riffles and runs near debris and among tree roots along undercut
banks in creeks to large rivers. Feeds on aquatic insect immatures
dominated by mayflies, caddisflies, midges, and blackflies. This
species is moderately robust. Body has a uniform colour of a brown
back with the sides lighter with dark freckles. The belly is yellowish.
The base of the median fins are dusky and lighter towards the
edges, margins are clear. The head is depressed, rounded above

fin spine with anterior edge smooth, posterior edge roughened
or with 3-5 serrations, poison gland at base. As with most of
this genera, handle with care. Anal fin is short, 15-20 rays.
Aquarium Care: The Madtoms are well suited to
aquarium life. Provide river gravel and smooth rounded stones
for hiding places during the day. A power filter at one end of
the tank will provide the conditions of a flowing stream for these
catfish. Can be housed with other North American fishes such as
minnows, darters and shiners. Diet:They like
most meaty food, such as cut-up earth worms, frozen blood worm
and prawns. They will also take tablet and pellet foods. A varied
diet will keep them in optimum health.
North America: Mississippi
River basin from northern Illinois to Louisiana, and from
eastern Kentucky tocentral Kansas and Oklahoma in the USA; Gulf
Slope drainages from Mobile Bay in Alabama to Guadalupe River
in Texas, USA.
