Looks like you found some new species.
First two are western blacknose dace and the last few are central stonerollers.
Ugh, already have those, still looking for the Eastern Blacknose.
Thanks for the id's going out again today if the weather is ok.

Eastern blacknose dace (atratulus) is supposedly in the Roanoke basin and northward. The New (Kanawha),Yadkin, Santee (Catawba, Broad, Saluda), Savannah, Tennessee, and Gulf drainage populations should all be Western (obtusus) according to recent genetic studies. Separating them visually is pretty near hopeless; both are quite variable in appearance. I imagine they'd be very susceptible to "headwater stream capture" between drainage basins, and bait bucket transport in areas where their ranges are close. I'm guessing Dustin's ID of "western" is based only on location, right?

You need a good old fashioned whoopin'.
I'm glad someone else brought this up. I have to assume Josh was very sleepy, intoxicated or not wearing his glasses...

Completely on location Gerald. I have no idea what the differences in appearance are, if there even are any.
