was one of the first Corydoras that I bred
in my early fishkeeping days and didn't realise it
until I spotted the fry darting about the tank. Try
to get a ratio of two males to one female, but if
not, a pair will do. Some varieties have dark flecks
on the edges of the bony scutes, while others are
devoid of this.
This species can
be confused with Corydoras
davidsandsi and C.
melini but the revealing
factor is the position of the black body stripe on
C. metae which runs over the ridge of the back
whereas in C. melini it breaks and divides
into two over the back and continues to almost the
end of the lower lobe of the caudal fin, in other
words it shows the body colouration on the ridge of
the back, while metae, on the ridge of the
back, is black.
between C. metae and C. davidsandsi
is that the latter has a broader black band which
covers the ridge of the back, whereas metae has a
thinner band and has also a thinner black band over
its eyes, compared to C. davidsandsi. The latter
has also a lighter body colour.

higher Ph and not too acidic would suit this species.

easy enough species to keep and while of no great
beauty it does have a pleasing colouration and pattern
that even the most discerning aquarist would find
appealing. It would probably make a good step-up for
the beginning Corydoras keeper from the easier
kept species of C.
In 2005 the book Identifying Corydoradinae Catfish
by Ian A. M. Fuller and Hans-Georg Evers (2005) was
published and at that time little was known about
the relationships among different species in the Callichthyidae
as a whole and even less was known about the relationships
among the Corydoradinae. This was changed in 2011
with the publication of the molecular phylogeny of
the group: Evolution, Ecology and Taxonomy
of the Corydoradinae revisited: Markos A
Alexandrou & Martin I Taylor (2011), which was
published in the follow up book in 2011, Identifying
Corydoradinae Catfish Supplement 1.
Corydoras metae is placed in
Lineage 9, the "short-snouted" species with
the designated type species: C. punctatus. A revision
in the future would constitute the resurrection of
the genus name Hoplosopma (Agassiz, 1846).
South America:Colombia, South America, in the Rio Metae where
the species inherited its name.
Male 4.5cm (1¾ins) Female:
Head short and compact.
Light brown beige. Colourless
and transparent dorsal fin with slightly more than
half colored black. This colouration can run to
the tip of the dorsal fin spine. The caudal fin
rays are banded brown and white. A black eye band
covers both eyes, bridging the top of the head.
Some dark striping does exist in the centre of the
body with the basic body colour showing through.
This gives a rib-like appearance.
Care & Compatibility
Good addition to an average
sized community tank. Purchase at least six specimens
to form a group.
