Vet Guide 2025: Blue‑Tongued Skink Care & Wellness by Dr Duncan Houston 🩺🦎

Hello! I’m Dr Duncan Houston, BVSc and founder of Ask A Vet. Blue‑tongued skinks (Tiliqua spp.) are fascinating, long-lived reptiles with distinctive cobalt‑blue tongues. In this 2025 guide, I’ll walk you through their natural history, husbandry, health needs, subspecies differences, and what it takes to keep them thriving under veterinary care. Let’s get started! 🌿

1. Natural History & Subspecies Overview

Blue‑tongued skinks belong to the genus Tiliqua, among the largest members of the skink family Scincidae :contentReference[oaicite:3]{index=3}. Native to Australia and Indonesia, these ground‑dwelling omnivores grow 18–24″ (45–60 cm) and often live 15–30+ years in captivity :contentReference[oaicite:4]{index=4}.

Common Subspecies:

• Eastern (T. s. scincoides): Widespread in southern/eastern Australia; diurnal, ground‑foraging, up to 24″ :contentReference[oaicite:5]{index=5}.
• Northern (T. s. intermedia): Larger, orange‑toned, lives ~20 years, live‑bearing 5–25 young :contentReference[oaicite:6]{index=6}.
• Shingleback (T. rugosa): Armoured body, stumpy tail, lives 10–15+ years, monogamous :contentReference[oaicite:7]{index=7}.
• Indonesian/Blue‑Tongued Giant (T. gigas): Massive (26–30″), from New Guinea & Indonesia :contentReference[oaicite:8]{index=8}.

2. Temperament & Behavior

• Generally docile, often compared to “dogs of reptiles” :contentReference[oaicite:9]{index=9}.
• Use bright blue tongue, hissing, and inflating to ward off threats :contentReference[oaicite:10]{index=10}.
• Shy at first; regular calm handling builds trust.
• Males can be territorial—avoid co-housing unless ample space is provided.

3. Enclosure Setup

3.1 Space & Structure

• Minimum 55–120 gal for adults; front-opening tanks are easier to access :contentReference[oaicite:11]{index=11}.
• Provide deep layers (≥6") of substrate for burrowing :contentReference[oaicite:12]{index=12}.
• Add hides, logs, cork rounds, and climbing decor for enrichment :contentReference[oaicite:13]{index=13}.

3.2 Lighting, Heating, Humidity

• 12 hrs UVA/UVB daily; bulbs replaced every 6 months :contentReference[oaicite:14]{index=14}.
• Create thermal gradient: basking ~90 °F; ambient ~75–85 °F :contentReference[oaicite:15]{index=15}.
• Humidity: Australian subspecies ~40–60%, Indonesian types ~60–80%; include humid hides :contentReference[oaicite:16]{index=16}.
• Always avoid heat mats; use ceramic emitters or overhead bulbs :contentReference[oaicite:17]{index=17}.

3.3 Cleanliness & Maintenance

• Spot-clean daily; full clean monthly :contentReference[oaicite:18]{index=18}.
• Change substrate a few times/year if not bioactive.
• Provide fresh water bowl; change every few hours due to fouling :contentReference[oaicite:19]{index=19}.

4. Nutrition & Feeding

Omnivorous diet: ~60% plant, 40% animal protein :contentReference[oaicite:20]{index=20}.

4.1 Juvenile:

• Daily feeding of insects, snails, worms, veggies, fruit, pellets. 

4.2 Adult:

• Feed every 2–3 days for adults, every day for juveniles :contentReference[oaicite:21]{index=21}.
• Include dark greens (collards, dandelion), squash, bell peppers, occasional fruit :contentReference[oaicite:22]{index=22}.
• Protein: earthworms, snails, canned meats, high-quality pellets :contentReference[oaicite:23]{index=23}.
• Supplement calcium + D3 every 2–3 meals for adults, more often for juveniles :contentReference[oaicite:24]{index=24}.
• Never feed citrus, avocado, rhubarb; avoid high-sodium meats :contentReference[oaicite:25]{index=25}.

5. Health & Veterinary Needs

• Annual reptile vet exam; monitor weight, shell, eyes, respiratory health.
• Watch for parasites—fecal exams yearly.
• Maintain proper temperature, humidity, and UV to prevent metabolic disease.
• Handle carefully to avoid bite risk—though non-venomous, bites hurt :contentReference[oaicite:26]{index=26}.

6. Reproduction & Lifespan

• Ovoviviparous—give live birth; litter size varies from 5–25 depending on subspecies :contentReference[oaicite:27]{index=27}.
• Sexual maturity ~3 yrs; mating can be aggressive :contentReference[oaicite:28]{index=28}.
• Lifespan: 15–30+ years; shinglebacks live up to 50 years :contentReference[oaicite:29]{index=29}.

7. Common Health Issues & Preventive Care

• Respiratory infections—watch for wheezing, open-mouth breathing; often humidity-related.
• Shedding issues—retain skin around toes/head; use humid hides to assist :contentReference[oaicite:30]{index=30}.
• Obesity—monitor diet balance.
• Parasites—regular checks and deworming as directed by your vet.

8. Enrichment & Handling Safety

• Provide logs, hides, substrates for natural exploration :contentReference[oaicite:31]{index=31}.
• Regular, gentle handling builds trust; skip handling when stressed.
• Always supervise children with the skink.
• Quiet environment reduces stress and supports well-being.
