I just sold off all of my turtles/tortoises, except for my wifes russian female tortoise. We feed her mazuri tortoise chow, wet it down dont make it soggy but the dampness makes it alittle bit easier for them. Also greens like spinach, and baby greens are great for them. They love berrys like raspberrys. Also as far as their habitat goes, make sure you have plenty of substrate for them russian tortoises are diggers, they love to dig. This will make them feel more at home. As far as your friends ebt goes I would probaly just stick with box turtle food, possibly some greens and berrys here and there. Im sure that Mazuri has box turtle food. Goodluck to you and your new friend.
