I live in Craig Creek, Who am I?

This is the largest native minnow in Virginia. If you look closely at the mouth with a hand lens, the fish lacks a frenum and has a small barbel that is at the posterior edge of the lips. The scales have dark margins. Lateral line scales are typically 44-47 - fewer and larger than its closest relative. In juveniles there is a midlateral dark stripe - look for that.

What is this species?

Who is the closest relative? How do you tell them apart in the field?


  1. Fallfish (Semotilus corporalis)

    The closest related species is the Creek Chub (Semotilus atromaculatus). The creek chub has a dark spot on the anterior base of the dorsal fin, while the Fallfish does not.

  2. correct!

    the large scales and dark scale margins makes this fish easy to id in the field
