Relevant Information: |
Inhabits rocky riffles and runs
of clear, fast creeks and small to medium rivers. 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. 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. |
