Welcome to the Tortoise Forum!!
May we know appx. where in the world you are? And what would you like us to call you?
In my opinion, it wouldn't be a good idea to put a Russian and a wood turtle in the same habitat. They each require very different types of habitat, the Russian being from the dry steppe in Afghanistan, and the wood turtle coming from a more humid, forest-like environment. It would be hard to provide those two types of habitat in one container.
Also, they each have their own pathogens that they have evolved with and get along with. When you mix species, you run the chance of having those different pathogens make the other specie sick or even dead.
