The fin placement of those shiners in the close up pictures indicates these are emerald shiners. The origin of the dorsal fin for the common shiner is almost vertical or directly above the insertion of the pelvic fin whereas for the emerald shiner the insertion of the dorsal fin is well behind the origin of the pelvic fin as in shiner2 picture.
