Interior River Range
The distribution includes the Ohio basin and several other interior systems, including Ozark and southern drainages. These are separate river populations. The common name mountain should not be used to impose a particular elevation on every documented locality.
Rock and Vegetation
Adults occupy clean rocky riffles, shoals and runs in rivers of different sizes, often near vegetation. Plant cover can occur within moving water. Record the immediate current and bottom rather than treating every vegetated observation as a quiet pond setting.
Food and Size
Larval aquatic insects dominate feeding records, with mayflies particularly important. The maximum reference is thirteen centimeters total length. A smaller common-size entry can reflect the fish represented in an account and should not replace the upper size or be assumed to describe every mature individual.
Describe Current Around the Cover
Vegetation and flowing rocky habitat are compatible. Keep both features with a Mountain Madtom observation rather than choosing only one.
