These were caught in a small, private farm pond in central Florida. Look like many I've seen in field guides and online, but have seen many mislabeled internet photos. I'm guessing possibly weed shiner or coastal, but unsure. Any help would be greatly appreciated. Also sorry for the pic quality- amateur native aquarist; however, more green-gilled in the photography arena.

I'm kind of thinking maybe weed here, but the photos are not showing well the key distinguishing characteristics that are best used to separate Weeds from coastals when glancing at them. Could you give a description of the coloration on the anal fin? Particularly if there are darker markings on the fin rays and if present where at and how much? Also is there any darker lining of the scales below the Lateral stripe? Might be able to go a bit further with this information.

I have never seen texanus with reddish fish, but all I have seen are from Mississippi. The last pic kinda looks like a young golden shiner to me.

ya I think they are golden shiners, Notemigonus crysoleucas. I have seen them in a walmart pond in kisseme florida with redish fins like that. The ones we have up north here in ohio don't have the red but the body shape is the same.

here's a picture...

Yeah, the fact that they're from a pond strongly supports a golden shiner ID. I kept trying to get a good look at scales in the photos to confirm Cyprinella but that didn't really work. And the basicaudal spot is wrong. So golden it is.

I should have added mine is a ohio caught fish so it is missing the redish fins that the florida ones seem to have.

Are the fish in the first photo the same as in the second?
I hate ID'ing fish by blurry photos with little information.

yes, I figured it was possible for them to be juv. golden shiner, but I hadn't found anything that indicated that juv. golden shiner would have the solid black line along the lateral the way these guys have (all pics from same tank at same time, all similar in characteristics. Difference is flash/ no flash). I know for sure this pond had been stocked with golden shiner, but it has definitely had inflow and outflow from other sources, thusly I expected it could be a variety of other species that had potentially migrated from local rivers or streams to this small pond due to overflow from recent flooding from hurricanes and heavy rains from previous years.

Thanks for all the input, btw.

Also, I have been recently (2-4 weeks) feeding freeze dried bloodworms and freeze dried brine shrimp, along with spirulina flakes, so that may have some impact on coloration.
