The differences between the Panaqolus and
the Panaque genera is that the latter has
an oval shaped mouth and the jaws have very large
spatulate teeth with a single cusp, arranged in a
v form and Panaqolus have a small number
of spatulate teeth and are also a smaller genus. Panaque
armbrusteri is diagnosed from all members of
subgenus Scobinancistrus by having greater
than seven dentary and premaxillary teeth (vs. three
or four dentary and premaxillary teeth), by dentary
and premaxillary tooth cusps being unicuspid (vs.
bicuspid), and by dentary and premaxillary tooth cusps
being short and ladleor spoon-shaped (vs. main tooth
cusps being long and spatulate); and from all members
of subgenus Panaqolus by having a body color
pattern consisting of alternating dark brown to black
and light brown to gray longitudinal stripes (vs.
body colour pattern consisting of spots or vertical
and/or oblique bands), by individuals, 114 mm SL having
a hyaline caudal-fin window (vs. caudal fin uniformly
opaque, banded, or spotted), and by reaching a maximum
adult size of at least 345 mm SL (vs. ,150 mm SL).
Aquarium Care: This species is a bit robust
in an aquarium set-up so would need plenty of hiding
places, plenty of water changes, due to their wood
eating habits, and powerfull filtration. Needs a spacious
aquarium. Diet: All Panaques
and also the Panaqolus genera are wood eaters
so would need this in an aquarium set-up. Feed also
vegetable foods such as cucumber, courgette (zucchini)
and sinking tablets. See further information from
the reference, Lujan et al. Remarks:
The type species ofP.
armbrusteriis in theTapajós River and its tributaries
but there are three other similar populations in the
Xingú, Araguaia and Tocantins rivers to the
east.These populations are still
to be studied. The colour differences to these populations
is that P. armbrusteri has a greenish/brown
colouration and a pattern of very thin lines.
