    Definitely not sure about Fishes C and E...But I believe A is a common shiner (Luxilus cornutus), Fish B is a greenside darter (Etheostoma blennioides), Fish D is a redline darter (Etheostoma rufilineatum). Could be wrong though.

    correct on Fish B is a greenside darter (Etheostoma blennioides), Fish D is a redline darter (Etheostoma rufilineatum). Fish A -- you have the correct genus - Excellent. and the common shiner is very closely related to this species.

    -the orange dorsal fin gives it away
