I was sure that I saw N. hudsonius today at a local creek event today. We definitely had them in the aquarium. But I netted a random minnow (making sure not to get the Cyprinella) and photoed one. But I didnt pay attention, I was just taking the photo. Now when I look at it, I dont think it is hudsonius... kinda looks like a Hybopsis to me.

Help, now I am doubting myself and I cant decided either way?

That is a tough one. It doesn't quite have the eye shape of a hudsonius, but the dorsal scales seemed shaped more like hudsonius. Not a terribly punctuated lateral line like a hudsonius would have. When I look at Peterson's, Marcy's, and Fritz's book it seems to have more individual hudsonius qualities to it, but when I just look at the photo it sure seems more like Hybopsis rubrifrons. I'm probably overthinking things and missing something obvious,though...

Does not seem to have that subterminal mouth that is common in Hybopsis. About all I can add.

To me it looks more like hudsonius than like rubrifrons; quite similar to Cape Fear and PeeDee basin hudsonius I've seen. Are there any other possibilities in that watershed?

Gerald, those are certainly the two most likely, since this is a direct tributary to the North Oconee, but we also have a Hybognathus (that I have never seen) according to Fishmap.org.

Not sure what your local Hybognathus is, but the H. regius I've seen in NC are plain silvery, no dark scale edging or lateral stripe, clear fins with no color, and a smaller eye than your fish pic. See Scott's Hybog pic here: http://www.ncfishes....thus-regius.jpg

I think your fish is hudsonius -- I see nothing in the pic that looks inconsistent with hudsonius

Thanks Gerald. You are much better at this silvery minnow ID than I am. When we were streamside I was sure they were N.hudsonius, but once I got home and looked more closely at the photo I got confused.
