his very impressive looking Loricariidae below is
owned by Andy Duck of the Northern Area Catfish Group
of Great Britain (now the Catfish
) It has won countless trophies including Supreme
Champion at the British Aquarist Festival. At the
time of this factsheet in 1997 it was of course known
as Pseudacanthicus leopardus but since 2001
there has appeared in the trade the true P. leopardus
described by Fowler in 1914 and the Loricariidae that
was formerly known as leopardus is now Pseudacanthicus
sp. L025. the Scarlet Pleco.
if you have taken in all that! I will point out the
differences in the both species.
In the original description it was noted that P.
leopardus had pale to dark brown and numerous
black blotches throughout the body as can be on the
fish below, this is where it gets its species name
from, Leopard-like (a reference to the colour), while
L025 above has four lines of spots running the length
of the body. The difference is quite significant with
also the eyes being somewhat dissimilar, L025 has
to me, 'evil eyes', which seem to follow you around
when viewing it, and they are also yellow. The eye's
of P. leopardus are normal and it is also a
smaller fish than Pseudacanthicus sp. L025
which grows to an impressive 40cm (16ins)
two short write-ups by U.S. aquarists Larry Vires
and Les Mumford. Several aquarists have had
problems with feeding the smaller fish on a flake
diet and had me stumped until I spoke with a local
shop which has 3 of them in their display tank. The
fish grow rather quickly if given a meaty diet of
live or frozen foods, but they could not get them
to accept flakes. Larry Vires.
also E-Mailed me about his leopardus which
he aquired from a friend returning from Brazil. It
is now 6" long and he tells me that it is quite
keen on zuchini (courgette).

(2010): According to Seidel (2008), L114/LDA07 is
a similar looking species from the Rio Demini in the
central Rio Negro system in Brazil. P. leopardus
is supposed to be more elongated and strongly flattened
and a different colouration than the L and LDA numbers
Acanthicus, Leopard Pleco, LDA073, L600
Type locality: Rupununi River, British Guiana
... in the highlands of British Guiana, approximately
secured in North Latitude 2º to 3º, and
West Longitude 50º20'.
Dorsal 1/8; Anal 1/5; Pectorals;
1/6; Ventrals 1/5; 24 bony scutes in a lateral series.
Dorsal fin large, flag-like. Head and gill cover thickly
set with spines; interopercular with 12 hooked spines
which are movable.
Pale to dark brown with numerous
orregular black blotches on the body and fins. Underside
Care & Compatibility
When small they can be kept in
a community tank but when adult, they can get quite
aggressive. A large aquarium (6' 0" or over)
is needed to display this dramatic looking Loricariid
to its best advantage. I do feel that this is a fish
only for the specialists who have the experience and
dedication to take care of it, and to take care of
the good water quality needed. Prefers soft and acidic
water as it is a black-water fish.
Reported to have
been bred in the aqurium but very high losses of fry.
Seem to preferr cooked mussels
and prawns as adults. Include some vegatable food
such as zuchini (courgette). Will also take frozen
bloodworm and tablet food.
