I would suggest a nice soak (at least 20 minutes) several times a week in lukewarm water. Also, my Russian got more active when we made his enclosure brighter with a lamp. Finally, try aloe, collard greens in his diet. Good luck!
Not a Russian, we have a Russian Tortoise, and he looks nothing like your guy. I hope you can identify the species, & give him the care and love he needs! Good luck!
We have a Russian Tortoise. Yes, yours looks to be pyramiding. You should not let it roam freely around the apartment. You can get a big Rubbermaid container, put substrate in
It, with a hideout and some water. These guys love to (and need to) burrow (especially at night). We have a heat lamp...
Aww, we have a Russian Tortoise, Sheldon, & love him. ❤️ I hope you find the owners, or can keep him. He should be soaked daily since he is a baby. They love to “hide” & burrow too, & need a heat lamp during the day, not too cold at night. We give Sheldon Raducchio, spring mix, dandelions...
