits are to be given sparingly, making up no more than 10% of the diet. Safe fruits include apples, pears, and melons. However, high-sugar or high-acid fruits like bananas and citrus should be avoided or limited due to poor nutritional ratios and potential health issues​​.


Insects are the primary protein source, with staples such as black soldier fly larvae and crickets. These should be gut-loaded for additional nutrition. Occasional treats can include pinky mice and eggs, but fatty and larger items should be avoided to maintain health. Fish and seafood, which may contain harmful fats, salts, and parasites, should be excluded from the diet​​.

Nutritional Supplements and Hydration


Even with a varied diet, supplements play a critical role in a skink’s health. Calcium and vitamin D3 supplements are essential for bone health and preventing metabolic bone disease, a common issue in reptiles.

These supplements should be dusted on the skink’s food two to three times a week, depending on the skink’s age and specific dietary intake​​. It’s vital to ensure a proper balance, as an excess of certain vitamins can lead to toxicity.


Hydration is another critical aspect of skink care. Skinks should always have access to a shallow dish of clean, fresh water. They not only drink but may also bathe in their water dish, which helps with hydration and skin shedding. The water dish must be shallow to prevent drowning risks and cleaned daily to maintain hygiene​​.

Through careful attention to feeding schedules, meal planning, supplementation, and hydration, owners can ensure their blue tongue skinks lead healthy, vibrant lives.

It’s important to observe your skink’s health and adjust their diet as needed, consulting with a veterinarian experienced in reptile care for advice on specific needs or health concerns.

Tips for Feeding Blue Tongue Skinks

Creating an enriching feeding experience for your skink not only addresses their nutritional needs but also their behavioral and mental well-being. Here are some tips to make feeding time both efficient and enjoyable for your skink:

  • Variety is Key: Just as humans enjoy a variety of foods, so do skinks. Rotate their diet among safe vegetables, fruits, and proteins to ensure they receive a range of nutrients and to keep them interested in their meals.
  • Presentation Matters: Some skinks may be more inclined to eat their food if it’s presented in an engaging way. Mixing foods or offering them in different textures (e.g., blending fruits or lightly cooking vegetables) can make meals more appealing.
  • Monitor Eating Habits: Pay close attention to how much your skink eats at each feeding to adjust portions as necessary. If your skink consistently leaves food uneaten, consider reducing the portion size to avoid waste and overfeeding.

Handling and Interaction

While blue tongue skinks can become quite tame and may enjoy human interaction, it’s crucial to handle them correctly to build trust and avoid stress:

  • Gentle Handling: When picking up your skink, support their entire body gently, allowing them to feel secure. Avoid sudden movements that might startle them.
  • Regular, But Not Excessive, Interaction: Regularly spending time with your skink can help them become more accustomed to your presence. However, too much handling can be stressful, so it’s important to find a balance.
  • Watch for Signs of Stress: If your skink appears agitated or attempts to hide, give them space. Forcing interaction can lead to stress and potential health issues.

Health and Well-being

Regular health check-ups with a veterinarian experienced in reptile care are essential for maintaining your skink’s health. Be on the lookout for signs of illness, such as lethargy, lack of appetite, abnormal feces, or visible injuries. Early detection and treatment of health issues can prevent more serious problems down the line.

Environmental Enrichment

Beyond diet and health, providing an enriched environment is vital for your skink’s physical and mental health:

  • Adequate Space: Ensure your skink’s enclosure is large enough for them to move around freely, with areas for hiding, climbing, and basking.
  • Temperature Gradients: Proper heating and lighting are crucial for regulating your skink’s body temperature and supporting their natural behaviors.
  • Enrichment Items: Including items like logs, rocks, and plants can simulate a more natural habitat and encourage exploration and exercise.

Final Thoughts

Caring for a blue tongue skink involves a commitment to understanding and meeting their complex needs, from diet and nutrition to environmental enrichment and health care. With patience, research, and a bit of creativity, you can provide your skink with a fulfilling life, offering not just survival but a thriving existence filled with engagement and health. Remember, the key to a happy skink is not just in the care you provide but also in the love and respect you show to your scaly companion.
