Not so frequently occurring.
Caught in rapid zones where Pseudancistrus barbatus
lives although nothing is known of the ecological
relationship between the two species. The odontodes
on the extreme end of its snout and its pectoral spines
are very well developed. Aquarium care:
Not the easiest species to maintain in the aquarium
as it will need pristine water conditions with well
filtered water which should not be too hard. Warm
water should be the norm. Sexual differences:
Males have a broad head and posses long bristles along
the edge of the snout. Diet: Aufwuch
grazer, mainly vegetarian, with lettuce, spinach,
cucumber and courgette (zucchini), vegetarian flake
and tablets. Will eat other foods also such as insect
larvae, zooplankton and soft wood but will need to
be kept on a mainly green diet. Remarks:
This species in Fishbse is named Pseuancistrus
niger but in The Catalog of Fishes the current
status is Guyanancistrus niger.
