The "fish" is either a common or striped shiner. Both are very similar as Shawn eludes to. When I was first in this "business" the striped shiner was a subspecies of the common shiner. Then some fish taxonomist decided they were separate species. Very little difference between the two fishes. Longitidunal Stripes across the back is about the only difference between the two species.
