Information:
Habitat: Inhabits
rocky riffles and runs of clear, fast creeks and small
to medium rivers. Colouration: The
body of the Margined Madtom is yellow to slate gray
above and white or light below. The fins are yellow
or light gray and the median fins, except for the
adipose fin, have a black edge. Fin borders are blackest
in clear streams and may be only dusky in color in
turbid water. Individuals in the Dan River, Virginia,
have dark spots on the body and fins. Description:
The upper jaw projects beyond the lower jaw. The rear
edge of the pectoral spine has large teeth. The caudal
fin edge is straight or slightly rounded. The anal
fin has 15-21 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.
