Housing and Habitat

Terrarium Size

When it comes to providing a home for your blue tongue skink, the size of the terrarium is of utmost importance. These reptiles require spacious enclosures to ensure their well-being and allow for adequate movement. As a general rule of thumb, for a single blue tongue skink, a terrarium that measures at least 4 feet long, 2 feet wide, and 2 feet tall is recommended. However, larger enclosures are even better, as they provide more room for exploration and exercise.

Temperature and Humidity

Maintaining the optimal temperature and humidity level is crucial for the overall health of your blue tongue skink. These reptiles are ectothermic, which means they rely on external sources to regulate their body temperature. The terrarium should have a temperature gradient, with one side being warmer (around 90-95°F) and the other side being cooler (around 75-80°F). This allows the skink to thermoregulate by moving to the area that best suits its needs.

Regarding humidity, blue tongue skinks require moderate levels to mimic their natural environment. Aim for a humidity level of around 40-50%. Using a hygrometer will help you monitor the humidity accurately. Additionally, providing a shallow water dish within the enclosure will give your skink the opportunity to bathe and increase humidity if desired.


Choosing the right substrate for your blue tongue skink’s enclosure is essential for several reasons. Firstly, it provides a comfortable surface for them to burrow and explore. Secondly, it helps maintain appropriate humidity levels. Some suitable substrate options for blue tongue skinks include cypress mulch, coconut fiber, and organic topsoil. Avoid using substrates that are abrasive or dusty, such as cedar chips or sand, as these can be harmful if ingested.


Creating a stimulating and enriching environment is essential for the well-being of your blue tongue skink. Provide a variety of hiding spots, such as rocks, logs, and artificial caves, to mimic their natural habitat. This will give your skink a sense of security and encourage natural behaviors like exploring and hide-and-seek. Additionally, incorporating branches and plants can help create a more naturalistic environment, providing opportunities for climbing and perching.

Feeding and Diet

Dietary Requirements

Blue tongue skinks have diverse dietary requirements to ensure proper nutrition. They are omnivorous, meaning they consume both plant matter and animal protein. Their diet should consist of a variety of vegetables, fruits, and protein sources like insects, snails, and commercially prepared reptile foods. Leafy greens, squash, fruits like blueberries and raspberries, and lean meats like chicken or turkey are all good options to include in their diet.

It’s important to remember that blue tongue skinks have slower metabolisms compared to some other reptiles, so it’s crucial not to overfeed them. Obesity can be a serious health concern for these reptiles. Providing appropriately sized and portioned meals is key to maintaining their overall health.

Food Options

There are several food options available for blue tongue skinks, and it’s beneficial to offer them a varied diet. Insects such as crickets, mealworms, and superworms are excellent sources of animal protein and should be included regularly. You can also offer small amounts of cooked lean meat like chicken or turkey, as well as snails and slugs as occasional treats. Vegetables like collard greens, dandelion greens, and butternut squash are great choices for their plant-based nutritional needs.

Feeding Schedule

Establishing a consistent feeding schedule is essential to ensure proper nutrition and maintain your blue tongue skink’s health. Younger skinks will require more frequent meals, while adults can be fed every 2-3 days. Offer a variety of food items during each feeding session to provide a balanced diet. Remember to remove any uneaten food after a reasonable period to prevent spoilage and maintain a clean enclosure.


Blue tongue skinks require additional supplementation to meet their nutritional needs fully. Calcium and vitamin D3 are two vital supplements that should be regularly provided. Dusting insects and plant matter with a reptile-specific calcium powder before feeding ensures your skink receives adequate amounts of calcium. Vitamin D3 helps with calcium absorption, so either provide a UVB light source or use a reptile-specific vitamin D3 supplement if your skink does not receive adequate natural sunlight exposure.

Taming and Bonding

Building a bond of trust and familiarity with your blue tongue skink is essential for successful handling and socialization. It’s crucial to give your skink time to acclimate to its new environment before attempting to handle them. Start by simply placing your hand in the enclosure to allow the skink to become comfortable with your presence. Gradually progress to gently touching and handling them, always taking care to support their body correctly.

Proper Handling Techniques

When handling your blue tongue skink, it’s important to employ proper techniques to minimize stress and ensure their safety. Approach them calmly and confidently, using both hands to support their body. Never grab or squeeze them, as this can cause harm. Instead, gently scoop them up from underneath, supporting their belly and hind legs. Avoid sudden movements or loud noises, which can startle your skink.

Health and Wellness

Common Health Issues

While blue tongue skinks are generally hardy reptiles, they are susceptible to a few health issues. Some common health problems include respiratory infections, parasitic infestations, and shedding difficulties. Respiratory infections can result from inadequate temperature and humidity or exposure to drafts. Parasites can be contracted from unclean substrate or live prey. Shedding issues can occur if the humidity levels are too low or if the skink is not properly hydrated.

Signs of Illness

Monitoring your blue tongue skink for any signs of illness is crucial for maintaining their overall health. Keep an eye out for symptoms such as loss of appetite, lethargy, weight loss, abnormal stool, respiratory distress, or any unusual behavior. If you notice any of these signs, it’s important to seek veterinary care promptly to ensure timely treatment and prevent further complications.

Veterinary Care

Regular veterinary check-ups are essential for the well-being of your blue tongue skink. A reptile-experienced veterinarian can perform thorough examinations, address any health concerns, and provide advice on diet, habitat, and overall care. It’s recommended to schedule annual check-ups and establish a good relationship with a reptile veterinarian to ensure the continued health and longevity of your blue tongue skink.

Preventative Measures

There are various preventative measures you can take to minimize the risk of health issues in your blue tongue skink. Maintaining proper temperature and humidity levels, providing a clean and hygienic enclosure, and offering a balanced diet are crucial aspects of preventative care. Additionally, practicing good hygiene by washing your hands before and after handling your skink can help prevent the transmission of any potential pathogens.
