Identification
The upper body is dark, with numerous small brownish spots visible on closer inspection. Its tail is straight-edged to slightly rounded. A photograph of the whole fish and fins is more useful than color alone when separating small catfishes.
Size and Weight
Published maximum total length is 15 cm, approximately 5.9 inches. A life-history study also cites a maximum standard length of 12.4 cm, measured without the tail. No dependable maximum body weight was established.
Habitat and Feeding Research
Clear flowing springs and streams are characteristic habitat. A study of 298 fish from an Alabama tributary documented association with undercut banks, root masses and wood. Stomach-content work confirmed a diet comparable with other madtoms, but detailed prey proportions were not verified here.
Observation and Fishing Context
This small native catfish is primarily a subject for stream observation and identification. The checked research does not establish a recreational bait recommendation. Its sheltered habitat can make it easy to miss during a casual look into a creek.
Shelter Along the Stream Edge
Roots and woody debris create protected spaces within a flowing stream. Black Madtom’s recorded association with those features highlights the importance of more than the open gravel bed when considering small-fish habitat.
