The last month of 2006 brings another
factsheet from our resident "guru" Chris Ralph and
a look at a relatively new Cory which has only been in the hobby
for the last 10 years, and is coincidental in that ScotCat will
be celebrating 10 years next month also, so I will hand you
over to Chris to guide you along.
orydoras seussi has been available to the hobbyist
for a few years now, and shares a similar colour pattern with
gossei, which has a rounded snout.
Before being described scientifically as Corydoras seussi
this magnificent catfish was referred to as C27.
belongs to the family Callichthyidae from Brazil; namely the
Rio Poranga a tributary of the upper Rio Negro and the Mamore
Corydoras seussi prefer to be kept in water which has a
pH in the range of 6.5-7.2 (although it has been known for this
species to tolerate a much wider range of pH 6.0-8.0), and hardness
in the range of 2.0-25.0 dGH. This catfish is ideally suited
to temperatures in the range of 22-26ºC.
I would suggest a minimum size of 24”
x 15” X 12” for a shoal of these fascinating catfish.
The preferred substrate for keeping these catfish should be
good quality aquarium sand such as BD Aquarium Sand, or very
smooth rounded gravel in order to prevent their barbels from
being damaged. The aquarium should provide some shelter in the
form of rocks, bogwood and aquatic plants. As with all other
species of fish, water quality and general husbandry is very
important, and I would recommend that the aquarist undertake
a minimum of 25% water change on a fortnightly basis.
Typical triangular Corydoras body shape
with a pointed snout.
The base colour of the body is tan overlapped
by a much darker coloured pigment which is slate grey/blue. The
dorsolateral scutes are much darker exhibiting the slate grey/blue
colour than the ventrolateral scutes which are tan coloured. The
head region is overlaid with an orange to almost gold colour,
which in natural sunlight is truly magnificent. The head area
around the barbels and eyes is also overlaid with light coloured
spots. The first rays of the dorsal, pectoral and ventral fins
are orange in colour interspersed with some slate grey/blue colouration.
The soft rays of the pectoral and ventral fins are orange in colour,
whilst the remaining fins (dorsal, anal, adipose and caudal) are
light (white) coloured with slate grey to black coloured almost
stripy markings. The caudal fin has 5-6 distinct vertical black
bands/stripes. In bright sunlight there is a green sheen which
can be seen over the top half of the body of this catfish.
These catfish are very peaceful towards
their own kind and indeed other species of Corydoras.
These catfish are ideally suited to being kept in a community
aquarium environment with other non-aggressive species of fish
such as tetras and dwarf cichlids. Whilst Corydoras seussi
are not cheap to purchase, wherever possible I would recommend
that you purchase a minimum of six specimens, as they are naturally
found in the wild in large shoals.
Whilst this is a species of Corydoras
that I am fortunate to have kept in recent years I was unable
to persuade the fish to breed. Whilst there are documented records
for spawning the similar coloured Corydoras gossei,
I am not personally aware of any successful accounts for spawning
Corydoras seussi to date. I would however, envisage
that when breeding these catfish would adopt the typical Corydoras
“T” clinch when mating, which involves the female
transferring sperm from the male to her eggs held in her ventral
fins prior to them being laid carefully on a chosen surface.
It is documented and observed that the female takes the sperm
from the male into her mouth which is then passed out of her
vent and on to the eggs which she holds in small numbers between
her ventral fins.
males tend to be slightly smaller and more slender than
the females. The dorsal and pectoral fins of the males
tend to be more pointed than those of the females. Sexing
of these catfish is easier when being viewed from above.
As with all the other Corydoras that
I have had the pleasure to keep over the years, Corydoras
seussi readily accepts a mixed and varied diet. I personally
feed all of my Corydoras on sinking pellets, good quality
flake foods, granular foods, cultured whiteworm and frozen foods
such as bloodworm to name but a few.
Cory = helmet, Doras
= skin. This catfish was specifically named after
(dedicated to) Mr.Werner Seuss who is a well known German
aquarist and author.
