n old favourite in the
hobby and a species that has been bred numerous times.
Males have more colourful markings than the females
and also have three black bands in the dorsal fin.
The first image shows the male of the genus and the
second shows a pair with the male to the front.
elegans - male
There are a few
different forms of this species and one of them was
described by Holly in 1940 as Corydoras pestai.
This is now a synonym of C. elegans but there
is a train of thought that this species (C. pestai)
may be valid and has been treated as so in Isbrücker
(2001b: 232). The list of other imported species still
to be described are C041,
elegans - pair male to front
In July 2000 I,
along with other U. K. catfish enthusiasts,
to Peru and fished the the Amazon River tributaries
including the Orosa River. Corydoras elegans
was the first species that I netted in the Tunche
Cano stream and so this species holds a special
place in my heart as the excitement at catching wild
Corydoras still lives with me to this day.

Wild caught specimens
The above images
show one of the catchment areas that we found C.
elegans and also showing the species 12 years
later on in 2012. I did not manage to breed this
wild stock but they have proved to be very long
living. I did breed this species many years before
which you can read about here in this article.
placed in Lineage 5 and a revision in the future
could involve the resurrection of the genus name
Gastrodermus (Cope, 1878).
Amazon River basin..Type
locality: Teffé, Brazil.
Male: 5.0cm (2ins) Female:
Short and compact. Dorsal1/7;
Anal fin; 1/6-7; 21-22 bony scutes in the upper lateral
series, 20 in the lower.
Ground colour yellowish,
upperside darker approaching to pale ochre. Underside
paler, white apart from the lateral scutes. Upper
surface of head marbled with grey- brown. A dark,
vague-edged, wedge-shaped band extends from the
hinder part of the head to the caudal peduncle,
its anterior portion passing through several blotches.
Below this band is accompanied along the flanks
by a pale stripe which, in turn, has a row of dark
spots along its lower edge. Gill cover is a brilliant
pale blue. Fins grey. A mottled and spotted pattern
exists in the head area. Males are more ornately
patterned and have also reticulated bands on the
dorsal fin, while the dorsal of the female is usually
Care & Compatibility
This is akin to most of this
genus, very peaceful, and would be best housed with
small to medium sized tankmates such as Tetras, Rasboras
and Danios or in a species tank for breeding purposes.
Best to purchase 6 individuals or more as they will
be happier in a group.
Bred many times
in the hobby and they spawn in the same Corydoras
pattern which you can read about here.
Males are more ornately patterned
and have also reticulated bands on the dorsal fin, while
the dorsal of the female is usually clear.
Readily accepts a mixed and
varied diet which includes granular foods, tablet
food, frozen bloodworm and a good quality flake.

the tail. Adipose fin: Fleshy finlike projection
without rays, behind the rayed dorsal fin. Scutes: Bony covering.
