Relevant Information:

Noturus flavus 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.
