First of all, how large is your current RES? Do you know how large the RES on craigslist is? If you want to keep two turtles together, than you need to make sure they are the same size. It might be easier for you to house them separately, though, in the future.
Before introducing the two turtles, the new should be quarantined for 90 days (3 months). The new turtle could be sick or carrying something else you don't want your current turtle to catch.
When you introduce them, let them meet each other in a storage bin, without water. I have noticed that a turtle's aggression seems to be higher in they are in water. If all goes well, then try seeing how they react when in water together. If they are too aggressive as in biting and chasing, then they should not live together.
