his 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 harm
was listed for many years as Ancistrinae sp. (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.
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 coloured background.
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
lujani aka L127/L207.
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 in general.
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.
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.
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
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.
Unpaired bone at the back of the skull, usually with a crest.
Dorsal fin: The primary rayed fin(s) on
top of the body.
Caudal fin: The tail.
Caudal peduncle: The narrow part of a fish's
body to which the caudal or tail fin is attached.
Pectoral fin: The paired fins just behind
Adipose fin: Fleshy finlike projection
without rays, behind the rayed dorsal fin.
Named for Snr. Gustavo Peckolt of

In honour of Dr. Nathan Lujan.
