Relevant Information: |
Inhabits rocky riffles, runs, and
flowing pools of clear creeks and small rivers. Rarely found
in springs and along wave-swept margins of large impoundments.
Feeds on aquatic insect immatures (midges, mayflies, caddisflies)
and small crustacea (isopods, amphipods, copepods). The Slender
Madtom has black borders on light yellow fins. Fin borders are
blackest in clear streams and may be only dusky in colour in
turbid water. The body is yellow-brown to gray-black above and
light yellow below. There is a large light yellow spot on the
nape and a smaller one on the rear of the dorsal fin base. The
body is slender, and the mouth is terminal with equal jaws.
The rear edge of the pectoral spine has large teeth. The caudal
fin edge is straight or slightly rounded. The anal fin has 17-22
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. |
