The fallfish (Semotilus corporalis) is a species of freshwater ray-finned fish in the family Leuciscidae. The fallfish is the largest minnow species native to Eastern North America. == Description== Average specimens generally measure about in length, but individuals occasionally grow to with exceptional specimens of more than having been recorded. Juvenile fallfish have a dark stripe that runs down the center of their body. They are a silvery shade on the top and sides of the body, but have a white shading on the belly. Breeding males develop a pinkish tone on the opercular region, although the species does not develop bright breeding colors. Spawning males build stone nests, known as a redd, which form a prominent part of the bottom on many streams throughout the northeast. Spawning is communal with both males and females joining the nest builder. ==Distribution and habitat== Fallfish are found in the northeastern United States and eastern Canada, where they inhabit clear streams, lakes, and ponds. They predominantly prefer swift currents, however, they can also be found in well oxygenated pools. As their name suggests they are often found at the base of waterfalls. Before the introduction of fish such as smallmouth bass, largemouth bass, and brown trout, the fallfish was the apex predator in many streams.
