Greek Tortoise Care Guide

Testudo graeca

Greek tortoises are a small to medium-sized tortoise adapted to warm, arid climates. They include a variety of subspecies throughout their geographic range, including Turkey, the Middle East, Sardinia, North Africa, and southern Spain. Males tend to be smaller than females. This species can live 50+ years as pets.

Enclosure

Outdoor enclosures are preferred for most tortoises, especially in warm, arid climates. Use caution in wet or humid areas — this species is prone to respiratory disease and shell infections when kept too wet. Outdoor enclosures for adults should be at least 4 ft × 6 ft, with opaque, smooth sides to prevent climbing and escape attempts, and predator-proofed. Outdoors, provide access to both direct sunlight and shade, along with artificial burrows for cool, humid retreat on hot days and insulation during winter.

For indoor housing, a “tortoise table” setup or large storage tub is recommended over glass aquariums — these allow better ventilation and prevent the tortoise from repeatedly attempting to walk through clear glass.

Provide hides at both the warm and cool ends — cork rounds, hollow logs, caves, or overturned planter pots all work well. A humid hide filled with damp sphagnum moss is recommended and especially important for hatchlings and juveniles to promote normal shell growth and development. Live plants inside the enclosure should be edible and non-toxic.

Substrate

Avoid gravel and sand — these may be ingested and cause impactions. For indoor enclosures, cypress mulch and organic topsoil are good choices. Always feed on a flat flagstone, tile, or similar surface rather than directly on substrate to prevent accidental ingestion.

Temperature

The preferred temperature zone is 85–95°F, with a nighttime drop to 65–70°F well tolerated by healthy individuals.

Indoors:

  • Basking area: 95°F
  • Cool end: 70–75°F

Provide heat with basking bulbs, ceramic heat emitters, or radiant heat panels. Hot rocks should be avoided. Monitor temperatures with a digital or infrared thermometer; a thermostat is recommended to ensure temperatures remain appropriate.

Outdoors, tortoises will retreat into cooler burrows during hot weather. When temperatures drop below 50–60°F, brumation will begin.

Lighting

Greek tortoises require UVB lighting to process calcium properly. For indoor tortoises, use high-output fluorescent or mercury vapor bulbs rated for desert reptiles — such as the ReptiSun 10.0 or Arcadia 12%. Place UVB lighting no more than 12–18 inches from the basking site (follow manufacturer guidelines; monitoring UV output with a Solarmeter is recommended). Connect to a timer — approximately 14 hours of light in summer and 10 hours in winter. Replace bulbs every 6–12 months — they stop producing UVB long before they stop producing visible light. Outdoor tortoises receive all the UVB they need from the sun.

Humidity & Water

Maintain 30–60% humidity for most subspecies, measured with a digital hygrometer. Hand misting can help maintain appropriate levels.

Soak tortoises in shallow warm water for 15 minutes 2–3 times weekly to encourage drinking, urination, and defecation. A large, flat, shallow water bowl can be provided indoors and should be changed and cleaned daily. Do not leave standing water in outdoor enclosures for more than a day or two — stagnant water can harbor protozoan parasites that may cause illness.

Diet

Greek tortoises are herbivores. Their natural diet consists of edible weeds, grasses, and thistles. Tortoises can also be offered Mazuri LS pellets softened in water every 2–3 days.

Feed daily (staples): shrubs, weeds, forbs, alfalfa, grass hay (timothy), cactus pad/leaf (prickly pear), cactus pear, collard greens, dandelion greens, endive, escarole, mustard greens, squash (acorn, butternut, hubbard, scallop, spaghetti, summer), and turnip greens.

Feed occasionally: alfalfa sprouts, apples, fresh apricots, beans (garbanzo, green, kidney, lima, pinto), bell peppers, blackberries, blueberries, red cabbage, cantaloupe, raw carrots, celery, cherries (no pit), cilantro, clover, fresh cranberries, cucumbers, grape leaves, grapefruit, grapes, honeydew melon, nectarines, oranges, pea sprouts, peaches, pears, pineapple, prunes, raw pumpkin, radish, raisins, kelp, strawberries, watermelon, wheat grass, and raw yams.

Feed rarely: banana, soybeans, beet greens, beets, broccoli, cauliflower, corn, whole hard-boiled egg, kiwi, red leaf or romaine lettuce, canned pitted olives, parsley, peas, pomegranate, potato, raspberries, rice, rutabaga, Brussels sprouts, starfruit, Swiss chard, spinach, and tomato.

Never feed: meat, insects, bran, bread, Cheerios, chives, eggplant, garlic, iceberg lettuce, mushrooms, onion, pasta, or yogurt.

Supplementation:

  • Calcium carbonate (without D3) — e.g., Zoo Med ReptiCal — sprinkled on food 2–3 times weekly
  • Multivitamin — e.g., Zoo Med Reptivite — once weekly. If housed indoors, use Reptivite with D3

Brumation

In the wild, this species naturally undergoes brumation during the colder months. If you plan to brumate your tortoise, a veterinary examination beforehand is recommended to ensure your pet is healthy enough for the process.

Wellness & Preventive Care

We recommend an annual fecal exam and wellness checkup. Seek veterinary care promptly if your tortoise is lethargic, not eating or growing well, has nasal discharge or difficulty breathing, has puffy or discharging eyes, a soft shell, mobility issues, or has been attacked by another animal.
