his large peaceful Loricariid
was described by C.H. Peters last century with a specimen
collected by the German collector Dr. C. Sachs in
Venezuela and included in a monthly report of the
Academy of Science in Berlin.
As stated the type locality
is Venezuela (Calabozo). Most of the specimens that
come into the hobby originate from Colombia from
Meta, near Villavicencio and it is not clear if
these fish are identical to the ones already mentioned
in the type locality in Venezuela. If there is an
uncertainty the name is usually given as Panaque
For its large attainable
size the "Royal Panaque"
is a peaceful Loricariid.
It can be territorial with
its own kind so better to house it on its own with
similar sized tankmates in a large aquaria.
When a youngster its colouration
with its stripes and spots is indeed wondrous to
behold but reaching adulthood it becomes more of
a dull grey/brownish colour.
The picture below shows the
spoon shaped teeth around the mouth which helps
it to scrape algae of material such as wood/roots
and the glass on the aquarium walls. The shape of
the teeth of course tell us that this is predominately
a vegetable loving catfish and the Diet
section table below will spell this out.
- showing the spoon shaped teeth
in mind that this fish will produce a lot of waste
due to its diet so will need a large external filter
which will turn the tank contents around about six
times in the hour and give it a good water flow.
A fully grown individual would need a 5 or 6ft tank
for it to function properly. You will need driftwood
or similar as this catfish likes to chew on it and
its long stage survival depends on this. It will
tend to hide during the day and come out at night
and actively search out food.
are a few similar species in the nigrolineatus-complex
which may or may not be the same species as they
come from different countries and river systems
in South America but in the main it is the Northern
half of South America that houses these very impressive
L190 is believed to be Panaque
as mentioned there needs to be more work carried
out on this and the other similar looking Panaques.
D. 1,7; A, 5; V, 1,5; Lat.l.
25-26. Short and heavy, the depth one-fifth less than
the width, which is about 3 in the length. Caudal
peduncle comparatively slender, its depth equal to
one-third of the greatest depth. Head large, its width
at the opercles about equal to the length of the snout
and orbit; profile rather straight from tip of snout
to the eye., the occipital strongly arched; a depression
above the eyes; a broad blunt ridge from the eye forward;
occipital bone truncate behind, margined by a single,
large nuchal plate; temporal shield forming the posterior
and half the upper margin of the orbit. Snout rather
pointed, entirely granular; the extreme sometimes
naked. Orbit 5 in the snout, 7½ in the head,
4 in the interorbital. Lower surface of the head granular;
lips with short thick papillae; teeth large, broad
tipped. Preopercle large, its bristles slender, the
longest varying from 1-2 diameters of the orbit in
length. Region between eye and gill opening entirely
granular. Humeral ridge obtuse; the lateral scutes
with short marginal spines which are largest and most
numerous on the tail and on the uppermost and lowermost
series. Ventral surface entirely granular. Distance
of the dorsal fin from tip of snout about 2 in the
length. Base of dorsal fin equals its distance from
the base of the middle caudal rays. Caudal obliquely
truncate, the central rays 2 in the head. Anal short,
placed under the interspace between the dorsal and
adipose fins. Ventrals inserted under the first dorsal
ray, reaching beyond base of anal. Pectoral fins reaching
beyond base of ventrals.
Dark brown, everywhere with
wavy longtitudinal lines of white; the fins all coloured
and striped like the body.
Care & Compatibility
Can be kept in a large community
tank with like sized tankmates such as Cichlids
and or Large Barbs who will
swim in the upper layers of the tank, even smaller
congeners will come to no harm from the "Royal
Pleco". Not a good
idea to house aggressive species in with your P.
they will tend to upset this peaceful catfish.
been bred in the aquarium but information is scarce.
The males develop very long
interopercular odontes and hooked spines on the anterior
pectoral fin spines.
Will feed/chew on driftwood
and need such in a tank. Vegetable
foods are a must for this herbivore such as
algae, cuccumber, courgette
(zucchini), lettuce, spinach and vegetable tablet
food. It will also take flake food but if you can
give it veg. flake, all the better. You can feed it
meaty foods such as the many varieties of frozen but
it is not a good idea to feed this too often as its
long digestive track is geared up for greens.
common name for plecostomus. Panaque nigrolineatus
was the first described and it is from central Venezuela. nigrolineatus:
Area between the skull and dorsal fin. Occipital: A
median bone on the upper surface of the back of the
head; pertaining to the occiput.
bony covering of the gills of fishes. Humeral: Bony
extension of the pectoral girdle. Truncate: Cut off, blunt. (as in squared
off caudal fin).
