Relevant Information:

Inhabits sand-gravel riffles and runs near debris and among tree roots along undercut banks in creeks to large rivers. Feeds on aquatic insect immatures dominated by mayflies, caddisflies, midges, and blackflies. This species is moderately robust. Body has a uniform colour of a brown back with the sides lighter with dark freckles. The belly is yellowish. The base of the median fins are dusky and lighter towards the edges, margins are clear. The head is depressed, rounded above with the upper jaw overhanging the lower. 4 pairs barbels. Pectoral fin spine with anterior edge smooth, posterior edge roughened or with 3-5 serrations, poison gland at base. As with most of this genera, handle with care. Anal fin is short, 15-20 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.
