I agree with everything Anthony said about the pellets. Specially it couldn't be that exact zoo med pellet since it only came out in the last 2-3years haha.
Only one thing i dont agree on though. Its that its a Trachemys scripta scripta. Its defiantly in the Cooter family. Head markings are classic cooter markings. Unfortunately it has no shell patterns to which to go off of for me to ID an exact subspecies though it does look like the side of plastron might have a reddish tint to it so I'm leaning towards a Florida Red Bellied.
