Description

The flagfin shiner is a small, colourful North American cyprinid from the south-eastern United States. The species grows to about 7 cm and has a slender body with a conspicuous blue-black lateral band, a yellowish back and brightly coloured fins, to which the name refers. It inhabits flowing pools and runs of headwaters, creeks and small rivers, usually over sand and near vegetation. As a small schooling fish it feeds on small invertebrates, insect larvae and plant matter. Owing to its small size it is prey for larger fishes and has no fishery value. The species is harmless to humans.
