Blue-Tongue Skink Care Guide: Housing, Heat, and Diet
Blue-tongue skinks are hardy, ground-dwelling omnivores that make calm, long-lived pets. This guide covers the wide floor space they need, the basking heat and UVB gradient to set up, and a balanced plant-heavy diet, so you can build a healthy, low-stress enclosure from day one.
Quick answer
A blue-tongue skink needs a large, floor-based enclosure with a warm basking spot around 35-38°C, a cooler end near 24-26°C, low-level UVB, and a deep loose substrate to burrow in. Feed a varied omnivore diet that is mostly vegetables and greens with a smaller share of protein and fruit. Get these three things right and skinks are one of the most forgiving lizards to keep.

Housing and space
Blue-tongue skinks are heavy-bodied and terrestrial, so floor space matters far more than height. An adult needs an enclosure of at least 120 x 60 cm of floor area; bigger is always better. Choose a front-opening wooden or PVC vivarium, which holds heat and humidity more steadily than an open-topped glass tank.
Provide a substrate you can dig into, such as cypress mulch, aspen, or a soil-and-sand mix, a few inches deep so the skink can burrow. Add at least two hides, one on the warm side and one on the cool side, plus a sturdy water dish large enough to soak in.
A long, wide floor plan with a clear warm-to-cool gradient matters more than height for a ground-dwelling skink.
Heat, light, and UVB
Reptiles cannot make their own body heat, so you build a temperature gradient and let the skink choose. Aim for a basking surface of 35-38°C at one end, dropping to 24-26°C at the cool end, with a night-time drop into the low 20s. Use a thermostat-controlled overhead heat source and check temperatures with a probe or infrared thermometer, never by guessing.
Provide a UVB tube running about two-thirds the length of the enclosure. UVB helps the skink produce vitamin D3 and absorb calcium, preventing metabolic bone disease. Replace UVB bulbs every 6-12 months as directed, because output fades long before the light stops glowing.
Diet and feeding
Blue-tongue skinks are omnivores. A good adult plate is mostly leafy greens and vegetables, with a smaller portion of protein and only occasional fruit. Suitable greens include dandelion, endive, and collard; vegetables like squash, carrot, and bell pepper add variety. Protein can come from cooked lean meat, insects, or a quality low-fat dog food used sparingly.
Aim for roughly a plant-heavy plate with a smaller share of protein, dusted with calcium a few times a week.
Dust food with a calcium supplement several times a week and a multivitamin less often. Adults typically eat every 2-3 days; younger skinks eat more frequently. Avoid feeding avocado, rhubarb, and anything salty or processed.
Handling and daily care
Blue-tongues are famously tolerant and often become tame with gentle, regular handling. Support the whole body, keep sessions short at first, and let the skink come to associate you with calm routines. Spot-clean waste daily and do a full substrate change on a regular schedule.
Quick FAQs
Do blue-tongue skinks need UVB? Yes. While some keepers raise them without it using dietary D3, low-level UVB is safer and supports natural behaviour and bone health.
Can I keep two skinks together? No. They are solitary and can injure each other over territory and food. House them separately.
Why is my skink hiding all the time? New skinks often hide while settling in. Persistent hiding with no basking can also mean temperatures are wrong — check your gradient.
How big a tank do I need long term? Plan for at least 120 x 60 cm of floor space for an adult, and treat that as a minimum rather than a target.
