Husbandry requirements

Steppe Tortoise / Russian Tortoise — origin: Central Asia: arid and semi-desert steppes of Kazakhstan, Uzbekistan, Turkmenistan, Afghanistan, Iran, Pakistan and north-western China..

Terrarium temperature gradient

Night min15 °C
Cool side20–25 °C
Warm side28–32 °C
Basking spot35–40 °C

A heliophilic species of open habitats: a genuine basking hot spot at 35-40 °C is essential, with a strong thermal gradient towards a cool side at 20-25 °C. The night-time drop is well tolerated (down to ~10-15 °C without supplementary heating). Controlled hibernation at 4-8 °C, in a healthy, fasted animal, is natural and beneficial but must be supervised by an exotic-animal vet.

Enclosure (adult)
120 × 60 × 40 cm

An open tortoise table or a large, well-ventilated indoor terrarium; a secure outdoor pen is strongly recommended in fine weather.

A minimum for a single adult; bigger is always better, especially the floor space. Smooth, sufficiently high walls (a climber) and a buried barrier of at least 20-30 cm (a burrower). Avoid closed, humid, poorly ventilated vivariums. The ideal remains a sunny, dry outdoor pen, safe from predators.

Humidity
30–50 %

An overall dry environment (arid steppe). Avoid stagnant humidity, a factor in respiratory infections and shell rot. Nonetheless provide a slightly humid hide (microclimate) and regular baths, especially for juveniles, to limit dehydration and pyramiding.

Substrate
Earth/sand mix (non-fertilised compost + silica sand)Loam-type soil allowing diggingDry meadow hay as a surface layer

A dry, loose and deep substrate (at least 10-15 cm) to allow the natural digging behaviour. Ban resinous shavings (cedar, pine), dusty substrates and any material that retains moisture. Remove droppings and food remains regularly.

UVB
Recommended

Essential. Provide strong desert-type UVB (T5 HO tube 10-12 % / UV index 5.0-6.0) covering the living area, or exposure to real sunlight outdoors. Replace tubes/lamps according to the manufacturer's recommendations (UV output drops before the visible end of life). A lack of UVB rapidly leads to osteofibrosis (MBD).

Water source
Always available

Provide at all times a shallow, easily accessible dish of clean water (to drink and to soak without risk of drowning). Offer regular lukewarm baths (10-20 min), 1 to 2 times/week for adults and more frequently for juveniles, for hydration and gut transit.

Feeding & health

Diet

Strict herbivore — No animal prey

A fibre-rich, protein-poor diet: grasses, graminoids, wild 'weed' plants (dandelion, plantain, clover in moderation, mallow, occasional alfalfa), edible flowers and a few succulents. Ban fruit (exceptional at best), animal proteins, dog/cat kibble and excess water-rich cultivated leafy vegetables. Supplement with calcium (cuttlebone ad libitum) and provide suitable UVB exposure. A diet that is too rich/moist promotes pyramiding and stones.

Breeding
Oviparous

Clutch 2–6 eggs/young. Small clutches of 2 to 6 eggs that are relatively large compared with the female's size, often in several clutches per season. Breeding is generally triggered by a winter cooling cycle (hibernation) followed by rising temperatures. Artificial incubation of about 60 to 90 days depending on temperature; sex influenced by the incubation temperature.

Health watch points
  • Respiratory infections (rhinitis/pneumonia) linked to cold damp and poor ventilation
  • Osteofibrosis / metabolic bone disease (MBD) from UVB or calcium deficiency or a Ca/P imbalance
  • Carapace pyramiding (abnormal growth) due to a diet too rich/high in protein and to dehydration
  • Internal parasitism (nematodes, pinworms) very common in imported wild-caught animals
  • Chronic bladder stones and dehydration from lack of water and an unsuitable diet

Frequently asked questions

Answers to the most common questions about keeping the steppe tortoise / russian tortoise.

What size and distinctive features does the adult Russian tortoise have?▾
It stays modest in size, with a carapace usually 13 to 20 cm, rarely beyond 23 cm, females being larger than males. It is recognisable by its flat, rounded shell, its only 4 claws on the front legs (other Testudo have 5) and the horny tip at the end of its tail.
Is it a tortoise suited to a first-time keeper?▾
It is considered suitable for a beginner to intermediate profile, thanks to its robustness and hardy character. This does not, however, exempt you from precisely meeting its needs for heat, UVB and a dry, fibrous diet, failing which health problems arise quickly.
What enclosure does it need and how do you prevent escapes?▾
Provide at least 120 x 60 cm of floor space and 40 cm of height for a single adult, in an open tortoise table or a large, well-ventilated terrarium, with a secure outdoor enclosure strongly recommended in fine weather. It is an expert climber and burrower: you need fairly high, smooth walls, as well as a buried barrier of at least 20 to 30 cm.
What temperature and basking spot should be reproduced?▾
A genuine basking spot at 35-40 °C is essential, with a strong gradient toward a cool side at 20-25 °C and a warm side at 28-32 °C. The nighttime drop is well tolerated down to 10-15 °C, and a controlled hibernation at 4-8 °C in a healthy, fasted animal is natural but must be supervised by an exotic-pet veterinarian.
Does it need a lot of humidity and which substrate is best?▾
No: its natural steppe environment is generally dry, with a target humidity of 30 to 50 % on a dry, loose substrate such as a soil-sand mix, at least 10-15 cm deep to allow burrowing. Stagnant humidity is precisely what to avoid, as it promotes respiratory infections; a slightly humid hide and regular baths in juveniles are enough to prevent dehydration and pyramiding.
What does a Russian tortoise eat day to day?▾
It is a strict herbivore, with no animal prey: its menu should be high in fibre and low in protein, based on herbs, grasses and weeds such as dandelion, plantain or mallow, with a little occasional alfalfa and edible flowers. Fruit, animal protein and dog or cat kibble must be banned, as they promote pyramiding and stones.
Why is UVB so crucial for this species?▾
Native to arid, very sunny steppes, it needs strong desert-type UVB (T5 HO tube 10-12 %, UV index 5.0-6.0) covering its living area, or exposure to real sunlight outdoors. Its absence quickly leads to osteofibrosis, and the lamp must be replaced according to the manufacturer's recommendations even if it still gives off visible light.
How should water and hydration be managed?▾
A shallow dish of clean water should be available at all times for drinking and soaking. Lukewarm baths of 10 to 20 minutes, once or twice a week in adults and more often in the young, nicely complement hydration and gut transit.
How long does it live and what commitment does that represent?▾
It commonly lives 40 to 60 years, and some individuals even exceed 70 to 80 years in well-managed captivity. It is therefore a commitment of several decades to consider seriously before acquisition.
Can it be bought and kept without formalities?▾
No, the species is listed in CITES Appendix II (EU Annex B) and its keeping or transfer requires legal documentation. Many individuals in the trade are unfortunately stressed, parasitised wild-caught animals: it is better to favour a captive-bred, documented animal.
How does it reproduce in captivity?▾
It is the winter cooling cycle (hibernation) followed by rising temperatures that generally triggers breeding. Clutches stay small, 2 to 6 eggs that are relatively large compared with the female's size, often laid in several batches per season, with an incubation of 60 to 90 days whose temperature influences the sex.
What are the main risks to its health?▾
Respiratory infections linked to damp cold and poor ventilation are common, as is osteofibrosis in cases of UVB or calcium deficiency. Also watch for pyramiding linked to an overly rich diet, internal parasitism in imported individuals, and bladder stones linked to a lack of water.
