Shiner ID

[Fossil Fish]

I spent yesterday fossil hunting and fishing in SW Ontario. While at the fossil site, I took a couple of breaks from the heat and fished the Ausable River that runs thru it. Of course the only spots I was getting any bites were right beside rotting carp carcasses so the smell was a bit nasty, but who cares, I was getting bites. My first catch was a shiner I need some help with. It looks to me to have 8 anal rays, not much of a dark butt and in person, looked a lot more transparent than the pics show, but that could be just a thin fish being held up to the sun. Anyway, that is all leading me to think ghost shiner, but if I'm wrong on the ray count, then sand shiner. Just to make it more difficult, in the same little area, I caught my first (and 2nd and 3rd etc.) spotfin shiners. They also have 8 rays and juveniles lack the spot on the fin. Any thoughts????

At another spot further along, I caught another shiner, maybe the same, maybe not. This one had some beautiful metallic red stripes along the sides and a metallic green stripe along the back. Thoughts???
