The Best Pet Tortoise – Greek Tortoise and Golden Greek Tortoise Care

I do not believe that any tortoise species can be classified as “easy-to-keep”, but several are better-suited as pets than others.  I’ve covered on of these, the Russian Tortoise (Testudo horsfieldi), in an earlier article (read article here).  The Greek Tortoise (T. graeca), while interesting enough for the most seasoned hobbyist, may also be the best pet tortoise, and an ideal choice for first-time keepers.  Topping out at 8 inches in length, captive-bred individuals are readily available.  They are as personable as any of their relatives, and decades of popularity among European keepers has left us with a good understanding of their needs. I’ll summarize these in the following article, and will also draw from my own experiences with this and related species during my long career at the Bronx Zoo.

A Note on Classification

Also known as the Mediterranean Spur-Thighed Tortoise (not to be confused with Africa’s Spurred Tortoise, Geochelone sulcata), the Greek Tortoise is one of the smaller of the world’s 53 tortoise species.

Its taxonomy is somewhat complicated, with up to 13 subspecies being recognized.  Traditionally, T. g. ibera comprised the bulk of those in the pet trade, and it remains the most widely-bred subspecies.  The parent stock seems to have originated mainly from Turkey. Read More »

Tortoise Diets: Mediterranean Species and Russian (Horsfield’s) Tortoises

Hello, Frank Indiviglio here. Judging from recent questions posted on this blog, there is a great deal of conflicting information available as regards the feeding of tortoise. The Greek or spur-thighed (Testudo graeca), marginated (T. marginata) and Hermann’s (T. hermanni) tortoises, collectively referred to as Mediterranean tortoises, and the popular Russian or Horsfield’s tortoise (T. horsfieldi) require a vastly different diet than do desert or rainforest adapted species.

While there is some flexibility as concerns diet, there are some general rules that should be followed. The following protocol has worked well for me in zoos and at home, and will hopefully help you in caring for these responsive and interesting reptiles.

Protein and Natural Foods

Mediterranean and Russian tortoises have evolved to process a diet that is high in fiber and calcium and low in protein and fat. In the wild, they feed almost exclusively on grasses, herbaceous plants and flowers, with fruit only sporadically available.

In captivity, high protein foods such as beans and dog/cat food should be strictly avoided. Fruit is not necessary, although a few berries can be given as a weekly treat during the summer.

Native Plants

In the warmer months, I use native grasses, weeds and flowers for 75-85% of the diet, with such accounting for nearly 100% of some specimens housed in outdoor zoo exhibits. In addition to wild grasses, the following are some native and introduced plants that can be offered to tortoises:

Honeysuckle (Lonicera periclymenum)

Dandelion (Taraxacum spp.)

Hawkweeds (Pictis spp.)

Clovers (Trifolium spp.)

Cat’s ears (Hypochoeris spp.)

Mallows (Malva spp.)

Sedums (Sedum spp.)

Chickweed (Stelaria media)

Hedge mustard (Sisymbrium sp.)

Bramble (Rubus fruticosus)

Plantains (Plantago spp.)

Please see the article on Toxic Plants referenced below for a list of species that may be potentially harmful to tortoises.


The balance of the diet is comprised of seasonally available greens (stems and leaves) such as kale, endive, Swiss chard and romaine. Other produce can be added as available, but avoid spinach and iceberg lettuce and use bok choy sparingly. Small amounts of yam and carrot are provided once weekly.

Commercial Diets

Zoo Med’s Grassland Tortoise Diet  is specifically formulated for Russian and Mediterranean tortoises, and can comprise up to 50% of the diet in winter or summer.

Winter Diet

During the winter, the diet of tortoises under my care typically consists of 70-75% commercially available greens and 25-30% Zoo Med Grassland Tortoise Diet. Grated yams and carrot can be offered once weekly as a treat. Some native plants freeze well, and can be stored for winter use.


I add Reptocal and Repti Calcium with D3 to all meals provided to growing tortoises, and 3x weekly for adults. A cuttlebone is always available as well .

Water should always be available, or the tortoises can be soaked on alternate days, during which time they will drink heavily.

Light and Heat

Russian and other tortoises will not be able to properly metabolize calcium or digest other nutrients unless provided with a warm basking site and high levels of UVB (I suggest either the Zoo Med 10.0 or a mercury vapor bulb).
