Fin's Fish Guide
The Longfin darter (Etheostoma longimanum) is a freshwater fish of the family Percidae that grows up to 9 cm.
Description
The longfin darter is a small perch of the family Percidae from the eastern United States. The species grows to about 9 cm and has a slender, mottled body; breeding males show blue-green and orange tints in the fins. It inhabits rocky riffles of creeks and small rivers with clear, fast-flowing water. Darters lack a well-developed swim bladder and 'hop' over the bottom from stone to stone on their supporting pectoral fins. As a bottom hunter it feeds on insect larvae and small invertebrates. Owing to its small size the species is harmless to humans.
