Description:
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. Habitat:
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.
Colouration: 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. 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: Feeds
on aquatic insect immatures (midges, mayflies, caddisflies)
and small crustacea (isopods, amphipods, copepods).
In the aquarium 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.
