he Loricariids of the Hypancistrus genera
in the middle and lower Rio Xingu
in Brazil are very alike with wormline, spotted and
squiggly black and white body patterns. Juveniles
have a very different colour pattern to the adults
and individuals can differ in colouration and body
shape. Juveniles tend to have a naked pale abdomen
and the adults sport a partly covered abdomen with
blackened patches. The Hypancistrus genera
are similar to the Panaque/Panaqolus and
Peckoltia genera but have fewer and larger
teeth in the lower and upper jaw.
has now been established (Cardoso, A. L.
et al. 2016) that this species and L333
are the same species and if they are kept together
in the same tank there is a possibility of cross breeding
between them. They are in fact differently marked
variants (phenotypes) of the same species.
L066 is found
in the lower stretches of the Rio Xingu but it is
reported that they have been introduced to the middle
regions also by local fishermen, forming stable populations.
Tiger Pleco, L066, L333
Xingu ( Belo Monte - Vitoria).
Body high with plates covered
by small, robust odontodes; operculum evertible; in
juveniles abdomen uncovered.
Basal colouration white/yellowish,
with blackened vermicular markings and banded fins;
the vermicular markings vary from narrow and closely-spaced
to large and well dispersed.
Care & Compatibility
No problem with keeping in
groups but only one Hypancistrus species
to a tank as there has been reports of hybridisation.
Provide some water movement in the aquarium with a
sandy substrate, caves and rockwork to provide hiding
places. No problem with other non-aggresive fish in
a community tank. They prefer water that is on the
warm side (26-30°c), soft and slightly acidic.
Males posses a broader and
longer head and odontodes on the posterior part of the
body, behind the gill covers and on the pectoral fin
spines. The latter two are a lot shorter in the females.
Has been bred successfully
in the hobby. Will lay 20 to 30 large eggs. Leaving
their cave the youngsters can be around the 1.5cm.(¾ins)
length. The male is responsible
for the brood care.
Omnivores, juveniles are keen
on vegetable foods whereas adults are less so. Frozen
foods such as brine shrimp, mosquito larvae and mussels
as well as tablet foods.
Hair - like stuctures on the body. Operculum: The bony covering of the
gills of fishes. Pectoral: The paired fins just behind
hypo = under + Greek, agkistron = hook.
