Range and Identity
Phenacobius catostomus occurs in the Mobile system of southeastern Tennessee, northwestern Georgia and Alabama. This drainage-based distribution is more specific than an unrestricted southeastern range. A tributary name helps establish which portion of the system a collection represents.
Habitat and Behavior
Adults inhabit gravel and rubble riffles and runs in creeks and small to medium rivers. The two channel features can occur together while differing in depth and turbulence. Recording the actual occupied feature provides more useful context than relying only on the Riffle Minnow name.
Food and Life History
The upper reference is twelve centimeters total length, with 7.5 centimeters given as a common size. A detailed diet, migration pattern and independent maximum weight are not established in the retrieved summary. Those details should be tied to this species before being added from a related minnow.
Field Note
Preserve the substrate and current with a locality record. A named stream can contain many habitats, while the occupied gravel or rubble patch gives a much clearer picture.
