I thought N. rubellus for the Notropis at first, but the snout appears too short and the eye a tad too big. I'm not good with Moxostoma, but the caudal peduncle seems a bit too stout for M. duquesnii.
As far as the Notropis....you could be right as the eye looks a little big but it's not exactly central to the snout which I expect in N. atherinoides. The Mox exhibits the color pattern of M duquesnei and too many scales for other possible mox.
