is an ideal community catfish as it is quite a hardy
character living quite happily in different water
conditions as long as they are not too extreme and
they are aclimatised slowly to them. They are not
too happy when the nitrates rise to an unacceptable
level, so keep the water changes up if you experience
high levels, or plant heavily as they don't seem to
was listed for many years as Ancistrinaesp. (L127) due to the overlaps of traits
to different genera. It was given two L-numbers, L127
(DATZ 05/1993) and L207 (DATZ 03/1996) which are one
and the same species. As of the paper by Armbruster
et al. (2015) this species has now been moved into
the Peckoltia genus and described and also
the sub-family Hypostominae.
There are over
50 species (2015) in this genera, described and non
described (L-numbers), and most of them are very difficult
to put a name to unless you have a location specified.
Work is still being done on the Peckoltia genera,
plus the genus Hemiancistrus which are very
alike. The colour patterns in Peckoltia tends
to go from a spotted head to brown bands on a lighter
Not the most colourful
of catfish but if you are starting out with a tentative
dip into the large and diverse species that makes
up the Loricariids you could do no worse than the
Peckoltia genera and a start with Peckoltia
The specific name
is in honour of the former graduate student of JWA,
Dr. Nathan Lujan. Dr. Lujan who has led expeditions
to some of the most remote regions of South America
and obtained some of the most important specimens
for the study of loricariid systematics specifically
as well as South American fish systematics and ecology
Amazonas. Type Locality: Venezuela,
Amazonas, Río Orinoco at Paso Ganado, 38 km
NNW of San Fernando de Atabapo, 04.3842°, -067.7747°
Body moderately elongate. Head
and nape forming arc from tip of snout to anterior
of parieto-supraoccipital, rising more rapidly to
parieto-supraoccipital crest, and then more slowly
to dorsal-fin. Dorsal slope decreasing in straight
line to insertion of dorsal procurrent caudal rays
then ascending to caudal fin. Body depth greatest
below insertion of dorsal fin. Ventral profile flat
to ventral procurrent caudal-fin rays, and then sloped
ventrally. Caudal peduncle oval in cross section with
dorsal and ventral surfaces flattened. Body widest
at insertion of pectoral fins, narrowest at insertion
of caudal fin. Snout rounded.
Base colour light tan with
brown to black markings. Four dorsal saddles on the
body, the first below the middle rays of the dorsal
fin, the second below the posterior rays of the dorsal
fin and slightly posterior, the third below the adipose
fin and slightly anterior, and the fourth at the end
of the caudal peduncle.
Care & Compatibility
They like their own territory
in the aquarium as males will sometimes spar with
other males, but usually nothing comes of this confrontation
as long as they have their own caves, be it PVC pipes,
ceramic pots or even under flat stones that have been
built up on the substrate.
Not easy. Good
water quality and water changing at the right time.
They lay their eggs in caves (pipes) and the male
guards them for about 10 days. The feeding of courgette
(zucchini) and peas taken out of their shell seems
to be a precondition for the successful spawning of
the Peckoltia genus.
The males have
short odontodes (spines) covering the front edge of
the pectoral fins and parts of the main body just
behind the gill plates, these spines run the full
length of the body, they also produce them on the
hard rays of the caudal fin. The females are devoid
of this character and I find that they are not quite
as colourful as the males, being that bit darker.
Omnivore; Vegetarian food,
tablets & pellets, insect larvae, zooplankton
and soft wood. As mentioned in the breeding section
they love courgette (zucchini), half cook them, sliced,
in a pot of water and then frozen for future use.
They are also partial to peas now and again. I find
they are not a great algae eater like their Chatasoma
cousins. I feed also algae wafers and tablet food,
they are also keen on frozen bloodworm. Not a hard
species to feed as again they are not too fussy.
fin: Fleshy finlike projection without rays,
behind the rayed dorsal fin. Caudal fin: The tail. Caudal peduncle: The narrow part of
a fish's body to which the caudal or tail fin is attached.
Dorsal fin: The primary rayed fin(s)
on top of the body. Pectoral fin: The paired fins just
behind the head. Supraoccipital: Unpaired bone at the
back of the skull, usually with a crest.
