Pond Boss Forums INTRO Questions & Observations Minnow ID please

Those are all shiners and the largest one (last pic) is a common shiner. Not positive about the ID of the smaller ones. Let's see what CJ says. Notice the dark or dusky spot at the front base of the dorsal fin of the smaller shiners. This is likely a 'key' character. The northern redfin shiner has this character which is what I think they are. IMO they are not common shiner because the insertion of the dorsal fin of the smaller shiners is slightly behind the pelvic fins, a feature not displayed by common shiners.

None of those photographed in the bag will be a problem in the pond but they might not spawn. We have found out from another member here that common shiners will spawn in a pond if there is current or splashing current from something like a waterfall.
