Identify your North American Native Fish

Well, it seems as though I may the last one with you here. Escambiae or Dispar would be my best guesses, I'm not well versed in topminnows and killies, though.
 
I have no pics to post, so I have been waiting this out, but F. blairae?

The eye looks too small for cyprinodon variegatus sheepshead minnow but that's what it looks like otherwise.

Is it a sheepshead minnow?
