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. |
