Sulcata Tortoise Care

What is a Sulcata Tortoise?

A Sulcata Tortoise is a advanced-keeper tortoise from Sahel belt of sub-Saharan Africa. Adults reach 24–30 in shell length; 80–150 lb (males larger; exceptional specimens exceed 200 lb) and can live 55–100+ years in captivity — a long-term commitment. The third-largest tortoise in the world, sulcatas grow to over 100 lb and require an outdoor enclosure as adults, a strictly grass-based herbivore diet with no fruit, and strong UVB — seriously underestimated as a beginner pet.

What size enclosure does a Sulcata Tortoise need?

The minimum enclosure for an adult Sulcata Tortoise is Outdoor enclosure required for adults — minimum 100 sq ft per tortoise; 200+ sq ft strongly preferred by experienced keepers. Must have warm shelter/hide, secure burrowing-proof perimeter (walls 12+ in above ground and 12 in below), and year-round access to warmth in cool climates. Indoor housing only appropriate for hatchlings/juveniles under ~6 in shell.. Floor space is the priority for terrestrial tortoises. Adults typically need outdoor housing to meet roaming, thermoregulation, and grazing needs.

What you need:

1. Outdoor enclosure (100+ sq ft) — adults need outdoor space; secure burrowing-proof walls.
2. Warm shelter/hide — insulated box or heated indoor space for cool nights.
3. Deep substrate — 6–12 in minimum for natural burrowing behaviour.
4. Basking lamp + UVB — over the primary basking area; T5 HO 12% or 14% tube.
5. Grazing area / browse — grasses, edible weeds; sunlight exposure is essential.

What temperature does a Sulcata Tortoise need?

Provide a basking spot of 100–105°F and a cool side of 75–85°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 Sulcata Tortoises need UVB?

Yes — Sulcata Tortoises need high UVB (target UVI 3.0–6.0). Use a T5 HO 12–14% tube (e.g., Arcadia Desert 12% or Zoo Med ReptiSun 10.0) mounted directly above the basking spot. Use the UVB Calculator above to confirm mounting height and basking platform height. Verify with a Solarmeter 6.5 and replace bulbs every 12 months.

What humidity does a Sulcata Tortoise need?

Maintain humidity at 30–50 adults%. Keep the enclosure on the drier side. Use a digital hygrometer — guessing humidity is a common beginner mistake that leads to respiratory problems and dysecdysis (difficult shedding). A digital hygrometer is essential.

What do Sulcata Tortoises eat?

Sulcata Tortoises are strict herbivores — grasses, hay, and edible weeds form the bulk of the diet. High-fiber, low-protein, grass-based diet: ~80% grasses and hay (Bermuda, orchard, timothy, buffalo) + edible weeds/wildflowers (dandelion, plantain, clover, mallow) + dark leafy greens (collard, mustard, turnip greens). Calcium supplementation essential. AVOID: all fruit (sugar disrupts gut flora), any animal protein/dog food/cat food, spinach, rhubarb, bread, dairy, avocado, and toxic plants. NO fruit is the critical rule for beginners. Never offer any animal protein, insects, or rodents — these cause serious organ damage in herbivorous species.

1. Grasses and hay — the bulk of the diet (Bermuda, orchard, timothy grass, timothy hay).
2. Edible weeds and wildflowers — dandelion, plantain, clover, mallow.
3. Dark leafy greens — collard, mustard, turnip greens in moderation.
4. No animal protein — never offer insects, rodents, or any meat; causes serious organ damage.
5. Fresh water daily — in a wide, shallow dish changed every day.

Can you house Sulcata Tortoises together?

Caution — males are territorial and will fight; females can co-habit with ample space. House separately if possible; multiple animals need substantially enlarged space and extra resources. Solitary housing is simplest and lowest-risk. Allow new animals at least 2 weeks to settle in before handling. Support the body fully — avoid grabbing from above, which triggers a defensive response.

Are Sulcata Tortoises good for beginners?

Sulcata Tortoises are an advanced species for experienced keepers. Research thoroughly, set up the enclosure fully, and source from a reputable captive-bred breeder before acquiring. Animals cost 50–300 (hatchlings, common captive bred); 300–600 (juveniles); adults 2,000–4,000+ depending on size and source.
