he 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.
seussi belongs to
the family Callichthyidae from Brazil; namely the
Rio Poranga a tributary of the upper Rio Negro and
the Mamore River basin.
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.
is placed in Lineage 8 sub clade 4 which comprises
the "intermediate long-snouts" with deeper
bodies. It also includes Brochis in sub-clade
1 which was synonymised with Corydoras by
Britto in 2003 but in time there will be a revision
which will resurrect Brochis (Cope, 1871)
to full genera again.
Brazil; Mamoré River basin.
Male: 6.5cm (2½ins)
Female: 7.0cm (2¾ins)
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.
Care & Compatibility
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
The 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
Corydoras:Cory = helmeted;doras = leathery skin,(helmeted
Doras) cuirass. seussi: This catfish was
specifically named after (dedicated to) Mr.Werner
Seuss who is a well known German aquarist and author.
Dorsolateral:Refers to the area above the lateral line and
below the dorsal fin. Ventrolateral: Refers to the area below
the lateral line and above the ventral fins.
