The pygmy madtom is among the least frequently encountered North American fishes, documented from limited reaches of the Duck and Clinch river systems in Tennessee. Moderate river current over gravel and rubble, often near clean shoals. Its scarcity and patchy records make intact river processes and water quality more important than sighting attempts.
Resident year-round; it is exceptionally difficult to detect and should not be pursued. Never seine or turn rocks for this protected fish; learn at public river overlooks without entering sensitive shoals. For Pygmy Madtom, the cited federal or Tennessee wildlife source documents Tennessee as the endemic or core primary range.
