Personality & CharacteristicsThey are generally active during the day, less aggressive to each other (unless during mating). They are good borrowers and climbers. Mostly comfortable at their environment.Only different from the greek tortoise in; Russian tortoise becomes relatively shy in new environments.
DietGreek tortoise should be fed with a mix of vegetables and grass. Fruits should only make 10% of their diet. Also, a shallow dish with water should always be available to ensure the tortoise stay hydrated.Same as the greek tortoise with the only difference being that you can also feed the Russian tortoise with hay, carrots, squash and bell peppers.
Housing During the warm season of the year, this tortoise should be built spacious enclosures on the open. There should be plenty of vegetation to feed on. Due to their curious nature, the enclosure should be dig proof as they can borrow down and escape. Also, the height of the walls should average between 6-12 inches tall. Housing greek tortoise in glass tanks in the open should be avoided at all cost as this will generate a lot of heat and kill the animal.

Under indoors housing, large plastic is preferred or 40 gallons of the terrarium.
Same as the greek tortoise.
Temperature & LightingWhen housed indoors a greek tortoise requires approximately 12-14 hours of UVB light. This light can be provided by mercury vapor bulbs and is essential since it helps in providing vitamin D3 necessary for the healthy growth of the tortoise.

A temperature of around 95 degrees should be maintained in the basking areas and at night the temperatures can fall to approximately 65-75 degrees.
Have similar requirements as the greek tortoise. The only difference is that a room temperature of 80 degrees should be maintained in the lows and 95-100 degrees in the basking area.
Bed & SubstrateA mix of top soil and play sand, cypress mulch, and aspen shaving are the most appropriate to use. Pine and cedar bedding should be avoided as they are toxic to the tortoise.Due to their borrowing nature, the russin tortoise should be provided with a fairly deep layer of beddings. The most appropriate bedding would be: shredded aspen, clean soil, reptile bark, and cypress mulch
HibernationThe greek tortoise hibernates during the cold seasons.They hibernate during winter and the cold season.
Breeding After hibernation the female tortoise becomes receptive. The male makes advances on the female by ramming their shells. One mating is enough for the female to lay many eggs. Females become aggressive few days before laying their eggs. They borrow on a place they find appropriate and cover their eggs with sand.Mating occurs after hibernation where the male makes advances on the female by: robbing its head, circling the female and in most cases biting the front legs of the female. The female is at first uninterested but they finally mate. Single matting is enough to fertilize 30 eggs. The female can delay her gestation period. When the time comes she finds and appropriate place to borrow and lay her eggs.
HumidityThe humidity level should not fall below 50%The Humidity should satay around 60% in their housing.

For both types of tortoises, if the correct humidity can not be achieved with outdoor housing then you must have indoor housing to maintain the correct percentage of humidity.

If this is not done, health issues can arise including shell rot.
