Northern Blue-tongued skinks are native to Australia, where they inhabit a wide range of warm and dry environments. In the wild, they can often be found sheltering among rocks, fallen logs, leaf litter, and dense vegetation, using these areas for protection from predators and extreme temperatures. Their natural habitat typically consists of sandy or compacted soils, scrubland, grasses, shrubs, and scattered trees. During the hottest parts of the day, blue-tongued skinks seek shelter beneath vegetation, logs, rocks, or in burrows, emerging to bask and forage when temperatures are more suitable.

Housing:

Due to their size, intelligence and activity levels, Skinks need a large enclosure. It is recommended to keep them in a wooden vivarium, we recommend using a 4ft x 2ft x 2ft vivarium as a bare minimum, but bigger highly recommended. Proper ventilation and sliding glass doors are essential for the enclosure. You should also ensure there is a suitable high runner to be able to offer a deep substrate.

Heating

Northern Blue-Tongued Skinks are diurnal reptiles, meaning they are active during the day. They require a suitable heat and UVB gradient throughout the enclosure to replicate their natural environment and allow them to regulate their body temperature naturally.

Enclosure Readings

• Basking Spot: 35–40°C
• Warm Side: 28–32°C
• Cool Side: 22–26°C
• Night-Time Temperature: 18–22°C
• Humidity: 40–60%, with higher levels during periods of natural humidity
• UVI: Approximately 3–4 at the basking area

It is important to provide a clear temperature gradient, allowing your skink to move freely between the warm basking area and cooler areas of the enclosure.

Night-time temperatures can safely drop, provided they remain within a suitable range. Additional night-time heating is generally not required if the room temperature remains appropriate.

The enclosure should still have good ventilation and should not remain excessively damp for prolonged periods.

All heating equipment should be connected to an appropriate thermostat to maintain safe and stable temperatures and prevent overheating.

UVB Lighting:

Blue-tongued skinks are diurnal reptiles that require strong UVB for healthy bones and calcium absorption. As a Zone 3 species, we recommend a 12% T5 UVB tube, positioned overhead to create a natural UVB gradient. Our setups include all essential heating and lighting for easy, reliable care.

Substrate

For Blue-Tongued Skinks, use a deep, soil-based substrate that allows them to dig and burrow naturally. A suitable option would be EarthMix Arid or another reptile-safe organic soil mix. The substrate should be deep enough to allow your skink to fully burrow, with around 10–15 cm being a good starting point.

A deep layer should be provided to allow your skink to dig and create burrows. The substrate should be spot-cleaned regularly and replaced when it becomes heavily soiled, compacted, or begins to smell.

Avoid substrates such as calci-sand, wood shavings, cedar, pine, and dusty or highly particulate substrates, as these can present respiratory or ingestion risks.

Cleaning

Daily: 

• Change old water for fresh water 
• Spot clean if needed

Weekly:

• Disinfect water dish with reptile safe disinfectant 
• Wipe down glass
• Agitate substrate

Monthly:

• Wipe decor with reptile safe disinfectant 
• Replace substrate

Decoration

How you decorate your enclosure ultimately comes down to personal choice, but it is important to provide plenty of cover, hides, and ground-level enrichment for your Blue-Tongued Skink. They are naturally terrestrial and enjoy exploring, burrowing, and moving through dense vegetation.

We recommend adding a variety of cork bark, sturdy branches, rocks, logs, and reptile hides to create areas for your skink to explore and shelter in. Make sure all decorations are secure and cannot collapse or injure your skink.

Providing several hides throughout the enclosure will allow your skink to choose between warmer and cooler areas while still feeling secure.

Dietary and Water Requirements:

Blue Tongue Skinks are omnivores, consuming a mix of insects, meat, veg and fruit. We recommend 50-60% protein, 40-50% veg and 0-10% fruit.

Certain items like iceberg lettuce, onions, and citrus fruits should be avoided.

 Highly nutritious food includes:

Protein:

Insects such as locusts, dubias, crickets

EvoRX

Whole Prey eg mice

Snails

Eggs

Turkey Mince

Fish

Veg:

Leafy Greens

Kale

Spinach

Carrot

Courgette

Pac choi

Butternut squash

Fruit:

Blueberries

Banana

Mango

Calcium, Vitamin, and Mineral Supplements:

Supplements such as a good quality Calcium Dust without D3 and vitamin dust should be provided, especially for young Skinks, ensuring proper growth and development. These supplements should be given routinely.

Care

✅ A healthy Blue-Tongued Skink:

• Bright, clear eyes.

• Smooth, healthy-looking skin with no wounds or retained shed.

• Alert, responsive, and active during the day.

• Good body condition with a strong appetite.

• Able to walk normally with no signs of weakness or difficulty moving.

• Strong, steady grip and normal use of all four limbs.

• Clear nostrils and normal breathing with no wheezing, clicking, or discharge.

• Firm jaw with no swelling or abnormalities.

⚠️ An unhealthy Blue-Tongued Skink:

• Sunken, cloudy, or dull eyes.

• Wrinkled or loose skin, which can be a sign of dehydration.

• Retained or stuck shed, particularly around the toes and tail.

• Soft or swollen jaw, weakness, tremors, or difficulty moving, which can be associated with metabolic bone disease (MBD).

• Lethargy or a noticeable reduction in normal activity.

• Difficulty walking, weakness, or dragging of the limbs.

• Loss of appetite or a sudden change in feeding behaviour.

• Mouth problems such as redness, swelling, discharge, or mucus, which may indicate an infection.

• Wheezing, clicking, open-mouth breathing, or nasal discharge, which can indicate respiratory problems.

🚫 Things To Avoid 🚫

• Never house Blue-Tongued Skinks together.

• Do not grab or pull your skink by the tail.

• Do not leave uneaten fresh food in the enclosure for extended periods, as it can spoil and attract flies or other pests.

• Do not feed wild-caught insects, as they may contain parasites or have been exposed to pesticides.

• Do not use coloured heat lamps, such as red or blue bulbs. These can interfere with your skink's natural day/night cycle. Use appropriate white basking and heating lamps instead.

• Do not pull retained shed off yourself, as this can damage the skin. If your skink has persistent stuck shed, seek advice from an experienced reptile keeper or exotic veterinarian.

• Avoid sudden changes in temperature, humidity, lighting, or diet, as blue-tongued skinks benefit from a stable environment.
