Russian Tortoise

Russian Tortoise Care Guide

Testudo horsfieldii

Russian tortoises are wonderful little tortoises with big personalities. Ranging from 5–8 inches in length and weighing about half a pound to two and a half pounds (300–1500 grams), they are one of the smallest tortoise species available as pets. This species is native to dry steppe ecosystems across central Asia. Males can be distinguished from females by their longer, thicker tail with a notable spur (modified scale) at the tip; males are also typically smaller in body size than females. This species can live 40–50+ years as pets.


Enclosure

Outdoor enclosures are preferred for most tortoises. Minimum recommended size for adults is 4 ft × 6 ft. Enclosure sides should be opaque and smooth to prevent climbing and escape attempts, and must be predator-proofed. Fencing should be buried at least 12 inches deep to prevent burrowing underneath. Wire, hardware cloth, chain link, and woven wooden fences are not recommended.

For indoor housing, a “tortoise table” setup or large storage tub is recommended over glass aquariums — these allow better ventilation and prevent the tortoise from repeatedly attempting to walk through the clear glass.

Provide hides at both the warm and cool ends — cork rounds, hollow logs, caves, or overturned planter pots all work well. A humid hide filled with damp sphagnum moss is recommended and especially important for hatchlings and juveniles to promote normal shell growth and development. Live plants inside the enclosure should be edible and non-toxic. Outdoors, provide access to both direct sunlight and shade, along with artificial burrows for cool, humid retreat on hot days and insulation during winter.

Substrate

Avoid gravel and sand — these may be ingested and cause impactions. For indoor enclosures, cypress mulch, coconut fiber/Eco Earth, and organic topsoil are good choices. Always feed on a flat flagstone, tile, or similar surface rather than directly on substrate to prevent accidental ingestion.

Temperature

Indoors:

  • Basking area: 95°F
  • Cool end: 75–80°F
  • Nighttime: 65–70°F

Provide heat with basking bulbs, ceramic heat emitters, or radiant heat panels. Hot rocks should be avoided. Monitor temperatures with a digital or infrared thermometer; a thermostat is recommended to maintain appropriate temperatures.

Outdoors, tortoises will retreat into cooler burrows during hot weather. Brumation begins when temperatures drop below 50–60°F.

Lighting

Russian tortoises require UVB lighting to process calcium properly. For indoor tortoises, use high-output fluorescent or mercury vapor bulbs rated for desert reptiles — such as the ReptiSun 10.0 or Arcadia 12%. Place UVB lighting no more than 12–18 inches from the basking site (follow manufacturer guidelines; monitoring UV output with a Solarmeter is recommended). Connect to a timer — approximately 14 hours of light in summer and 10 hours in winter. Replace bulbs every 6–12 months — they stop producing UVB long before they stop emitting visible light. Outdoor tortoises receive all the UVB they need from the sun.

Humidity & Water

Maintain 40–60% humidity, measured with a digital hygrometer. Hand misting can help maintain appropriate levels. Soak tortoises in shallow warm water for 15 minutes 2–3 times weekly to encourage drinking, urination, and defecation. A large, flat, shallow water bowl can be provided indoors and should be changed and cleaned daily. Do not leave standing water in outdoor enclosures for more than a day or two — stagnant water can harbor protozoan parasites that may cause illness.

Diet

Russian tortoises are herbivores. Outdoor enclosures should be richly planted with grasses (Bermuda, rye, fescue), spurges, hibiscus bushes, and mulberry trees. Romaine lettuce, green or red leaf lettuce, escarole, kale, collard greens, mustard greens, turnip greens, and other dark leafy greens can be fed supplementally. Juveniles and indoor tortoises need daily salads. Avoid overfeeding low-fiber produce or fruit, which can cause diarrhea.

Tortoises can also be offered Mazuri LS or ZooMed Grassland Tortoise Pellets softened in water every 2–3 days.

Feed daily (staples): shrubs, weeds, forbs, alfalfa, grass hay (timothy), cactus pad/leaf (prickly pear), cactus pear, collard greens, dandelion greens, endive, escarole, mustard greens, squash (acorn, butternut, scallop, spaghetti, summer), and turnip greens.

Feed occasionally: alfalfa sprouts, apples, fresh apricots, beans (garbanzo, green, kidney, lima, pinto), bell peppers, blackberries, blueberries, red cabbage, cantaloupe, raw carrots, celery, cherries (no pit), cilantro, clover, fresh cranberries, cucumbers, grape leaves, grapefruit, grapes, honeydew melon, nectarines, oranges, pea sprouts, peaches, pears, pineapple, prunes, raw pumpkin, radish, raisins, kelp, strawberries, watermelon, wheat grass, and raw yams.

Feed rarely: banana, soybeans, beet greens, beets, broccoli, cauliflower, corn, whole hard-boiled egg, kiwi, red leaf or romaine lettuce, canned pitted olives, parsley, peas, pomegranate, potato, raspberries, rice, rutabaga, Brussels sprouts, starfruit, Swiss chard, and tomato.

Never feed: meat, insects, bran, bread, Cheerios, chives, eggplant, garlic, iceberg or loose leaf lettuce, mushrooms, onion, pasta, spinach, or yogurt.

Supplementation:

  • Calcium carbonate (without D3) — e.g., Zoo Med ReptiCal — sprinkled on food 2–3 times weekly
  • Multivitamin containing true vitamin A — e.g., Zoo Med Reptivite — once weekly. If housed indoors, use Reptivite with D3

Brumation & Estivation

In the wild, Russian tortoises naturally brumate during the colder months. If you plan to brumate your tortoise, a veterinary examination beforehand is recommended to ensure your pet is healthy enough for the process.

Russian tortoises also undergo a period of rest during the hottest, driest days of summer known as estivation. If the enclosure has plenty of shade and is regularly watered, the tortoise may remain active. Otherwise, it may retreat to its burrow and only be active in the early morning or at night.

Wellness & Preventive Care

We recommend an annual fecal exam and wellness checkup. Seek veterinary care promptly if your tortoise is lethargic, not eating or growing well, has nasal discharge or difficulty breathing, has puffy or discharging eyes, a soft shell, mobility issues, or has been attacked by another animal.
