Relevant Information: |
The genus Auchenipterus
is closely related to and is similar to, Epapterus
and Pseudepapterus. Distinguished
from all species except A.
brachyurus by the following combination of characters:
anal fin origin posterior to the middle of the body; and caudal
fin without terminal band, but with a chevron-shaped dark mask
near base of each lobe. 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. 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 join in. Remarks:
This species will not be seen too often in the hobby. Can be
kept in lower temperatures due to its southern habitat. |
