flavus Rafinesque, 1818
contributors to this species:
Division of Natural Areas and Preserves
is commonly called the 'Stonecat' because of its tendency to hide
beneath flat rocks in fast flowing riffles and runs among
stones on the river bed, where it resides in moderate to
large streams. Inhabits rubble and boulder riffles and
runs of creeks and small to large rivers, and gravel shoals of
lakes. Adults feed on mayfly larvae and crayfish. The body is
slender, and compressed posteriorly; the head and nape are broad
and depressed; the mouth is subterminal; eye small to moderate.
The pectoral spine is straight; the surface usually only roughened,
and lacking prominent serrae. The genital papilla is conical and
a ventral apical notch is present. The upper jaw projects beyond
the lower jaw. The tooth pad on the upper jaw has a narrow, crescent-shaped
extension on each side. The notch between adipose and tail fins
are closer to tip of tail fin than to the dorsal fin base. The
dorsal fin has 1 spine, (5)6 rays. The upper caudal rays number
(27) 29-33(36) and the lower caudal rays (26)27-31(33). Anal rays
15-18(19); pelvic rays (8)9-10; the pectoral has 1 spine and 9-11
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.
