Hermann's Tortoise

About the species

The Hermann's tortoise (Testudo hermanni) comes from the Mediterranean regions of Southern Europe, where it lives in dry grasslands, scrubland and woodland edges with warm summers and cooler winters. It's a land tortoise that's easy to mistake for a low-maintenance terrarium pet, but its real distinguishing feature is that long-term care goes well beyond a "small box on a shelf" – an adult needs outdoor space above almost everything else, and its expected lifespan is measured in decades, not years.

Housing: a garden, not a tank

A hatchling can spend some time in an indoor "tortoise table" setup of at least 100 × 50 cm, but that's mainly a stopgap arrangement. An adult Hermann's tortoise needs a secure, enclosed outdoor space of at least a few square meters with access to both sun and shade; when outdoor space simply isn't available, the RSPCA recommends at least 180 × 120 cm of indoor space, considerably more than most people picture when they bring home a small hatchling. The fencing needs to run deep enough underground and be tall enough, since Hermann's tortoises are surprisingly capable diggers and climbers that can escape through a garden edge that looks perfectly secure.

Temperature gradient and basking

The basking spot should reach 32–35°C, while daytime shaded temperatures can sit between 24 and 29°C. At night, a healthy adult outside the hibernation period can tolerate a drop to roughly 18°C without harm, a considerably more forgiving range than many tropical terrarium species allow.

UVB lighting

UVB lighting is essential for a Hermann's tortoise, since the species spends a great deal of time in direct sunlight in the wild and uses UVB exposure for vitamin D3 synthesis and calcium metabolism. For indoor housing – hatchlings, winter months – a quality UVB tube is therefore mandatory equipment, not an optional extra.

Humidity and diet

Humidity should sit between 40 and 60%, running somewhat higher for hatchlings, since insufficient humidity during early growth raises the risk of pyramided shell growth. The Hermann's tortoise is herbivorous and needs a high-fiber, low-protein diet – mainly grasses, weeds and leafy greens – not large amounts of fruit or dog/cat food, as was sometimes wrongly recommended in the past. Dandelion and plantain are popular, inexpensive greens, and the diet is worth supplementing with cuttlebone or a similar calcium source the tortoise can gnaw on as needed.

Winter hibernation

In the wild, Hermann's tortoises overwinter in a dormant state, and the same holds for many healthy, sufficiently heavy captive individuals. Hibernation needs to be supervised, held at a consistently low temperature around 5°C, with regular weighing throughout, since incorrectly managed hibernation is one of the leading causes of death in this species – it isn't a process to improvise. A vet check before hibernation is advisable, and the animal needs enough time beforehand to empty its digestive tract, since undigested food left inside the body during hibernation can cause complications.

Company of its own kind

A Hermann's tortoise doesn't need company from other tortoises for its wellbeing, but with enough space, group housing is still possible. Watch the sex ratio carefully, since males can be aggressive toward each other and toward females, especially during the mating season, so a group without an excess of males works considerably better.

Handling

A Hermann's tortoise should be picked up rarely and carefully, always supported with both hands under the shell, since even a short fall can seriously injure the shell or internal organs. Sudden lifting often triggers bladder voiding, which is a normal defensive response rather than a sign of illness.

Legal protection

The species is listed in Annex A of the EU Wildlife Trade Regulation and Appendix II of CITES, which means proof of legal origin – such as a captive-breeding certificate – is normally required. Check the specific requirements with the relevant authority before acquiring one.

Lifespan and the decision to get one

A Hermann's tortoise can live 50 years or more, placing it among the longest-lived pets kept by anyone – the owner is effectively taking on a commitment that can outlast their own period of active caregiving. Day-to-day care (diet, temperature, UVB) isn't demanding on its own, but combined with its longevity and the real risk built into winter hibernation, the species suits a beginner only conditionally – that is, someone genuinely aware of the long-term commitment involved. Since this is a long-lived, legally protected species, it's also worth considering adopting an individual that a previous owner rehomed precisely because of that same long-term commitment.
