Husbandry requirements

Spur-thighed Tortoise — origin: Mediterranean basin: North Africa (Morocco, Algeria, Tunisia, Libya), southern Spain, the Balkans, Turkey and the Near/Middle East..

Terrarium temperature gradient

Night min15 °C
Cool side18–24 °C
Warm side28–32 °C
Basking spot35–40 °C

A heliophilic species requiring a genuine hot spot under a lamp. The night-time drop is beneficial. Healthy adults: brumation (hibernation) for 2-3 months at 4-10 °C; NEVER hibernate a sick, thin, dehydrated animal or a first-year juvenile without a veterinary check-up.

Enclosure (adult)
200 × 100 × 40 cm

Planted, sunny outdoor pen (ideal) or an indoor tortoise table

The outdoors is strongly recommended for a good part of the year; the dimensions given are an indoor minimum for one adult, to be enlarged for the large forms (ibera) and for any cohabitation. A partially buried fence (a burrowing and climbing species) and a dry shelter are mandatory. Avoid closed, humid vivariums.

Humidity
40–60 %

A Mediterranean to arid climate, so a rather dry, well-ventilated environment. Juveniles nonetheless need a humid hide and regular baths to limit pyramiding. Avoid stagnant, cold humidity (respiratory risk).

Substrate
Topsoil / fertiliser-free compostRiver sand (as a mix)Hay or straw as a surface layer

A loose earth-sand mix, deep enough to dig in. Avoid dusty substrates, resinous wood shavings and pure sand (risk of intestinal impaction).

UVB
Optional

Essential: a high-output UVB tube or lamp (10-12 % type / Ferguson zone 3-4), replaced according to the manufacturer's recommendations. Direct, unfiltered sunlight outdoors remains the best source.

Water source
Always available

A shallow dish of clean water available at all times. Regular lukewarm baths (especially for juveniles) for hydration and gut transit; prevent dehydration.

Origin
Testudinidae

Mediterranean basin: North Africa (Morocco, Algeria, Tunisia, Libya), southern Spain, the Balkans, Turkey and the Near/Middle East.

Feeding & health

Diet

Strict herbivore — None — animal protein must be avoided

Fibrous, calcium-rich wild plants: dandelion, plantain, clover (in moderation), thistles, mallow, mulberry leaves, timothy hay. A high Ca:P ratio is essential; cuttlebone ad libitum and calcium supplementation. Avoid fruit, water-laden vegetables, excess brassicas, rich pellets and any animal protein (risks of urinary stones, abnormal growth and pyramiding).

Breeding
Oviparous

Clutch 4–15 eggs/young. Several clutches per season are possible; incubation ~55-90 days with temperature-dependent sex determination (TSD). PROTECTED SPECIES: listed in Annex A of the EU regulation (CITES Appendix II) — keeping, transfer and breeding are strictly regulated, mandatory documents (intra-EU certificate / CITES). Taking from the wild is prohibited; wild individuals are stressed and often carry parasites and herpesvirus (TeHV).

Health watch points
  • Metabolic bone disease (MBD) from calcium or UVB deficiency
  • Herpesvirus (TeHV) and respiratory infections / runny nose syndrome (RNS)
  • Shell pyramiding (abnormal growth linked to diet and humidity)
  • Internal parasites (pinworms, flagellates), especially in wild individuals
  • Bladder stones (urolithiasis) linked to dehydration or excess protein

Frequently asked questions

Answers to the most common questions about keeping the spur-thighed tortoise.

What size can an adult spur-thighed tortoise reach?▾
Its size varies greatly depending on the subspecies: small forms such as T. g. nabeulensis barely exceed 12-15 cm, while large forms such as T. g. ibera can reach 25 to 30 cm. Females are generally larger than males, whatever the subspecies.
What lifespan should you plan for before adopting a spur-thighed tortoise?▾
This is a very long-lived species that frequently exceeds 100 years under well-managed captivity. Acquiring one is therefore a commitment spanning several decades, with the question of passing the animal on to be anticipated from the outset.
What enclosure and outdoor setup suit it?▾
The open air is strongly recommended for a good part of the year, in a planted, sunny enclosure of at least 200 x 100 cm of floor space for an adult indoors, to be enlarged considerably for the large forms or any cohabitation. The fence must be partially buried, as this is a burrowing and climbing species, with a dry shelter mandatory and no closed or humid vivarium.
What temperature and basking spot should you maintain?▾
A genuine basking spot between 35 and 40 °C is necessary, with a warm side at 28-32 °C, a cool side at 18-24 °C and a beneficial nighttime drop to about 15 °C. Healthy adults can hibernate for 2 to 3 months at 4-10 °C, but a sick, thin or dehydrated animal, or a first-year juvenile, should never hibernate without a prior veterinary check-up.
Does it need a lot of humidity, and what substrate should you choose?▾
No: its native Mediterranean-to-arid climate calls for a dry, well-ventilated environment, with a humidity level of 40 to 60 % over a loose earth-and-sand mix, deep enough for digging. Juveniles nonetheless need a humid hide and regular baths to limit pyramiding, and you should avoid dusty substrates, pure sand and cold, stagnant moisture.
What should it eat, and which foods should you avoid?▾
It is a strict herbivore: its diet should be based on fibrous, calcium-rich wild plants such as dandelion, plantain, clover in moderation, thistles, mallow or mulberry leaves, with cuttlebone available at will. You must rule out fruit, vegetables too laden with water, excess cabbage, rich pellets and any animal protein, which expose it to the risk of urinary stones and pyramiding.
Why is UVB so important for this tortoise?▾
Strong UVB, of the 10-12 % type or Ferguson zone 3-4, is essential and must be replaced according to the manufacturer's recommendations. Nothing, however, replaces exposure to direct, unfiltered sunlight outdoors, which remains the best source for this heat-loving species.
Is a water dish necessary despite its arid origin?▾
Yes, a clean, shallow water dish must remain available at all times, supplemented by regular lukewarm baths, especially for juveniles, for hydration and proper digestive transit. This also helps prevent dehydration and bladder stones.
Is its temperament always as docile as they say?▾
Generally yes, it is docile and easy to handle, but males can become aggressive during the breeding season, harassing and even biting females and other conspecifics. Some North African populations are moreover shyer and more sensitive to stress than the Eurasian forms.
Can you keep and breed this tortoise without any special formalities?▾
No, it is a protected species listed in Annex A of the European regulation (CITES Appendix II): keeping, transfer and breeding are strictly regulated and require mandatory documents such as the intra-EU certificate. Capture in the wild is prohibited, and wild individuals are often stressed, parasitised or carriers of herpesvirus.
How does its reproduction proceed in captivity?▾
It is oviparous and can produce several clutches of 4 to 15 eggs per season. Incubation lasts about 55 to 90 days, with temperature determining the juveniles' sex (TSD).
What health problems are the most common?▾
Metabolic bone disease, linked to a lack of calcium or UVB, and shell pyramiding linked to diet or humidity are the most common. Also monitored are herpesvirus infection (TeHV) with runny nose syndrome, internal parasites in wild specimens, and bladder stones promoted by dehydration or excess protein.
