Hermann’s Tortoise Care Guide

(Testudo hermanni)

Quick Facts:

Appearance & Distinctive Features:

• Shell– Small to medium, high-domed shell that is sturdy and compact. Usually bright yellow or golden with bold black markings that form strong contrast patterns on each scute. Many have a clean, symmetrical “Mediterranean mosaic” look. Rear edge of the shell is slightly flared and the tail tip often has a small horny spur. The plastron typically shows two solid black stripes running lengthwise.
• Skin– Thick, dry, and scaly skin adapted for warm, dry climates. Colors range tan to gray or olive. Front legs are heavily armored with large protective scales for digging and pushing through brush. Unlike Greek tortoises, Hermann’s lack large thigh spurs.
• Size– Typically reach 5–8 inches in shell length. Some eastern/locality types may grow slightly larger. Adults usually weigh 1.5–4 lbs, making them small, active, and easy to manage compared to larger tortoise species.
• Sexual Dimorphism– Males are usually smaller with longer, thicker tails and concave plastrons. Females tend to be larger, rounder, and heavier with flatter plastrons and shorter tails.

Subspecies:

• Testudo hermanni hermanni (Western Hermann’s) – Typically smaller and more brightly colored with strong yellow and black contrast. Very crisp shell patterns and bold plastron stripes. Commonly 5–7 inches. Often considered the most colorful form and very popular in captivity.
• Testudo hermanni boettgeri (Eastern Hermann’s) – Usually larger and slightly darker or more olive in tone. Can reach 7–9 inches. Generally hardy and more tolerant of cooler weather, making them excellent outdoor tortoises in many parts of the U.S.
• Other local forms– Some regional variations and intergrades exist, especially in captive populations. Care requirements are nearly identical, though larger eastern types may need slightly more space and food.

Enclosure & Setup:

Indoor:

• Indoor Keeping– Works well for hatchlings and juveniles. Adults can also be housed indoors with enough space, but outdoor housing is preferred whenever weather allows since they benefit greatly from natural sunlight and fresh air.
• Size– For hatchlings I would go 3x2ft, juveniles about 4x2ft or 4x3ft, and adults at least 6x3ft or larger. Hermann’s stay small but are very active walkers and explorers, so extra floor space is always beneficial.
• Floor space– is most important. Tortoise tables or open-top enclosures work best for airflow and temperature control. Avoid small glass tanks.
• Substrate– I would use organic topsoil, coco coir, cypress mulch, or a soil/sand mix. Keep it slightly firm and dry on top with mild moisture underneath for digging. Avoid overly damp or muddy setups since this species prefers drier, Mediterranean-style conditions.
• Always provide a basking area with a proper heat gradient.
• Always have a shallow water dish and several hides or shaded areas the tortoise can retreat to. Rocks, cork bark, and low plants work great.

Outdoor Pens:

• Outdoor Keeping– This is the best way to keep Hermann’s tortoises. Natural sunlight, fresh air, and grazing space help them thrive. A garden-style pen works better than a huge pasture.
• Size– For one adult I would go minimum 6–8ft x 4ft. Larger is always better, especially for multiple tortoises. They don’t need massive areas like giant species, but room to roam is important.
• Have both- sunny basking spots and shaded areas. Hermann’s enjoy warm sun but will retreat during midday heat.
• Substrate– Natural dirt, sandy soil, dry grass, and edible weeds work best. Add rocks, small slopes, and varied terrain for enrichment. Avoid wet or swampy ground. Dry, well-draining soil is ideal.
• Shelter– Provide a dry hide or small house for sleeping and protection from rain or cold nights. In cooler climates, an insulated or lightly heated shelter may be needed during winter or brumation periods.
• Water Dish– Always provide fresh water. Use a shallow dish they can easily walk into and out of. They drink regularly but typically do not soak as often as tropical species.

Heating, Temperature & Lighting:

Heating:

• Heat Emitters & Deep Heat Projector– Great for creating warm zones without light. These help maintain steady daytime or nighttime temperatures, especially indoors or during colder months.
• Radiant heat panels – Ideal for heated night houses or insulated shelters. Provide gentle, even warmth and pair well with thermostats for safe temperature control.
• Oil filled heater– A good cost-efficient way to warm an entire room or shed if housing multiple tortoises indoors. Always keep safely out of reach.
• Heat mats– Can be used under one side of the enclosure or beneath hides for mild belly warmth. Use low settings only since Hermann’s prefer surface basking heat rather than strong bottom heat.

Temperatures:

• Day Temperatures: 75–85°F is ideal.
• Basking Temperatures: 95–100°F is what you want to aim for. Hermann’s tortoises love strong basking heat similar to their Mediterranean homeland.
• Night Temperatures: 65–72°F is ideal. Slight nighttime drops are natural and healthy.
• Winter Temps: In cooler climates bring indoors or provide a heated shelter. Hermann’s tortoises can safely brumate in winter if healthy and properly prepared.

Lighting:

• UVB Lighting– When housing indoors use a UVB bulb. Fluorescent tubes 5.0 or 10.0 work well. Mercury vapor bulbs also work if you have proper height and space. Natural sunlight outdoors is always best.
• Basking – Use a basking bulb indoors to create a clear warm zone for digestion and thermoregulation.
• Night time– Night lighting usually isn’t needed. If extra heat is required, use ceramic emitters or radiant panels instead of colored bulbs.

Substrate & Humidity:

• Substrate indoors– They prefer a dry, well-draining substrate. I would go with organic topsoil, coco coir, and a small amount of sand mixed together. Make it firm enough for stable walking and light digging. Avoid overly damp or muddy setups.
• Substrate Outdoors– Go with natural firm dirt, sandy soil, rocks, and dry grasses. Orchard grass, weeds, and edible plants work well for grazing. Add mulch or bark only in shaded hide areas if slight moisture retention is needed. Mediterranean-style dry terrain is ideal.
• Humidity Indoors– For indoors keep humidity moderate around 40–60%. Slightly higher humidity for hatchlings and juveniles can help prevent pyramiding, but overall this species prefers drier air compared to tropical tortoises.
• Humidity outdoors– Natural outdoor humidity is usually fine. Aim for 30–50% ambient humidity with access to shaded microclimates. Good airflow and dry ground are more important than maintaining high moisture levels.

Diet, Feeding, & Water:

Diet: (Herbivorous)

• Primary Foods: Grasses, timothy hay, orchard grass, weeds, dandelion greens, plantain, mallow, clover, hibiscus leaves and flowers, mulberry leaves, and other fibrous leafy plants. Hermann’s tortoises thrive on a high-fiber, low-protein grazing diet similar to what they would find in Mediterranean grasslands.
• Supplemental Veggies: Escarole, endive, collard greens, squash, cactus pads (nopales), and other dark leafy greens. Feed in moderation alongside grasses.
• Fruits (treats only): Small amounts of berry or melon occasionally. Fruit should be rare since excess sugar can upset digestion and lead to shell or gut issues.
• Supplements: Calcium powder is good to use a few times a week, especially for growing juveniles and breeding females. Helps maintain strong shells and bones.
• Commercial food: Mazuri Tortoise Diet or similar high-fiber pellets can be used occasionally as a supplement but should not replace fresh grazing foods.

Feeding:

• Graze daily on pasture or provide fresh weeds and greens every morning.
• Offer hay or dried grasses regularly to increase fiber intake.
• Commercial foods can be fed 1–3x a week as a supplement if desired.
• Primary feed should always be grasses, weeds, and leafy plants. Flowers and greens can be offered daily or every other day.
• Scatter food around the enclosure to encourage natural walking and foraging behavior.

Water:

• Fresh water daily is important for this species.
• Use a shallow dish they can easily walk into and out of.
• They drink regularly but typically soak less than tropical or humid-climate tortoises.
• Shade over the water dish helps keep the water cool, slows algae growth, and reduces evaporation.
• Even dry-climate tortoises still require consistent hydration.

Behavior & Daily Care:

• Diurnal– Most active early mornings and late afternoons when temperatures are mild. On cooler days they may graze and explore throughout the day.
• Midday heat– Will seek shade, hides, or lightly burrow into soil to avoid intense sun. Providing shaded areas, plants, and shelters is important for natural temperature regulation.
• Generally calm, hardy, and curious—often recognize caregivers and quickly learn feeding routines. Hermann’s tortoises are active walkers and spend much of their day grazing, climbing small obstacles, and exploring their enclosure.
• Soaking– They drink regularly and may occasionally soak, but typically do not soak as frequently as tropical species. A shallow water dish is still important for hydration and digestion.
• Handle minimally– Always support their full body when lifting. Tortoises can stress easily with frequent handling, so limit interaction and allow natural behaviors whenever possible.

Health & Common Issues:

• Pyramiding: Caused by improper diet, low fiber intake, dehydration, or overly rapid growth. Feed a grass- and weed-based diet with proper calcium and maintain moderate humidity for juveniles to encourage smooth, natural shell growth.
• Respiratory Infections: Often caused by cold, damp, or drafty conditions. Hermann’s tortoises prefer warm, dry environments. Avoid keeping them wet or chilled. Always provide a dry basking area and consistent heat.
• Parasites: Regular fecal checks are recommended, especially for outdoor tortoises. Parasites usually become problematic during stress, poor diet, or illness. Clean enclosures and good husbandry help prevent outbreaks.
• Shell Injuries: Use predator-proof enclosures and smooth fencing. Dogs, raccoons, birds, and other animals can injure small tortoises. Check shells and skin regularly for cracks, cuts, or damage.
• Dehydration: Even dry-climate tortoises still require fresh water daily. Lack of hydration can cause lethargy, poor appetite, and kidney issues. Provide shallow water dishes and occasional access to soaking.

Breeding & Reproduction:

• Breeding season– Usually begins in spring (March–May) as temperatures warm and daylight increases. Mating activity often ramps up shortly after brumation. Females typically lay eggs from late spring through summer (May–August).
• Sexual Maturity– Usually around 6–10 years, depending on growth rate, diet, and overall size. Males often mature slightly earlier than females.
• Clutch size– Females lay 3–8 eggs per clutch in sandy or loose soil nests. Many females produce 1–3 clutches per year when conditions are ideal.
• Incubation– Typically 60–90 days. Ideal temperatures are 84–88°F with moderate humidity. Warmer temperatures shorten incubation time while cooler temps extend hatch time.
• Hatchlings– Require warm, slightly humid enclosures and frequent hydration. Babies usually measure 1.5–2 inches at hatch and should be kept on soft substrate with easy access to food, water, and shelter.
