Russian Tortoise
Testudo horsfieldii
1. Wide Walking Space, Strong UVB & Damp Digging Dirt
2. Two Great Ways to Set Up Your Habitat
Enclosure: Wide Glass Tank Setup vs. Summer Garden Pen
Tortoises are marathon walkers—and if they can see through clear glass, they'll bonk their nose trying to walk through it all day:
Option A: 40-Gal Breeder, 50-Gal Low-Boy, or 36"×18" Terrarium (Our Top Pick)
Wide floor space gives them room to roam! Just tape a 5-inch strip of dark paper around the outside bottom rim so they don't pace the glass.
Option B: Predator-Proof Outdoor Summer Pen
On sunny Oregon/Washington summer days (70–85°F), a wire-topped garden pen with pesticide-free dandelions and shade bushes is paradise!
Bedding: Why We Ditch Bone-Dry Pellets!
Old books used to recommend dry rabbit pellets or sand—we now know bone-dry bedding is what causes bumpy 'pyramided' shells!
Option A: Reptisoil + Forest Floor Cypress / ReptiBark (4–5" Deep)
Holds gentle moisture underneath for burrowing while giving firm traction; you can even seed Powder Orange/Blue or Giant Canyon Isopods + Springtails under the water dish!
Option B: Reptisoil + Eco Earth + Flat Slate Dinner Tile
Always serve greens on a rough flat piece of slate rock—scraping salad off stone files their beak down naturally so it never overgrows!
Sunbeam Lighting: Linear T5 HO UVB + Basking Flood Bulb
Tortoises need real, high-output UVB to build smooth, rock-hard shells:
Option A: Linear T5 HO 12% Desert UVB Bar + Basking Flood Bulb (Best!)
Covers a wide basking zone so their whole shell warms up under strong UV rays at once. Write the install date on the bulb base with a Sharpie and replace UVB every 6–12 months!
Option B: Overlapping Heat & UV Over a Flat Basking Stone
Hang your basking dome and T5 UVB hood side-by-side 10–12" above a flat rock on the warm end of the tank.
3. The 100% Weed & Leafy Green Menu
Greens, Pellets & Toppers We Love:
Dandelion, collard, mustard, turnip, endive
Soaked timothy-hay & herbal fiber pellets
Hibiscus, dandelion & rose petals (they go crazy for red/yellow!)
Leave a whole white cuttlebone in the tank 24/7
4. Four Keys to a Happy, Thriving Russian Tortoise
Warm Tub Soaks 2–3×/Week
Soak your tortoise in chin-deep warm water (85–88°F) in a dishpan for 15 minutes 2–3× a week. Don't panic when they pass toothpastey white 'urates' in the bath—that's normal tortoise pee!
Block Eye-Level Glass
If your tortoise is pacing one wall non-stop, tape a 5" strip of construction paper or vinyl around the bottom outside rim of the glass so they know where the wall stops.
Flip-Over Check
Tortoises love climbing everything! Sink their water dish flush with the dirt and keep steep log hides away from the direct center under the heat bulb so they can never flip upside-down under a hot lamp.
One Tortoise Per Table
Tortoises look peaceful, but two tortoises in one box will ram and bite each other's legs over territory. They are way happier living solo!

Why We Love Them: The Russian Tortoise is one of the absolute best pet tortoises in the world. Unlike a Sulcata that grows to 100+ pounds, Russian Tortoises stay small and manageable (usually under 8 inches). Despite their small size, they have massive personalities. They are fearless, active, and will quickly learn to recognize their owners and beg for food!
Housing & Enclosure
Enclosure Type & Size
- Type: Terrestrial / Extreme Burrowers.
- Minimum for Adults: A 4ft x 2ft enclosure or "Tortoise Table." 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 at least 12 inches into the ground.
Substrate
- Recommended: A deep 50/50 mix of organic topsoil and coconut fiber (Eco Earth).
- Depth: 4 to 6 inches deep. 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
| Zone | Temperature |
|---|---|
| Basking Spot | 90–95°F (32–35°C) |
| Warm Ambient | 80–85°F (26–29°C) |
| Cool End | 70–75°F (21–24°C) |
| Nighttime Drop | 65–70°F (18–21°C) |
- 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 drops below 60°F.
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. Replace the bulb every 12 months.
Humidity & Water
- Target Range: 30% to 50% (Arid).
- 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 baby tortoises in shallow, lukewarm water for 15 minutes twice a week. Soak adults once a week. 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 food lightly with pure calcium powder (without D3) 2-3 times a week.
- Multivitamin: Dust with a reptile multivitamin once every two weeks.
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

Common Questions (FAQ)
What size tank does an adult Russian Tortoise actually need?
An adult Russian Tortoise needs at least 4x2x2 Enclosure / Tortoise Table so you can maintain a true thermal gradient from Basking 90-95°F / Cool 70-75°F on the warm/basking side down to comfortable room temperature on the cool side.
How do I keep Russian Tortoise humidity at 30-50% (With a humid hide) during dry Oregon winters?
Oregon winter furnace heat dries out thin bedding fast. Use a 3–5 inch 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.
What is the best bioactive clean-up crew for a Russian Tortoise?
Pair Temperate White Springtails with a humidity-matched isopod species (such as Powder Blue/Orange for semi-arid setups or Dwarf White / Dairy Cow isopods for humid forest setups) in a 3–5 inch bioactive soil and leaf-litter bed. You can pick up our 1-Page or Tri-Fold Bioactive Substrate Recipe Guide and live cultures at Critter Cabana (Newberg) or Gresham Pet Supply.
