What is a Blue-Tongue Skink?

A Blue-Tongue Skink is a intermediate-level lizard from Dry forests. Adults reach 18–24 in and can live 15–20 (reports of 30+ years with excellent care) years in captivity — a long-term commitment. A robust, dog-like omnivore from Australian grasslands with a famously docile temperament — an excellent step-up from beginner species that rewards its keeper with decades of companionship.

What size enclosure does a Blue-Tongue Skink need?

The minimum enclosure for an adult Blue-Tongue Skink is 4×2×2 ft (48×24×24 in; terrestrial — floor space priority over height). Bigger is always better — Blue-Tongue Skinks benefit from extra space to thermoregulate and express natural behaviours.

What you need:

  1. Secure, well-ventilated enclosure — screen top or side ventilation; tight-fitting lid.
  2. Thermostat-controlled basking lamp — dimmer or proportional thermostat; never a heat rock.
  3. Warm and cool hides — at least one hide on each end of the thermal gradient.
  4. Water bowl — shallow, heavy-bottomed; changed daily.
  5. Appropriate substrate — species-appropriate depth; moist hide in one corner.

What temperature does a Blue-Tongue Skink need?

Provide a basking spot of 105–115°F and a cool side of 70–80°F. Measure surface temperature with an infrared thermometer. Use a high-wattage basking bulb on a dimmer or thermostat — never a heat rock. Drop to 65–75°F at night to support digestion and immune function.

Do Blue-Tongue Skinks need UVB?

Blue-Tongue Skinks need moderate UVB — target UVI 3.0–4.0. Use a T5 HO 6% or 12% tube mounted at the correct distance above the basking spot. Use the UVB Calculator above — it accounts for enclosure height and basking platform height. Replace bulbs every 12 months.

What humidity does a Blue-Tongue Skink need?

Maintain humidity at 40–60%. Moderate humidity suits most commonly available substrates. Maintain a moist hide in one corner to support proper shedding. A digital hygrometer is essential.

What do Blue-Tongue Skinks eat?

Blue-Tongue Skinks are omnivores — diet composition changes significantly with age. Juveniles (0–8 mo): 70–80% protein, 20–30% plant matter; offered daily to 3× weekly. Adults (8+ mo): ~50% protein, 50% plant matter; offered 1–2× weekly. Protein sources: dubia roaches, crickets, earthworms, snails, canned dog/cat food (low sodium), ground turkey. Plant matter: dark leafy greens (collard, dandelion, endive), squash, bell peppers, snap peas. Avoid high-oxalate foods. Dust feeders with calcium+D3.
