In short: An adult blue tongue skink needs a ground-focused enclosure of at least 120 × 60 × 60 cm, better 150 × 75 × 60 cm or more. Provide a basking surface of 35–38 °C, a cool side of 24–28 °C, strong UVB and 10–15 cm of diggable substrate. Humidity depends on the species: 40–60 % for Australian, 60–80 % for Indonesian blue tongues. At least two large, low hides complete the setup.

How big should a blue tongue skink enclosure be?
Blue tongue skinks (Tiliqua species) grow to 45–60 cm and can live 15–20 years or longer. They are heavy-bodied ground dwellers that patrol their territory, dig and wedge themselves under objects. Floor space matters far more than height.
For one adult, 120 × 60 × 60 cm (L × W × H) is the minimum most keepers accept. A floor area of 150 × 75 cm or more is noticeably better, because it allows a real temperature gradient and room to explore. Height beyond 60 cm is useful mainly for lighting distance, not for climbing.
Australian or Indonesian: does the species change the setup?
Yes, mainly in humidity. Blue tongues sold as pets come from two very different regions.
| Factor | Australian (e.g. Northern, Eastern) | Indonesian (e.g. Tanimbar, Halmahera, Merauke) |
|---|---|---|
| Natural habitat | Dry woodland, grassland, semi-arid areas | Humid forest edges, plantations |
| Humidity | 40–60 % | 60–80 % |
| Substrate | Soil-sand mix, drier on top | Moist soil, coco fibre, cypress mulch |
| Temperament | Usually calm, mostly captive-bred | Often shyer, more often wild-caught |
| Typical price in 2026 | about 150–300 € | about 100–200 € |
Temperatures and enclosure size are the same for both groups. If you buy an Indonesian skink, add a humid hide filled with damp moss and mist the substrate lightly in the evening.
What temperatures and lighting do blue tongue skinks need?
- Basking surface: 35–38 °C, measured with an infrared thermometer on the stone.
- Warm side air: 30–32 °C.
- Cool side: 24–28 °C.
- Night: 20–24 °C; no extra heat is usually needed at normal room temperature.
- UVB: a T5 high-output tube covering about two thirds of the enclosure length, replaced every 12 months.
- Day length: 12–14 hours on a timer.
Use a halogen spot as the basking lamp, run it through a dimming thermostat and keep a min/max thermometer on both sides of the enclosure.
How should a blue tongue skink enclosure be laid out?
This layout fits a 150 × 75 × 60 cm front-opening enclosure. It scales down to 120 cm by reducing the decor in the middle.
- Warm side (left): halogen spot and UVB tube above a large, flat basking stone. A hide placed partly under the warm zone lets the skink warm up out of sight.
- Middle: open ground with a low root or flat rock slabs to explore, scattered leaf litter and a feeding area on a flat stone or slate that is easy to clean.
- Cool side (right): the second hide, a wide, shallow water bowl that cannot tip over, and, for Indonesian skinks, the humid moss hide.
- Floor: 10–15 cm of a soil, sand and coco mix that holds burrows.
- Back wall: a 3D rock or cave background. Skinks do not climb much, but the background gives depth, creates sheltered nooks at floor level and hides cables in the service chamber.

What kind of hides do blue tongue skinks need?
Blue tongues love to squeeze themselves under things, so a good hide is wide and low rather than tall. Give at least two, one warm and one cool. Each should be large enough for the whole skink, including its tail.
One important detail: place heavy hides and rocks directly on the enclosure floor before you add substrate. Skinks dig, and a hide sitting on top of loose soil can collapse onto an animal tunnelling underneath. Lightweight artificial hides such as the reptile rocky island reduce this risk further. Backgrounds with an integrated cave, like the sand cliff shelter, add a third hiding place without using floor space. For more on number, size and placement, see our guide to reptile hides and caves.

Which VivaDecor background fits which skink enclosure?
Measure the inside of your back glass and compare with the background size guide.
| Enclosure (L × W × H) | Stage | Background (W × H) | Note |
|---|---|---|---|
| 90 × 45 × 45 cm | Juvenile | 87.5 × 42.5 cm | Temporary |
| 100 × 50 × 50 cm | Juvenile | 97.5 × 47.5 cm | Temporary |
| 120 × 60 × 60 cm | Adult (minimum) | 117.5 × 57.5 cm | Full coverage |
| 150 × 60 × 60 cm | Adult | 147.5 × 57.5 cm | Full coverage |
| 150 × 80 × 80 cm | Adult, recommended | 147.5 × 57.5 cm or custom | Standard size leaves a strip at the top |
| 180 × 90 × 60 cm or larger | Spacious setup | Custom size | Made to measure on request |
What do blue tongue skinks eat?
Blue tongues are omnivores. A balanced diet is roughly half animal protein (insects, snails, cooked egg, lean meat), about 40 % vegetables and greens and around 10 % fruit. Adults eat two to three times a week, juveniles more often. Dust food with calcium and offer a multivitamin once a week.
What are common setup mistakes?
- Thin substrate. Without 10–15 cm to dig, skinks cannot burrow naturally.
- Hides on loose soil. They can collapse when the skink digs underneath.
- Wrong humidity for the species. Indonesians kept dry get shedding problems; Australians kept wet risk skin infections.
- Weak UVB. Compact bulbs or old tubes do not provide enough UV.
- A tall, narrow enclosure. Skinks need floor space, not height.
- Keeping two skinks together. Adults are territorial and often bite each other.
Why artificial decor works well for skinks
Skinks push, dig and rub against everything. Our rocks, roots and hides are hand-cast and painted, robust yet lightweight, and they never rot or grow mould in moist Indonesian setups. Unlike collected wood, nothing needs boiling or baking, and a quick rinse with warm water is enough for cleaning.
What does a blue tongue skink cost in the first year?
The skink itself is often the smallest item. These are approximate 2026 prices in EUR for an adult setup of about 150 × 75 × 60 cm.
| Item | Approximate 2026 price |
|---|---|
| Blue tongue skink (captive-bred) | 100–300 € |
| Enclosure 150 × 75 × 60 cm | 350–700 € |
| Halogen spot, T5 UVB unit, dimming thermostat | 150–250 € |
| Substrate, water bowl, thermometers | 60–120 € |
| 3D background, hides, rocks and roots | depending on size and choice |
| Food, supplements, electricity, UVB replacement (year one) | 250–400 € |
| Vet check | 50–100 € |

FAQ
Are blue tongue skinks good for beginners?
Yes, captive-bred Australian blue tongues are among the calmest pet lizards. They do need a large enclosure and strong UVB.
Do blue tongue skinks climb?
Only a little. Low roots and flat rocks are enough; avoid high ledges, as they are poor climbers and can fall.
How deep should the substrate be?
10–15 cm is ideal so tunnels hold their shape.
Do blue tongue skinks brumate?
Australian species often reduce activity in winter. Only allow brumation in a healthy, well-fed skink and ideally after a vet check.
