Indian Star Tortoise — care sheet

Advanced. Not a beginner tortoise. Star tortoises are sensitive to husbandry errors, need a warm gradient with a big basking spot AND carefully managed moisture (dry-but-not-arid, with humid hides), and grow slowly over decades. On top of that, they're CITES Appendix I and the single most-confiscated tortoise in the illegal trade, so sourcing a legal, captive-bred animal is itself a real hurdle. Great for an experienced keeper who has room and patience; frustrating and often fatal for a first tortoise.

A high-fibre grazing herbivore: think roughly 90% grasses and weeds, ~10% leafy greens. Good staples include lawn grass and hay, dandelion, clover, plantain (Plantago), chickweed, honeysuckle, sow thistle, mulberry and grape leaves, watercress, rocket, kale, spring greens and other dark leafy greens, plus opuntia (cactus) pads. Use The Tortoise Table to check any plant. Skip regular fruit and high-protein or high-sugar foods; feed low-and-slow. Provide constant fresh water in a shallow dish and soak young tortoises regularly.

Bigger is always better; adults do best with a large open tortoise table or, ideally, a secure outdoor pen in warm weather. As a practical indoor minimum for one adult, aim for at least ~16 sq ft of floor (e.g. a 4 x 4 ft pen) with 8 in solid walls; a 4 x 2 ft table is the bare floor of what one adult can tolerate. Outdoors, a 4 x 4 ft pen is a starting minimum and much larger is preferred. Double the space for any additional tortoise, and never house with other species.

A hot basking spot of about 95-105°F (35-40°C) under a halogen/incandescent flood; some sources give 90-100°F (32-38°C). Position the heat lamp so the shell top sits roughly 8+ in below it and the tortoise can move away.

A warm ambient of about 75-80°F (24-27°C) at the cool end, so there's a clear gradient across the floor. The cool side should not sit cold-and-damp; chilled, wet conditions are dangerous for this species.

A modest night drop is fine and even helpful: down to about 60-70°F (15-21°C) is widely used indoors, and outdoor adults tolerate short dips to around 50°F (10°C). Avoid heating that never lets the temperature fall; a cool-but-not-cold night is normal.

Strong UVB is non-negotiable for shell and bone health. Use a high-output linear tube such as a Zoo Med Reptisun 10.0 T5 HO or Arcadia 12% T5 HO running most of the enclosure length, 10-12 hours a day. Mount per the maker's guidance for the fixture (roughly 6-8 in above the shell for an unmeshed Zoo Med hood, ~17-18 in for an Arcadia ProT5 reflector) and replace the tube about every 12 months even if it still glows. Best of all is real unfiltered sunlight outdoors, which needs no artificial UVB.

This is the part people get wrong in both directions. Star tortoises are NOT true desert animals; their homeland has a humid monsoon season, so they need more moisture than a Mediterranean tortoise but not a swamp. Aim for roughly 40-75% ambient humidity for adults, with the higher end and a humid hide especially important for hatchlings and juveniles (often 70-80% in their microclimate) to prevent shell pyramiding. Pair humid hides and misting with a well-ventilated, not soggy, main floor.

A deep, moisture-holding but breathable substrate: topsoil, coir/coconut fibre, or a topsoil-play-sand mix (around 60/40), often topped with grass hay. Provide depth at least as deep as the tortoise's legs are long (aim for 6+ in / 15+ cm) so it can dig and burrow to self-regulate moisture. Spot-clean daily and change fully on a regular schedule. Avoid dusty, resinous or dyed beddings.

Dust food with a phosphorus-free calcium (calcium carbonate) most feeds, and offer a cuttlebone to gnaw. A balanced reptile multivitamin (with vitamin A and D3) a couple of times a week supports animals without unfiltered sunlight; go lighter on vitamins for well-sunned adults. Don't over-supplement D3 if the tortoise has strong UVB or real sun.

Females are notably larger than males. Males reach roughly 15-20 cm (6-8 in) shell length; females about 25-30 cm (10-12 in), with a record female near 38 cm (15 in). Weight ranges from about 1 kg up to 6.6 kg (2-14+ lb) depending on sex and size.

A multi-decade commitment. Well-kept captives commonly live 30-50+ years, and wild lifespans are estimated at 35-80 years. Long-lived-record claims (approaching 80) exist but are poorly documented; plan realistically for this tortoise to outlast a large chunk of your life and to need a plan for its future.

See a reptile or exotics vet if you notice: Runny or bubbly nose, mouth bubbles, wheezing, or open-mouth/labored breathing - possible respiratory infection; see an exotics vet promptly.; Soft, flexible or misshapen shell, bendy or swollen limbs, or a beak that won't close - possible metabolic bone disease.; Pitting, soft spots, weeping, foul smell or discoloured areas on the shell - possible shell rot/infection.; Swollen eyelids, closed or discharging eyes, or loss of appetite with lethargy - could signal vitamin A deficiency or infection.; Not eating for an extended period, ongoing weight loss, or a sunken/dull-eyed 'dehydrated' look.; Straining, a female restlessly digging and going off food (possible egg-binding), or straining to pass stool.; Any prolapse of tissue from the tail/vent, or a serious shell crack or injury - treat as urgent.; Persistent diarrhoea or visible worms - get a faecal parasite check..
