📋 At a glance

🏠 Enclosure

• Outdoor enclosure preferred for suitable weather; indoor tortoise table or large pen for juveniles/cold season
• Adult space should be measured in square meters, not small terrariums
• Substrate: soil/sand/clay mix that allows walking, digging, and moisture gradient
• Avoid glass tanks for adults, slippery floors, cedar/pine, and cat litter

🪨 Enclosure furniture

• Basking area, cool retreat, shaded hides, edible plants, and humid hide for juveniles
• Flat stones, roots, and terrain variation without sharp edges
• Shallow water dish easy to enter and exit

💡 Lighting

• UVB essential indoors
• Best: T5 HO UVB plus separate basking heat or a measured mercury vapor system
• Outdoor direct sun is excellent; glass/plastic blocks UVB
• Photoperiod: 10-12 h with seasonal adjustment; no night light

🌡️ Temperature

• Basking spot: 32-35 °C

• Warm zone: 26-30 °C

• Cool zone: 20-24 °C

• Night: 16-20 °C

• Clear gradient required; the animal must be able to move between warm, cool, and hidden zones

• Measure basking surfaces with an infrared thermometer and ambient zones with digital probes

• Avoid heat rocks and unguarded heat sources

💧 Humidity & water

• Provide a dry surface plus access to slightly moist retreats
• Fresh shallow water always available
• Juveniles benefit from regular hydration and humid hides
• Avoid both swampy substrate and completely bone-dry rearing

🥬 Diet

Feed regularly:

• Safe weeds, grasses, leaves, flowers, and high-fiber greens

In moderation:

• Commercial greens, flowers, and seasonal extras

Avoid:

• Fruit-heavy diets, animal protein, dog/cat food, bread, dairy

Supplements:

• Cuttlefish bone or calcium; UVB is still required

💤 Brumation

• Hibernation/brumation is species-specific and only for healthy animals with correct preparation
• Do not hibernate sick, underweight, newly acquired, or very young animals
• Check weight, hydration, parasite risk, and gut emptying before cooling
• Consult a reptile vet or experienced keeper before the first attempt

🩺 Health — warning signs

• Soft shell → UVB/calcium issue
• Pyramiding or rapid shell distortion → diet/humidity/growth problem
• Nasal discharge or wheezing → respiratory disease
• Swollen eyes → infection, vitamin, or hygiene issue
• Lethargy outside cool season → illness or temperature problem

Consult a reptile- or exotic-animal veterinarian for severe weakness, injury, breathing signs, swelling, or prolonged refusal to eat.
