Species Profile & Temperament

Housing & Enclosure

Enclosure Type & Size

• Type: Terrestrial / Extreme Burrowers.
• Minimum for Adults: A large, wide enclosure or "Tortoise Table" (ask our staff to help you choose a size). Despite being small, they are incredibly active and need a lot of floor space to roam.
• Outdoor Pens: They thrive outdoors in the summer. However, they are master escape artists. They will dig under fences and climb over low walls. Any outdoor pen must have walls sunk well into the ground.

Substrate

• Recommended: A deep 50/50 mix of organic topsoil and coconut fiber (Eco Earth).
• Depth: Deep enough to burrow into. Ask our staff for the depth we use. They are burrowing animals and need deep dirt to dig into to regulate their temperature and feel secure.
• Avoid: Sand (impaction risk), pine/cedar (toxic), and rabbit pellets (molds instantly when wet).

Décor & Enrichment

• Hides: Provide a large half-log or cork flat for them to hide under.
• Water Dish: Provide a shallow water dish large enough for them to stand in, but shallow enough that the water doesn't go past their chin (they can drown easily).

Heating & Lighting

Temperature Requirements

Give them a warm basking spot at one end and a cooler end at the other. A little cooler at night is fine. Ask our staff for the range we keep ours at, and check both ends with a thermometer.

• Heating: A halogen basking bulb is ideal for daytime heat. They can tolerate significant temperature drops at night, so supplemental night heating is usually unnecessary unless your house gets very cold.

Lighting & UVB (CRITICAL)

• UVB is 100% Mandatory. Without strong UVB lighting, your tortoise cannot synthesize Vitamin D3, meaning it cannot absorb calcium. This leads to Metabolic Bone Disease (MBD), which causes deformed, soft shells and eventual death.
• Recommended: A T5 high-output linear UVB bulb (like the Arcadia 12% Desert or Zoo Med ReptiSun 10.0) spanning 1/2 to 2/3 the length of the enclosure. Write the install date on the bulb and replace it when its label says.

Humidity & Water

• Target Range: Fairly dry (Arid). Ask our staff for the range we keep ours at.
• The Humid Hide: While the overall enclosure should be dry, they burrow in the wild to find moisture. You must provide a "humid hide"—a hide box filled with damp sphagnum moss. This prevents their shell from growing abnormally (pyramiding).
• Soaking: Soak your tortoise in shallow, lukewarm water regularly, babies more often than adults. Ask our staff how long and how often. This ensures they stay hydrated, as many tortoises are bad at drinking from bowls.

Diet & Nutrition

Russian Tortoises are strict herbivores. Never feed them animal protein (insects, dog food) or fruit. Fruit causes massive digestive upset and parasite blooms in their gut.

The "Weed" Diet

In the wild, they eat dry grasses and broadleaf weeds. Their diet should be high in fiber and low in protein/sugar.

• Staples (Feed Daily): Dandelion greens, endive, escarole, mustard greens, turnip greens, and radicchio.
• Treats (Sparingly): Hibiscus flowers, rose petals, spineless Opuntia cactus pads.
• Avoid: Spinach (binds calcium), iceberg lettuce (no nutrition), fruit (too much sugar), and pellets with artificial dyes.

Supplements

• Calcium: Dust their greens with a calcium supplement and follow its label for how often. Ask our staff which calcium we recommend for a tortoise kept indoors.
• Multivitamin: Use a reptile multivitamin and follow its label for how often.

Health & Husbandry

Beak Trimming

Tortoises have a sharp, horny beak instead of teeth. In the wild, eating tough weeds and grazing on rocks wears their beak down. In captivity, eating soft grocery store greens can cause their beak to overgrow like a parrot's, preventing them from eating. Feed their greens on a piece of slate rock or terra cotta to help naturally file their beak.

Shell Pyramiding

If the scutes (scales) on a tortoise's shell grow upward into sharp pyramids rather than smooth domes, the tortoise has "pyramiding." This is a permanent deformity caused by a combination of low humidity, poor diet, and lack of UVB. Always provide a humid hide and proper calcium.

How We Keep Them at Critter Cabana & Gresham Pet Supply

• Beating Dry Oregon Furnace Air (and Summer Heat Spikes): Across the Willamette Valley and Portland Metro, running the house furnace all winter drops indoor humidity to 25–35%, which quickly causes stuck sheds and dehydration in screen-top tanks. To hold steady humidity for Russian Tortoise, our crew uses a deep substrate bed (or our store-shelf 10-Part Bioactive Mix of ReptiSoil, Coco Fiber, Orchiata Bark, Sphagnum Moss, and Leaf Litter), a dedicated humid hide packed with damp sphagnum moss, and partial screen cover when needed.
• Thermostat & Linear UVB Standard: Every heating element in our Newberg and Gresham reptile rooms runs on a thermostat probe, with a warm side and a cool retreat set to the range we keep ours at, paired with linear UVB lighting on a 12-hour day/night timer. In summer, if an upstairs room climbs above 82°F, a dimming thermostat automatically backs down the basking lamp so the cool side never overheats.

Common Questions (FAQ)

What size tank does an adult Russian Tortoise actually need?

An adult Russian Tortoise needs a large, wide tortoise table or enclosure with room to roam, a warm basking side and a cooler side. Ask our staff to help you choose a size and for the temperature range we keep ours at.

How do I keep Russian Tortoise humidity up during dry Oregon winters?

Oregon winter furnace heat dries out thin bedding fast. Use a deep moisture-retaining substrate mix (such as Zoo Med ReptiSoil blended with coco fiber, Orchiata bark, and sphagnum moss), provide an enclosed humid hide, and cover 50–70% of an open screen top with HVAC foil tape or a PVC panel if ambient humidity drops too low.
