Greek Tortoise
Testudo graeca
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 Greek 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: Greek Tortoises are closely related to Russian and Hermann’s Tortoises. They stay extremely small (usually maxing out at a mere 6-8 inches), making them one of the few tortoise species that can be reasonably housed indoors their entire life. They are highly interactive and will learn to rush over to you for food!
Housing & Enclosure
Enclosure Type & Size
- Type: Terrestrial.
- Minimum for Adults: A 4ft x 2ft enclosure or "Tortoise Table." Even though they are small, tortoises walk for miles a day in the wild. They need space to roam.
- Enclosure Walls: Avoid clear glass at the tortoise's eye level. Tortoises do not understand glass and will endlessly pace and scrape against it trying to walk "through" the invisible barrier. If using a glass tank, tape a background around the bottom 6 inches.
Substrate
- Recommended: A deep 50/50 mix of organic topsoil and coconut fiber (Eco Earth), or cypress mulch (Forest Floor).
- Depth: 3 to 4 inches deep. They love to dig and bury themselves to sleep.
- Avoid: Sand (impaction risk) and rabbit pellets.
Décor & Enrichment
- Hides: Provide at least two hides (a warm hide and a cool hide). Half-logs or cork flats work perfectly.
- Terrain: Add flat slate rocks to their enclosure. Walking on rocks naturally files down their sharp toenails so you don't have to clip them!
Heating & Lighting
Temperature Requirements
| Zone | Temperature |
|---|---|
| Basking Spot | 90–95°F (32–35°C) |
| Warm Ambient | 80–85°F (26–29°C) |
| Cool End | 75–80°F (24–26°C) |
| Nighttime Drop | 65–70°F (18–21°C) |
- Heating: Use an overhead incandescent or halogen basking bulb. Under-tank heat mats are practically useless for tortoises because their thick shell blocks the heat from reaching their organs.
Lighting & UVB (CRITICAL)
- UVB is 100% Mandatory. A tortoise without UVB will develop Metabolic Bone Disease (MBD). Their shell will grow soft, deformed, and eventually they will die.
- Recommended: A T5 high-output linear UVB bulb (like the Arcadia 12% Desert or Zoo Med ReptiSun 10.0) mounted overhead.
Humidity & Water
- Target Range: 40% to 60%.
- The Humid Hide: Tortoises need humidity while they sleep to prevent their shell from growing incorrectly (pyramiding). Provide a "humid hide" filled with slightly damp sphagnum moss on the warm end of the enclosure.
- Soaking: Soaking your tortoise in warm, shallow water (up to their chin) for 15-20 minutes once or twice a week is highly recommended. It encourages them to drink and to pass waste.
Diet & Nutrition
Greek Tortoises are strict herbivores. Do not feed animal protein.
The Leafy Green Diet
Their diet should consist of high-fiber, low-sugar greens and weeds.
- Staples (Feed Daily): Dandelion greens, endive, escarole, turnip greens, mustard greens, collard greens, and safe weeds like clover or plantain.
- Treats (Sparingly): Carrots, squash, hibiscus flowers.
- Fruit: Limit fruit to less than 5% of their diet (once a month). They lack the gut bacteria to digest large amounts of sugar, which can cause severe diarrhea.
- Avoid: Spinach (binds calcium), iceberg lettuce, and dog/cat food.
Supplements
- Calcium: Dust their greens with pure calcium powder (without D3) 2-3 times a week.
- Multivitamin: Dust with a reptile multivitamin once a week to prevent Vitamin A deficiency.
- Cuttlebone: Leave a whole cuttlebone in their enclosure. They will chew on it when they crave calcium, which also helps file their beak!

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 Greek Tortoise actually need?
An adult Greek Tortoise needs at least 4x2x2 Enclosure / Tortoise Table so you can maintain a true thermal gradient from Basking 90-95°F / Cool 75-80°F on the warm/basking side down to comfortable room temperature on the cool side.
How do I keep Greek Tortoise humidity at 40-60% (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 Greek 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.
