Choosing the Right Enclosure

Blue-Tongued Skink

According to a study published in the Journal of Herpetological Conservation and Biology, providing reptiles with an appropriate and stimulating environment is crucial for both their physical and mental health.

The research emphasizes that neglecting to create a habitat that resembles a reptile’s natural environment can lead to stress and even behavioral disorders.

Choosing the right home for your blue-tongue skink isn’t just an aesthetic choice; it’s essential for their overall well-being.

Their enclosure is more than just a place to reside; it’s a space where they explore, rest, and express their natural behaviors. Let’s examine the key components that will make your skink’s living space both

Comfortable and Stimulating

Size and Type of the Ideal Enclosure

Adult blue-tongue skinks are substantial creatures, often reaching lengths of up to 24 inches. Therefore, they need room to move about freely. A minimum size for an adult blue-tongue skink would be a 40-gallon breeder tank.

However, if space permits, opting for larger enclosures, like a 50 or 75-gallon tank, can offer them even more comfort. When selecting a tank, prioritize length and width over height since these ground-dwelling reptiles don’t typically climb.

Tips for Replicating Their Natural Habitat

Blue-tongue skinks hail from varied environments, from tropical forests to arid plains. To replicate this:

  1. Soil Mix: Use a mixture of coconut coir, organic topsoil, and cypress mulch as the substrate, mimicking the ground they’re familiar with.
  2. Temperature Gradients: Ensure one side of the tank is warmer (basking spot) while the other is cooler, allowing the skink to regulate its body temperature.
  3. Natural Elements: Add some flat rocks for basking, and a shallow water dish for hydration. Remember to keep the water fresh and clean.

Importance of Providing Hiding Spots

Skinks, like many reptiles, often seek refuge when they feel threatened or just want a quiet space to rest.

Providing multiple hiding spots in their enclosure is crucial for their mental well-being. This can be in the form of commercial reptile hides, overturned flower pots, or even simple cardboard boxes.

Position these hides throughout the enclosure, with at least one on the warm side and one on the cooler side, so your skink can choose where it feels most comfortable.

Designing a thoughtful environment for your blue-tongue skink, rooted in scientific understanding, ensures they lead a fulfilling and happy life in your care.

Heating and Lighting

Proper heating and lighting play a pivotal role in the well-being of blue-tongue skinks. These elements not only help in regulating their body temperature but also support their metabolic processes and overall health. Let’s explore the key factors that every skink owner should be aware of:

Ideal Temperature Range and Gradient

Blue-tongue skinks are ectothermic, meaning they rely on their environment to regulate their body temperature. To ensure they have the right conditions:

  1. Basking Spot: The basking area should be between 95°F to 100°F (35°C to 37.7°C). This warm spot allows them to thermoregulate and aids in digestion.
  2. Cool Side: The cooler end of the enclosure should maintain a temperature of 75°F to 80°F (23.8°C to 26.6°C).
  3. Night Temperature: It’s natural for the temperature to drop a bit at night, but it should not go below 70°F (21.1°C).

Using a quality digital thermometer can help you monitor and ensure these temperatures are maintained.

The Importance of UVB Lighting

While blue-tongue skinks aren’t as reliant on UVB as some other reptiles, they still benefit from it. UVB lighting aids in the synthesis of vitamin D3, which is crucial for calcium metabolism and bone health.

Without adequate UVB exposure, skinks can suffer from metabolic bone disease, a debilitating condition. Even if you’re providing dietary vitamin D3, natural UVB exposure can be beneficial.

When setting up lighting for your skink:

UVB Bulbs

Invest in reputable UVB bulbs, such as those from brands like Zoo Med, Exo Terra, or Arcadia. A 10% UVB bulb is typically suitable for blue-tongue skinks.

Basking Bulbs

For the basking spot, a halogen or incandescent bulb can provide both heat and visible light. Ensure it’s placed over the designated basking area.


Use fixtures that reflect light and heat downwards into the enclosure. A dome-style fixture with a ceramic socket is a good choice. Ensure the fixture is secure and at a safe distance to prevent burns.


Consider using timers to simulate a natural day-night cycle. Generally, a 12-hour light and 12-hour dark cycle works well.

With the right heating and lighting setup, you’re not only replicating the natural conditions blue-tongue skinks are accustomed to, but you’re also paving the way for their long-term health and vitality.

Substrate and Furnishings

The substrate and furnishings in a blue-tongue skink’s enclosure serve more than just aesthetic purposes. They contribute to the reptile’s physical well-being, mental stimulation, and overall quality of life. Here’s what you need to know to make informed choices in this area:

Blue-Tongue Skink

Best Substrate Options and How Often to Change

Substrate, essentially the “flooring” of the enclosure, plays a key role in moisture retention and odor control. For blue-tongue skinks:

  1. Cypress Mulch: Retains moisture well and is good for skinks from more humid environments.
  2. Coconut Coir: This is a renewable resource and can hold moisture without getting too soggy.
  3. Aspen Shavings: Suitable for skinks from drier environments, as it doesn’t retain much moisture.
  4. Avoid: Cedar and pine shavings, as they can release harmful oils.
  5. Change Frequency: Spot clean the substrate weekly to remove waste, and change the entire substrate monthly or when it becomes too soiled.

Essential and Optional Furnishings for the Enclosure

Creating a stimulating environment is key to a skink’s happiness. Here are items to consider:

Essential Furnishings

  1. Hides: As discussed earlier, hides are essential for the skink’s comfort and security.
  2. Basking Rocks: Flat, smooth rocks where the skink can bask.
  3. Water Dish: A shallow dish large enough for the skink to drink from and possibly soak.

Optional Furnishings

  1. Climbing Branches: While they’re ground-dwellers, skinks occasionally enjoy a bit of climbing.
  2. Hammocks: Some skink owners find that their pets enjoy reptile hammocks attached to the enclosure’s side.

Safe Plants and Decorations

Plants can add beauty and also provide additional hiding spots.

  1. Live Plants: Some safe options include spider plants, pothos, and snake plants. Make sure they haven’t been treated with pesticides.
  2. Artificial Plants: These can be easier to maintain but ensure they are made of non-toxic materials and have no sharp edges.
  3. Decorations: Natural-looking decorations like driftwood or large stones can add to the enclosure’s aesthetic. Ensure they’re stable and won’t topple over.

When setting up your skink’s living environment, always keep their natural habitat in mind. A well-furnished space not only provides them with comfort but also offers them a variety of stimuli, promoting exploratory behavior and mental well-being.

Diet and Nutrition

One of the key factors that influence the health and longevity of blue-tongue skinks is their diet. Given their omnivorous nature, they require a balanced mix of both plant-based and animal-based foods. Here’s a deep dive into their dietary needs and how you can meet them:

Overview of Their Omnivorous Diet

Blue-tongue skinks have a broad palate, happily consuming both plant and animal matter. In the wild, they munch on everything from insects to fruits, flowers, and even smaller animals. In captivity, a well-rounded diet that emulates this diversity is crucial.

Typically, a dietary ratio of 50% vegetables, 40% protein, and 10% fruits is a good rule of thumb for adults. However, younger skinks may need more protein for growth.

List of Safe Fruits, Vegetables, and Proteins

Apples (seedless)Leafy greens (e.g., dandelion greens, collard greens, but avoid lettuce as it’s low in nutrition)Crickets
BlueberriesGreen beansDubia roaches
FigsZucchiniPinky mice (occasionally)
MangoBell peppersCooked lean meats (like chicken, turkey, or lean beef, but always serve in moderation and ensure no seasonings)
PapayaBroccoli (in moderation)

Supplements and Their Frequency

Given the controlled environment of captivity, supplements help fill the nutritional gaps and ensure the skink gets all its essential vitamins and minerals.

  1. Calcium Supplement: This is vital for bone health. Dust their food 2-3 times a week with a calcium powder. If your skink doesn’t get regular UVB exposure, ensure the calcium supplement includes Vitamin D3.
  2. Multivitamin: Offer a reptile-specific multivitamin once a week to cover any other potential nutrient deficiencies.

A well-balanced diet not only ensures the physical vitality of your blue-tongue skink but also plays a role in its mood and behavior. Remember, variety is the spice of life, even for our reptilian friends. Regularly rotating the foods you offer can keep your skink interested and excited about its meals.

Breeding and Reproduction

Breeding blue-tongue skinks can be a rewarding endeavor, especially for those deeply invested in the well-being and continuity of this species.

According to a study published in the Reptile Magazine, blue-tongue skinks exhibit specific breeding behaviors influenced by environmental factors, emphasizing the importance of replicating natural conditions for successful reproduction.

However, successful reproduction requires a keen understanding of their breeding habits, a conducive environment, and meticulous care for gravid females and the hatchlings. Let’s delve into the specifics:

Overview of the Breeding Process

  1. Maturity: Blue-tongue skinks usually reach sexual maturity around 2 to 3 years of age. However, it’s advisable to wait until they’re closer to 3 years for breeding to ensure optimal health and successful reproduction.
  2. Mating Season: Typically, blue-tongue skinks mate in the spring after coming out of brumation (a reptilian version of hibernation).
  3. Pairing: Introduce the male to the female’s enclosure. If receptive, the female will allow the male to mate, which can sometimes appear aggressive. Monitor closely to ensure safety.
  4. Post-mating: After a successful mating, the male can be removed and returned to his own enclosure.

Setting Up a Breeding Environment


Before the breeding season, it’s advisable to simulate brumation. This involves reducing the temperature of their enclosure for a period, typically 2-3 months during winter, and then gradually returning to normal temperatures to “wake” them up for the breeding season.

Breeding Enclosure

While you can use the female’s regular enclosure, ensure it’s spacious and stress-free. An added hide can provide the female with privacy.


Use a substrate that retains moisture, like coconut coir, as this aids in egg incubation for species that lay eggs, or provides a comfortable space for live births.

Caring for Gravid Females and Hatchlings

1. Gravid Care

Gravid (pregnant) blue-tongue skinks will have a noticeable increase in weight and a swollen abdomen. During this time, increase her food intake and ensure a calcium-rich diet. She may become less active as the birth approaches.

2. Birth

Unlike many reptiles, most blue-tongue skink species give birth to live young. A typical litter can range from 5 to 20 babies.

3. Hatchling Care

Separation: Once the babies are born, it’s wise to separate them from the mother to prevent any accidental injuries.

4. Diet

Start feeding the babies a protein-rich diet to support rapid growth. Finely chopped vegetables and fruits can be introduced after a few weeks.

5. Handling

Limit the handling of the babies for the first few weeks to reduce stress.

6. Enclosure

Baby skinks can be kept together in a spacious enclosure, but monitored closely for any signs of aggression or dominance, especially during feeding.

Breeding blue-tongue skinks requires dedication, knowledge, and a genuine commitment to their well-being.

With the right environment and care, you can witness the miracle of life and contribute to the preservation and appreciation of this fascinating reptile.
