Pseudancistrus pectegenitor
can be diagnosed from all other Pseudancistrus by having
10-11 dorsal fin rays (vs7) and adpressed cheek
odontodes reaching to three or more plates beyond the opercle
in adults (vs. maximally to rear edge of opercle); from all
other described Pseudancistrus except P. sidercus
by having the plates of the ventral row of the caudal peduncle
with dorsal laminae strongly concave, accentuating the
medial keel of the ventral plate row (vs. ventral plate row
slightly convex, Armbruster, 2005); and from all other Pseudancistrus
except P. coquenani, P. orinoco, and P.
yekuana by having large oral papillae
proximally on each dentary just internal to the tooth cup (vs.
papillae absent) Pseudancistrus pectegenitor can be
further diagnosed from P. coquenani, P. orinoco,
and P. yekuana by having a larger pectoral-fin spine
(38.3-42.2% SL vs. 22-0,31.4) and from P. coquenani,
and P. orinoco by having a a smaller head-dorsal length
(5.6-6.8% SL vs. 8.0--12.2). 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. Adult
males are very territorial and will not get on with other large
Loricariid catfish. 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: Inhabits flowing
water associated with large rock outcrops in main river channel. |
