Overview

Russian tortoises are small, hardy tortoises from Central Asia, popular for their personable nature, manageable size (8-10 inches), and active behavior. They are herbivores that thrive in arid environments and can live many decades with proper care. Their scientific name Agrionemys horsfieldii honors Thomas Horsfield.

Enclosure Sizes by Life Stage

Life StageMinimum Enclosure Size
Hatchling0–3 months20-gallon long (30x12x12") or 2x4 ft tortoise table
Juvenile3–12 months4x4 ft tortoise table or indoor pen

Housing

Enclosure type
Large indoor tortoise table or outdoor pen; needs more roaming space than most realize
Substrate
Soil/sand mix, coconut coir, or topsoil (4-6 inches deep). Must be dig-able. Avoid wood shavings. Outdoor tortoises will dig extensive burrows.
Hides
Hide large enough to fully conceal the tortoise; burrow access if possible
Notes
Minimum 4x8 feet indoor enclosure or outdoor pen in suitable climates. Tortoises need more space than most realize. Provide hide, basking area, and room to roam. Outdoor housing is ideal in warm, dry climates.

Feeding

Staple food
Variety of grasses, weeds, dark leafy greens (dandelion, plantain, endive, spring mix)
Variety
Mazuri tortoise diet as supplement; NO fruit, limited vegetables
Frequency
Feed daily, as much as they will eat in 30 minutes. Remove uneaten food. Provide grazing opportunities if possible.
Supplements
Dust food with calcium (without D3) 3x per week, calcium with D3 1x per week. They can make D3 from UVB.
Notes
STRICT HERBIVORE: Feed variety of grasses, weeds, dark leafy greens (dandelion, plantain, endive, spring mix). NO fruit, limited vegetables. Fiber-rich diet essential. Mazuri tortoise diet can supplement.

Water & Hydration

Water bowl
Large shallow water dish; change daily; soak hatchlings 3x per week
Notes
Provide large shallow water dish for drinking and soaking. Change daily. Soak hatchlings 3x per week for 15-20 minutes to ensure hydration.

Handling

Disposition
Personable and active; tolerates handling but it is stressful; keep sessions brief
Recommendations
Generally tolerate handling but it's stressful. Keep handling minimal. Support shell completely. They may urinate when picked up (defense mechanism) - this is normal but causes dehydration.

Common Health Issues

Respiratory infections, shell rot, pyramiding (from incorrect diet/humidity), bladder stones, and vitamin A deficiency.

Special Notes

Russian tortoises can live 40-50+ years. They brumate (hibernate) naturally in winter, even in captivity. This is normal but requires preparation. Females are larger than males. They are excellent diggers and will burrow extensively. Need annual vet checkups. Males can be aggressive toward each other and may harass females excessively. Best housed individually or one male with multiple females in very large space. Outdoor housing is ideal when possible - natural sunlight is invaluable.
