About the Hermann's Tortoise
Hermann's tortoises are Mediterranean species that thrive on a varied weed and flower diet and, unlike grassland species, can take a little fruit occasionally. A typical adult weighs about 0.5–3.5 kg.
What to feed
Most common pet tortoises (Hermann's, Russian, leopard, sulcata) are herbivores that thrive on high-fibre weeds, grasses and leafy greens, with calcium supplementation and limited or no fruit. Grassland species especially need grass and hay, not fruit or protein.
Tortoises are typically fed daily or almost daily on a large volume of low-energy, high-fibre plants — they graze rather than eat rich meals. Feeding rich foods causes fast, lumpy shell growth (pyramiding).
