Schneider's Skink — care sheet

Beginner–Intermediate. A hardy, forgiving desert skink that tolerates handling well, so it's a genuinely good "first big lizard." The catch is that it needs real space, a deep sand bed to burrow in, a hot basking spot, and UVB done properly — get those four things right and the rest is easy.

Omnivore that leans insectivore — think roughly an 80/20 insect-to-plant split. Staple feeders: dubia/discoid roaches, crickets, black soldier fly larvae, plus occasional mealworms, superworms, hornworms, and silkworms. Add a modest share of leafy greens (collard, mustard, turnip, dandelion) and small amounts of fruit/veg. Juveniles eat daily; adults eat 2–3 times a week, offering what they'll finish in about 5–10 minutes. Gut-load feeders well.

Aim for a horizontal, floor-space-first enclosure. 36"L x 18"W x 18"H (a "3x2") is the practical minimum for a small adult under about 14 inches; a full-grown adult does much better in 48"L x 24"W x 24"H (a "4x2x2," ~120 gallon). Bigger is always better — these are active, ground-cruising diggers. Floor area matters far more than height.

Modern best practice is a basking surface of 105–115°F (41–46°C), measured with an infrared temp gun on the actual basking rock or sand under the lamp — not a stick-on dial. (Older care sheets list 95–100°F; the higher modern range better matches this hot, sun-loving desert species. Provide the gradient and let the skink choose.)

75–85°F (24–29°C) on the cool end, giving a true thermal gradient across the enclosure so the skink can self-regulate.

A natural night drop is fine and healthy; temperatures should not fall below about 65°F (18°C). No nighttime light is needed — use a non-light heat source (like a thermostat-controlled ceramic emitter) only if your room gets colder than that.

Yes — provide UVB. Despite old claims that skinks "don't need it," this is a diurnal, sun-basking desert species and does best with UVB plus dietary D3. Use a linear T5 HO tube run along part of the enclosure: for a 16–18" tall enclosure, an Arcadia Forest 6% or Zoo Med ReptiSun 5.0 mounted about 7–9" above the basking surface; for a taller ~24" enclosure, an Arcadia Desert 12% or Zoo Med ReptiSun 10.0 about 13–15" above the basking spot (further if there's no mesh in between). Target a basking-zone UVI around 3–4. Replace T5 tubes about every 12 months.

Low — keep the ambient average under about 50%, measured with a digital probe hygrometer; many keepers run it lower (30–40%). This is a dry-country species and chronic damp invites skin and respiratory problems. Offer a humid hide or lightly moisten the deeper substrate layer to help with shedding rather than misting the whole enclosure.

A deep, diggable, sandy substrate at least 4 inches (10 cm) deep so the skink can burrow and tunnel — this is essential natural behavior, not optional decoration. A washed play-sand / topsoil blend or a reptile desert sand (e.g., ZooMed ReptiSand, Exo Terra Desert Sand) works well; deeper is better. Avoid loose calci-sand and keep the bed on the dry side. Spot-clean regularly and refresh fully every few months.

Dust feeders with a quality calcium/vitamin supplement. A simple reliable routine is an all-in-one like Repashy Calcium Plus LoD lightly dusted on feeders, or plain calcium (with D3) on most feedings plus a reptile multivitamin about once a week. Because they get UVB, use lower-D3 products and don't over-supplement.

Typically 12–18 inches (30–46 cm) total length as adults, occasionally larger; roughly half of that is tail. Wikipedia gives a wild snout-to-vent length around 6.5 in (16.5 cm) plus an 8 in (20 cm) tail. They're heavy-bodied and muscular for their length.

15–20 years with good care; many sources cite 15+ years and some individuals live longer. This is a long-term commitment, not a short-lived starter pet.

See a reptile or exotics vet if you notice: Soft jaw or limbs, tremors, swollen or bowed legs, or repeated unexplained fractures — possible metabolic bone disease; see an exotics vet and review UVB and calcium.; Not eating for an extended period, obvious weight loss, or a suddenly sunken/thin body — get it checked, especially if temps and setup look right.; Open-mouth breathing, wheezing, bubbling, or mucus around the nose/mouth — possible respiratory infection (often from too-cool or too-damp conditions).; Retained shed, especially rings of stuck skin on toes or the tail tip that can cut off circulation — needs help and a humidity review.; Runny, bloody, or persistently abnormal droppings, or visible parasites — collect a fresh fecal sample for the vet.; Lethargy, lopsided posture, dragging a limb, or any wound, burn, or swelling that doesn't improve.; Straining, or a female that seems gravid but can't pass eggs (egg-binding) — this is an urgent exotics-vet visit..
