The Neotropical auchenipterid
catfish genus Auchenipterichthys includes
four species. Auchenipterichthys thoracatus,
formerly considered to be widely distributed throughout
the Amazon River basin, is found to be restricted
to the upper Madeira River basin. The widespread Amazonian
species that had been misidentified as A. thoracatus
is, instead, A.
a species that also occurs in the upper Essequibo
River. Auchenipterichthys longimanus, the
most widely distributed species of the genus, is found
through much of the Amazon and Orinoco River basins.
The fourth species of the genus, A.
punctatus (and its junior synonym
A. dantei), is found in the upper portions
of the Orinoco and Negro River basins in Venezuela
and the central portions of the Amazon River basin
in Brazil. (Ferraris et al 2005). Aquarium
Care: Good community catfish with normal
sized patrons but not to be trusted with small Tetras
for instance, which will be picked of at night on
its twilight patrols. Breeding: This
family practice internal fertilization with the female
depositing the fertilized eggs on aquatic vegetation
with no care of the eggs shown. An unsuccessful breeding
report states that the male swims behind the female
and they suddenly lock their pectoral, female's adipose
and caudal fin. They speed around the tank and are
oblivious to anything around them. After this confrontation
they break apart and fall to the aquarium floor where
they sit for a couple hours in a "dazed"
condition. Diet: Can be fed most
aquarium fare such as good quality flake, white worm,
tablet and pellet foods and frozen foods such as bloodworm.
Better to feed at lights out until they get accustomed
to the daytime feeding regime when they may very well
South America: Lower and middle Amazon, Tocantins, and
Orinoco river basins. Type locality:
River Capin, Para [Brazil].
