Description:
The adipose fin is nearly free from the caudal fin.
The caudal fin is straight or slightly rounded. The
pectoral spine has 4-10 large teeth on the rear edge
and several large teeth on the front edge. The anal
fin has 14-16 rays. Habitat: Inhabits
pools and backwaters around slab rocks, bedrock ledges
and tree roots in clear creeks and small rivers. The
Yellowfin Madtom has a stout body with the deepest
point located in front of the dorsal fin. Colouration:
The body is yellow with dark mottling, specks and
4 dark saddles above, and is yellow to white below.
A brown saddle in front of the dorsal fin usually
encloses 2 light spots. The fins are yellow with dark
bands or mottling at the middle and near the edges.
A bold black bar on the base of the caudal fin extends
from the top to the bottom of the fin. The dark saddle
under the adipose fin extends to the edge of the fin.
The caudal fin has a pale edge. 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.
