Hermann's Tortoise Care Guide: Housing, Diet, and Lifespan
Hermann's tortoises are gentle Mediterranean tortoises that can live for decades with the right care. This guide covers their spacious housing, basking heat and UVB, a high-fibre weed-based diet, and what their long lifespan really means, so you can set up a healthy home and plan for a lasting commitment.
Quick answer
Hermann's tortoises need a large, well-ventilated enclosure of at least 120 x 60 cm, a basking spot around 32-35°C, strong UVB, and a high-fibre diet of leafy weeds and greens. They are Mediterranean grazers that can live 50 years or more, so they are a genuine lifetime pet. Get their space, heat, UVB, and diet right and they are hardy and rewarding.

Meet the Hermann's tortoise
Hermann's tortoises come from the warm, dry Mediterranean and are among the most popular pet tortoises thanks to their manageable size and gentle nature. Adults typically reach 15-20 cm, with a distinctive yellow-and-black shell. Their key feature for owners is longevity: with good care they routinely live for decades, often outliving other family pets, so buying one is a long-term decision.
Housing and space
Despite their modest size, Hermann's tortoises are active grazers that need room to roam. Provide an open-topped tortoise table or large enclosure of at least 120 x 60 cm for one adult, and more where possible. Open tops give the ventilation these dry-climate animals need, which matters especially in a humid or typhoon-prone climate where stagnant damp air raises the risk of respiratory infection.
A spacious, well-ventilated tortoise table with a clear warm basking end suits a Hermann's tortoise best.
Use a firm, diggable substrate such as a topsoil-and-sand mix, and add a low hide and a shallow water dish for soaking and drinking. Many keepers give their tortoise safe, supervised outdoor time on warm days, which provides natural sunlight and grazing.
Heat, light, and UVB
Create a temperature gradient with a basking area of 32-35°C at one end and a cooler end around 20-25°C. Use a basking lamp on a thermostat and verify temperatures with a thermometer. Room temperature at night is usually acceptable if it does not drop too low.
UVB is essential for healthy shell and bone growth. Fit a UVB source over the enclosure and replace it every 6-12 months, since output declines before the bulb visibly fails. Real sunlight is excellent when it is warm and safe, but never leave a tortoise in a glass container in direct sun, where temperatures can climb dangerously fast.
Diet and feeding
Hermann's tortoises are herbivores adapted to fibrous Mediterranean plants. Feed a varied diet of leafy weeds and greens such as dandelion, clover, plantain, and sow thistle, with some vegetables and grass hay for fibre. Dust food with calcium regularly and keep a cuttlebone available for self-regulated calcium.
Hermann's tortoises thrive on varied fibrous weeds and greens, with a cuttlebone for extra calcium.
Avoid fruit, which is too sugary, and never feed high-protein foods like dog food, cat food, or meat, which can cause shell deformities and kidney damage over time. Learn your local toxic plants before foraging outdoors.
Lifespan and hibernation
A Hermann's tortoise is a decades-long commitment, and many owners underestimate this. Plan for who will care for it across your life changes. Hermann's tortoises hibernate naturally, but hibernation is only safe for a healthy, correctly weighted animal under controlled conditions. Never hibernate a sick or underweight tortoise, and always plan hibernation with a reptile vet.
Quick FAQs
How long do Hermann's tortoises live? With good care, commonly 50 years or more, so they are a genuine lifetime and even multi-generational pet.
Do they need UVB if kept indoors? Yes. Indoor tortoises need a proper UVB source to metabolise calcium and avoid shell and bone disease.
Can I feed lettuce and fruit? Feed varied weeds and greens instead of relying on lettuce, and avoid fruit, which is too sugary for their digestive system.
Is hibernation necessary? Not in captivity. It can be done safely for healthy tortoises, but it is optional, and a vet should guide any hibernation plan.
