Hermann's Tortoise
Testudo hermanni
The friendly, manageable Mediterranean tortoise — a great first tortoise like the Russian, with the same decades-long commitment.
Difficulty: Beginner–IntermediatePrintable care sheet →
Hermann's tortoises are the classic small Mediterranean tortoise — busy, bright-eyed grazers with bold yellow-and-black shells and (often) a little horny nail on the tail-tip. They're one of the friendliest, most manageable first tortoises, closely comparable to the Russian in care. Like all Testudo tortoises they are temperate animals that hibernate through winter, they graze on weeds and greens (not grocery veg), and they need far more floor space than people expect — an outdoor grazing pen is the dream. Get the space, diet, and hibernation question sorted and they're hardy, charming, multi-decade companions.

Care at a glance
| Adult size | Typically 6–8 in (15–20 cm); the larger Eastern subspecies can reach ~11 in, and males are smaller than females |
|---|---|
| Lifespan | 50–90 years — a lifelong, potentially multi-generational commitment |
| Enclosure | Floor space matters far more than height. Indoor minimum is about 22 sq ft of floor for one — an open-topped table or large enclosure, never a small terrarium. A predator-proof OUTDOOR grazing pen is ideal whenever the weather allows, with walls ~24 in above ground and sunk ≥12 in below to stop climbing and digging escapes. They’re happiest kept singly; add floor space per extra tortoise. |
| Basking / warm zone | Basking area 95–100°F (35–38°C) from an overhead halogen flood on a thermostat (some vets suggest a slightly lower 90–95°F). |
| Cool side | Cool/shaded zone 75–85°F (24–29°C), giving a full gradient. |
| Night | Night below ~72°F (22°C); a natural drop is fine and healthy. |
| UVB & lighting | Strong UVB is essential for a diurnal grazer: a T5 HO 12% bulb (Arcadia Desert 12% or Zoo Med ReptiSun 10.0) giving UVI 3.0–4.0 in the basking area (Ferguson Zone 3), mounted at the maker’s recommended height (~17–18 in above the shell), plus a bright ~6500K LED for daylight. Run ~14 hours in summer, 10 in winter. Replace the UVB bulb every 12 months. |
| Humidity | Adults 40–60%; hatchlings higher at 60–80%, with daily misting or a shallow soak — too-dry keeping is a main cause of a bumpy, “pyramided” shell, so don’t keep a young one bone-dry. A humid hide helps. |
| Substrate | A deep, burrowable roughly 50/50 topsoil-and-play-sand mix, no less than 6 in deep, that holds a little moisture and lets them dig. They are avid diggers and burrowers. Spot-clean daily; refresh every few months. |
| Diet | A grazing HERBIVORE that needs a high-fibre, LOW-protein, LOW-sugar diet: mostly leafy greens, grasses, and edible “weeds” (dandelion, plantain, clover) plus flowers as treats. NOT the vegetables and fruit from the produce aisle — those are too rich. Fruit and any animal protein are, at most, rare mistakes to avoid. |
| Supplements | Provide a cuttlebone in the enclosure (calcium + it keeps the beak trimmed), and lightly dust food with calcium; a light multivitamin on a rotation. |
What it's like to live with a Hermann's Tortoise
A Hermann's tortoise is a long-haul companion with more personality than people expect — a grazer and digger, happiest with floor space to roam, weeds to browse, and soil to burrow into. This is not a handling pet; a tortoise would rather be pottering than picked up, but a settled one is curious, food-motivated, and will trundle over to investigate you. The daily rhythm is calm and grounding: fresh greens in the morning, a good basking session, some digging and exploring, then a dig-down for the night. The single biggest commitment is the decades — and the yearly winter hibernation question that comes with a temperate tortoise.
Your first month together
The settling-in period, in order — so you know what's normal and when not to worry.
- Give it space and time to explore and settle — a new tortoise will dig, hide, and pace the edges as it maps its territory. Let it.
- Offer a wide variety of leafy weeds and greens daily; a settling tortoise may be cautious about food at first, then tuck in once it feels at home.
- Provide a warm basking spot and proper UVB from day one, and soak a young tortoise in shallow warm water a few times a week to keep it hydrated and its shell growing smoothly.
- Watch that it is eating, basking, and passing droppings within the first week or two — those are your core "settling in well" signs.
- Handle minimally and low to the ground; tortoises feel unsafe when lifted, and a dropped tortoise can be badly hurt.
Through the year, and as they grow
Hermann's tortoises have a strong seasonal rhythm: healthy adults naturally hibernate through winter, slowing right down and going off food. In a temperate climate they’re typically kept outdoors from around April to October and brought into a cooler indoor space (or a controlled hibernation) over winter. Crucially, hibernation is ONLY ever for a tortoise a vet has confirmed is healthy and a good weight — a sick or underweight tortoise must be kept warm and awake instead. Appetite and activity swing with the seasons.
The pet store gets these wrong
Common myths, kindly corrected — no shame for having believed them.
- A tortoise is happy in a small terrarium or tortoise table — no; it needs a lot of floor space, ideally an outdoor pen.
- Feed it grocery lettuce, veg, and fruit — no; those are too rich. Feed weeds, greens, and grasses.
- Tortoises are easy, low-commitment starter pets — hardy, yes, but this is a 50–90-year, space-hungry animal.
- Keep it bone-dry — no; too-dry keeping causes a pyramided shell, especially in hatchlings. It needs moderate humidity and a humid hide.
- “Dog/cat food or high protein helps it grow” — dangerous; excess protein causes shell pyramiding and kidney/gout problems.
Before you buy
- Real floor space — about 22 sq ft indoors minimum, ideally a predator-proof outdoor grazing pen.
- A 50–90-year commitment (genuinely plan who inherits it).
- A weed-and-green grazing diet, not grocery veg/fruit; strong UVB; a cuttlebone.
- A decision about winter hibernation — and an exotics/reptile vet who sees tortoises.
See a reptile vet if…
We can't diagnose from afar — but these are the signs to stop watching and get a professional:
- A soft, lumpy, or badly “pyramided” shell, or a rubbery beak (signs pointing to metabolic bone disease / husbandry problems).
- A runny or bubbling nose, or open-mouth breathing (possible respiratory infection — common in tortoises).
- Not eating with straining, or a female restless and straining (possible impaction or egg-binding).
- An overgrown beak or nails, or swollen/puffy eyes.
- Lethargy or weight loss going into or coming out of hibernation — see a vet, don’t “sleep it off”.
Never
- Never feed dog/cat food or a high-protein diet — it causes shell pyramiding and kidney/gout disease.
- Never hibernate a sick, underweight, or unwell tortoise.
- Never keep it in a small terrarium or bare tortoise table as its only space.
- Never house two males together.
- Never let it get cold without proper hibernation prep and a vet check first.
Common hermann's tortoise questions
How hard are Hermann's Tortoises to keep — are they good for beginners?
Beginner–Intermediate. One of the best first tortoises alongside the Russian — hardy, friendly, and manageable in size. But "beginner" still means real floor space (ideally an outdoor pen), a specific weed-and-green diet, and a decades-long, hibernating animal that can outlive you. The commitment, not the daily care, is the hard part.
What do Hermann's Tortoises eat?
A grazing HERBIVORE that needs a high-fibre, LOW-protein, LOW-sugar diet: mostly leafy greens, grasses, and edible “weeds” (dandelion, plantain, clover) plus flowers as treats. NOT the vegetables and fruit from the produce aisle — those are too rich. Fruit and any animal protein are, at most, rare mistakes to avoid.
How big an enclosure do Hermann's Tortoises need?
Floor space matters far more than height. Indoor minimum is about 22 sq ft of floor for one — an open-topped table or large enclosure, never a small terrarium. A predator-proof OUTDOOR grazing pen is ideal whenever the weather allows, with walls ~24 in above ground and sunk ≥12 in below to stop climbing and digging escapes.
