Habitat: The
elegant madtom is found primarily in Tennessee and
northern Alabama, in the upper and lower portions
of the Tennessee River, and also in the Roaring River,
the Green River drainage, Dunn Creek, Tennessee, and
in Piney Creek, Paint Rock River, and Flint River,
Alabama. It can be found in lower north-central Tennessee
rivers, such as at Little Chucky Creek in Greene County.
The elegant madtom was also found in central Kentucky,
in the Green River drainage. Its status in Alabama
is unknown. N. exilis was misidentified in
1996 at Bear Creek, Alabama, as N. elegans.
This mis-identification could be a reason for a small
decrease in the overall population size. According
to surveys there are very low numbers of the elegant
madtom in the middle and upper Tennessee River drainage.
The survey reports that these low populations could
be due to the lack of available nesting sites, as
it prefers habitats with riffles and rocks to nest
under. However, the elegant madtom is common in the
Green River and lower rivers in Tennessee that are
close to Alabama. Reproduction: Approximately
a year after emerging from its egg, the elegant madtom
will reach sexual maturity. Then, after this year
of growth, a member of Noturus elegans will
find a mate and make a nest beneath a rock in a river
or stream. Rocks are very important for the elegant
madtom, because without this substrate to lay their
eggs under, they will not have the ability to make
an effective nest that they can protect. 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: The elegant
madtom from immaturity to adulthood is an invertivore,
which means it feeds on invertebrates. It is only
common in a few places, and faces predation from larger
fish such as the largemouth bass and catfish. However,
the elegant madtom does have a defense in its venom
delivery system, a venom delivery gland in its pectoral
and dorsal spines to deter potential predators or
competitors In the Aquarium they will also take tablet
and pellet foods. A varied diet will keep them in
optimum health. Remarks:
The elegant madtom is not listed on the endangered
or threatened federal or state lists. Scientists who
have done surveys on the fish have recommended that
it should be listed as threatened.
