Variegate Darter

Etheostoma variatum is large in size for its family; it has an average length of between two and a half and three and a half inches (6 and 9 cm). It has a wide variety of markings. There is a red-orange band on its dorsal fin, which is followed by a blue-green band and a red-brown band at the edge of the fin. There are also red spots located on its other fins. This darter has large pectoral fins, which are used to keep the fish upright in the fast-moving streams it inhabits. It also has four to six saddles along its back. Three to four of these saddles tend to be dark and visible while the remaining saddles are not.

Etheostoma variatum lives in small and medium rivers and streams. They tend to live within riffles that contain small rocks. The darter will tend to live in the fastest flowing riffles. In order to survive, it needs rivers and streams with high water quality. Due to this attribute, the fish is often viewed as an indicator of good water quality. The darter lives predominantly in the states of Ohio, New York, Pennsylvania, Indiana, West Virginia and Kentucky. It has also been found within Virginia, although only rarely.

The diet of E. variatum consists of crustaceans, insect larvae and other aquatic invertebrates.
