Russian tortoises do really well when the basics are dialed in.
🐢 Russian Tortoise (Testudo horsfieldii) Care Sheet
For Adult Tortoises | Beginner-Friendly | Vet-Informed
🧭 Overview
- Lifespan: 40–60+ years
- Adult size: 5–10 inches
- Personality: Active, curious, burrowers
- Key principle: Dry species that needs high fiber, low protein, high UVB, and proper heat gradients
🥬 Diet & Eating
✅ What to Feed (80–90% of diet)
- Dark leafy greens:
- Dandelion greens
- Collard greens
- Mustard greens
- Turnip greens
- Weeds (excellent if pesticide-free):
- Plantain
- Clover
- Sow thistle
➕ Occasional (10–20%)
- Romaine lettuce
- Endive, escarole
- Hibiscus leaves/flowers
❌ Avoid
- Fruit (too much sugar → gut dysbiosis)
- Iceberg lettuce (no nutrition)
- High-protein foods (dog/cat food, beans)
- Spinach (binds calcium)
🧂 Supplements
- Calcium powder (no phosphorus): 3–5x/week
- Vitamin D3: 1–2x/week (if UVB exposure is uncertain)
🕒 Feeding Routine
- Feed daily
- Offer as much as they’ll eat in ~20–30 minutes
💧 Drinking & Hydration
Key Point:
Russian tortoises are from dry regions—but still need regular hydration
💦 Water Access
- Shallow water dish at all times
🛁 Soaking (VERY important)
- 2–3 times per week
- Lukewarm water (shell height)
- 15–20 minutes
➡️ Supports:
- Hydration
- Kidney health
- Prevents urate stones
🛏️ Sleeping & Behavior
- Diurnal (awake during the day)
- Sleep at night in a burrow or hide
- May dig and bury themselves—this is normal
💤 Signs of healthy rest:
- Active during the day
- Settles down at night
- Regular basking
🌡️ Temperature Requirements
🔥 Basking Area
- 95–100°F (35–38°C)
🌤️ Ambient Temperature
- 75–85°F (24–29°C)
🌙 Night Temperature
- Can drop to 65–70°F (18–21°C) safely
🌡️ Tools
- Use digital thermometers (not stick-ons)
- Measure both basking and cool zones
☀️ UVB Lighting (CRITICAL)
- Use high-quality UVB bulb (10.0 / desert type)
- 10–12 hours/day
- Replace bulb every 6–12 months
➡️ Without UVB → metabolic bone disease (MBD)
🏡 Enclosure Requirements
📏 Size
- Minimum: 4 ft x 2 ft (larger is better)
🧱 Substrate
- Safe options:
- Topsoil (no chemicals)
- Coconut coir
- Depth: 3–6 inches (for burrowing)
🏠 Must Include
- Hide box (cool side)
- Basking area (warm side)
- Water dish
- Flat rock for feeding
🌬️ Humidity
- Low to moderate (30–50%)
- Avoid overly damp environments
🏞️ Ideal Condition Goals
- Bright, alert, active
- Clear eyes, no discharge
- Smooth, firm shell (no soft spots)
- Strong appetite
- Regular urates (white, toothpaste-like—not gritty)
❄️ Wintertime Care
⚠️ Important:
Russian tortoises may attempt brumation (hibernation)
For Beginners:
👉 DO NOT allow brumation unless properly prepared
Instead:
- Maintain normal heat/light year-round
- Watch for:
- Decreased appetite
- Lethargy
➡️ These may indicate illness—not just seasonal behavior
🚨 Signs of Disease
🫁 Respiratory Infection
- Nasal discharge
- Wheezing or open-mouth breathing
- Lethargy
🦴 Metabolic Bone Disease (MBD)
- Soft shell
- Tremors
- Weakness
- Deformed limbs
💩 GI / Parasites
- Diarrhea
- Weight loss
- Poor appetite
💧 Dehydration / Kidney Issues
- Thick, gritty urates
- Lethargy
- Sunken eyes
🐢 Shell Problems
- Rot (soft, smelly areas)
- Pyramiding (chronic husbandry issue)
🛡️ Disease Prevention
🧪 Parasite Control
- Fecal exam:
- At acquisition
- Then 1–2x/year
- Deworm only if indicated (not routine blind treatment)
🥗 Nutrition
- High fiber, low protein
- Calcium supplementation
- Avoid fruit overload
☀️ Lighting & Heat
- Proper UVB + basking temps prevent most disease
💧 Hydration
- Regular soaking is critical
🧼 Hygiene
- Clean enclosure weekly
- Fresh water daily
🧠 Quick “Golden Rules”
If someone remembers just this, they’ll avoid 90% of problems:
- No fruit, mostly weeds/greens
- Strong UVB + hot basking spot
- Soak regularly—even desert tortoises
- Big enclosure with room to dig
- Don’t let them “hibernate” casually
