🏠 Enclosure

Plan the adult enclosure before purchase. The minimum adult setup used here is 150 x 75 x 60 cm, with about 1.125 m² of floor area. Smaller juvenile tubs can be useful for quarantine or early feeding confidence, but they should still provide a warm hide, cool hide, water, and secure cover.

🪨 Substrate and furnishings

Use 8-12 cm of safe, diggable substrate such as cypress mulch, soil/sand mix, or another reptile-safe blend that stays slightly structured without turning dusty, sour, or wet. Keep simple paper or tile during quarantine if parasite checks, wound monitoring, or feeding records are still in progress.

Give at least two broad hides, a rough surface for shedding, a humid hide, and a basking area wide enough to warm the whole body. Avoid cedar, pine, scented bedding, slick floors, and loose food surfaces that coat meals in substrate.

💡 Lighting

Use bright visible light and species-appropriate UVB. Measure lamp output when possible, because reflector, mesh, height, and lamp age change real exposure. Night lighting is unnecessary unless used briefly for observation.

Plan lighting around Ferguson Zone 2 and a 10-12 hour photoperiod, with shade and hides available so the skink can leave the UV and heat zone.

🌡️ Temperature

• Basking spot: 35-40 °C
• Daytime air: 26-32 °C
• Cool zone: 22-26 °C
• Night: 20-24 °C

💧 Humidity and water

Target humidity is 35-55%, with a temporary humid retreat around 60-70% during sheds. Keep most of the substrate dry and ventilated; a constantly wet enclosure raises respiratory and skin-risk for this Australian form.

Provide a shallow, heavy water bowl large enough for drinking and brief soaking. Change water often because blue-tongued skinks push substrate and food into bowls.

🪳 Feeding

Feed for steady body condition rather than maximum appetite. Juveniles may eat every 2-3 days; most healthy adults do better around every 5-7 days, with portions adjusted by weight, season, and activity.

Use a controlled omnivorous rotation: leafy greens and safe vegetables, snails or insects where appropriate, egg or lean animal protein in moderation, occasional fruit, and quality prepared diets as part of the rotation. Overfeeding rich protein, fruit, or dog-food-style diets makes adults obese quickly.

Use plain calcium regularly when UVB is provided, calcium with D3 only when the lighting and diet plan justify it, and a reptile multivitamin sparingly according to product directions. Food pieces should be small enough to swallow cleanly without dragging large amounts of substrate into the mouth.

🩺 Health — warning signs

Quarantine new animals, record weight, and watch for appetite loss, abnormal posture, retained shed, skin lesions, mouth injury, respiratory signs, swelling, diarrhea, and sustained hiding. Imported or recently traded animals should have fecal testing discussed with a reptile veterinarian.

Common chronic issues are obesity, dysecdysis from wrong humidity, respiratory disease from stale damp conditions, metabolic bone disease from weak UVB/calcium planning, and stress injuries from cohabitation or insecure handling. Fixing the environment early is usually easier than treating advanced disease.
