Blue Tongue Skink
Scientific Name: Tiliqua scincoides (most common species in captivity, though several regional species exist).
Why the Name: They’re named for their iconic bright blue tongue, which they flash to startle predators.
Size & Lifespan: 18–24 inches; 15–20+ years with proper care.
Native Habitat: Australia, Indonesia, and surrounding regions—grasslands, scrublands, forests, and semi-arid areas.
Behaviors: Calm, slow-moving, curious, and rely heavily on their sense of smell. Will hiss or puff when threatened.
Group or Solitary: Solitary—house alone.
Active Period: Diurnal.
Why It Looks How It Looks: Stout body and short legs help them burrow; blue tongue is a defense display; smooth scales prevent dehydration.
Fun Facts:
– Juveniles drop their tails less readily than many lizards.
– Known as one of the best pet lizards due to temperament.
– They mimic venomous snakes by hissing loudly and flattening their bodies.
ENCLOSURE
An adult Blue Tongue Skink thrives best in a minimum 4x2x2 ft enclosure, larger preferred. Use cypress mulch, orchid bark, or a soil/mulch mix that maintains humidity but allows burrowing.
Provide a basking area of 95–100°F, a warm side around 85°F, and a cool side 72–78°F. Night temps can drop to 68–70°F safely.
Humidity varies by species: Australian types prefer 30–45%, Indonesian types 50–70%—adjust accordingly.
UVB is required, ideally 12% T5 HO.
Ideal temperature range: 70–100°F. They tolerate brief drops to mid-60s or spikes to 105°F but avoid extremes.
DIET & HYDRATION
Blue Tongue Skinks are omnivores and need a balanced weekly rotation.
Weekly Feeding Schedule (Adult):
– Feed 3–4x per week.
– Each feeding: roughly 1–2 tablespoons depending on size.
Juveniles: Feed daily small meals.
Staple Foods:
– Greens: collard, mustard, dandelion, squash, green beans.
– Protein: cooked chicken, eggs, snails, roaches, superworms, high-quality dog food (wet), or reptile omnivore diets.
– Fruits (small amounts): berries, mango, papaya.
Treats:
– Mealworms, superworms, low-fat canned cat food, hard-boiled egg.
No Feed / Toxic:
– Avocado, onion, garlic, rhubarb, iceberg lettuce, fireflies.
Hydration:
Provide a shallow water dish refreshed daily; mist lightly if keeping an Indonesian species. They drink readily and may soak.
Supplements:
– Calcium with D3 1–2x weekly.
– Multivitamin once weekly.
Diet-Related Behaviors:
They may “smell-test” food and take time to begin eating; some individuals prefer variety.
HEALTH
Common concerns include respiratory infections from low temps, mites, internal parasites, metabolic bone disease (if no UVB), and dehydration in arid species.
No severe zoonotic diseases, but poor husbandry can lead to fatal issues like MBD or severe RI. Regular fecals recommended.
HANDLING
Blue Tongue Skinks are naturally calm and tolerate handling extremely well when accustomed.
Too much rough handling can stress them, especially juveniles, but adults are sturdy.
Handling Tips:
– Support the entire body with two hands.
– Avoid sudden movements.
– Allow them to walk hand-to-hand slowly.
– They rarely bite but may huff or puff when unsure.
For Shows:
Yes—Blue Tongue Skinks are excellent show animals. Great with kids, calm, rarely messy, tolerate heat, and can do multiple shows per day.
They meet all show-animal requirements.
