Hope you plan on keeping them. Not to be a negative nancy, but RES are an invasive species in most of NA and out compete native turtles and decline their population because their are so many of them and 90% of people that buy a turtle, which is usually a RES because they're cheap, and then let it go when it gets too big and too much time to take care of. There are turtle rescues all over NA filled to the brim with RES's that people didn't want, bringing more in on purpose is sort of looked down upon by turtle keepers because there is such a problem with them.
