fallfish

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.
