Description

The redline darter (Etheostoma rufilineatum) is a small, brightly coloured perch of the family Percidae from eastern North America. The species has an elongate body with a pattern of red-brown lines and spots, especially vivid in breeding males, and reaches only about 8 cm. It inhabits clear, fast-flowing rocky riffles of creeks and small to medium rivers. As a bottom dweller it feeds on the larvae of midges, blackflies, mayflies and caddisflies and on water mites. The eggs are buried in the substrate. Owing to its sensitivity to pollution the species is an indicator of clean water.
