Profile description
The Eastern Blue-tongued Lizard is native to eastern Australian woodland, grassland, garden and suburban habitat, using logs, litter, rocks and shallow shelters. Usually 45 to 55 cm total length with a heavy body and short limbs. Expected captive lifespan is often 15 to 20 years and potentially longer. The Eastern Blue-tongued Lizard is a terrestrial, generally calm and robust skink that uses a blue tongue display when alarmed. Individuals can still bite strongly and should be lifted with full-body support. It is an omnivore requiring varied vegetables, leafy greens, limited fruit and suitable animal protein. Dog or cat food should not become the sole diet.
Skinks are smooth-scaled lizards with diverse feeding and social strategies. The selected species are terrestrial or semi-climbing and need enough floor area to walk, explore and choose between secure microclimates. They often hide illness until appetite, weight, movement or breathing has changed substantially. Routine records of body weight, food intake, shedding, faeces and reproductive activity are therefore more reliable than casual visual observation.
Obesity, overgrown claws, dental disease and calcium imbalance are common when the enclosure is small and the diet is soft, rich or poorly balanced.
Eastern Blue-tongued Lizard (Tiliqua scincoides) is a native reptile included on the Queensland Government's current keeper-licence species search; the listed Queensland requirement is Queensland Standard Licence. State and territory rules for the Eastern Blue-tongued Lizard, including licence class, possession, breeding, movement and records, differ and can change. Obtain the Eastern Blue-tongued Lizard only from a lawful captive-bred source; native reptiles must not be taken from the wild and exotic reptiles cannot be imported as pets.
First-time reptile owner tips
Practical preparation for welcoming this reptile into your care.
Care requirements
Provide broad floor space, secure hides at both warm and cool ends, a basking site, species-appropriate UVB and a substrate that permits safe digging. Weigh food portions, encourage natural foraging and avoid excessive high-fat animal protein. Use broad floor space, naturalistic cover and hides at more than one temperature. Substrate must be clean, non-toxic and appropriate for digging without creating an impaction or dust hazard. Feed on a clean surface or in a dish where needed. Exercise and foraging should be designed into the enclosure because a skink can maintain appetite while becoming progressively obese and weak.
Follow the Eastern Blue-tongued Lizard's documented species diet when balancing invertebrate, plant or other appropriate foods. For the Eastern Blue-tongued Lizard, use safe sources, sensible portions and measured supplementation rather than assuming every lizard has identical nutritional needs. Provide the Eastern Blue-tongued Lizard with fresh water and species-appropriate humidity or retreat options without keeping an arid enclosure uniformly damp.
A reptile-experienced veterinarian should assess the Eastern Blue-tongued Lizard after acquisition, with routine reviews at least annually thereafter. Record the Eastern Blue-tongued Lizard's weight, body condition, meals, faecal output, sheds, activity, basking and reproductive events. Quarantine a new Eastern Blue-tongued Lizard in a separate room with dedicated equipment for a veterinarian-directed period before sharing air, water, furnishings or tools. Good Eastern Blue-tongued Lizard hygiene supports the rest of the husbandry program. Remove the Eastern Blue-tongued Lizard's waste promptly, clean food and water containers, disinfect with a reptile-safe method and rinse thoroughly. Wash hands after handling the Eastern Blue-tongued Lizard or its enclosure, supervise children and vulnerable people, and keep the reptile and its equipment away from food preparation.
Urgent veterinary signs in the Eastern Blue-tongued Lizard include open-mouth or laboured breathing, collapse, seizures, severe weakness, prolapse, uncontrolled bleeding, major burns, inability to pass eggs and persistent vomiting or regurgitation.
