This was the first unidentified
(at the time) Corydoras to be given a C-number
(C001) in 1993 by the DATZ magazine. It is variable
in its markings and colouration but always carries
a blotch at the base of the dorsal fin. The last three
images show a variant from the normal colour pattern.
Named after the river where it was found, the Rio
Icana. 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. Aquarium
care: This is akin to most of this genus,
very peaceful, and would be best housed with small
to medium tank mates such as Tetras, Rasboras and
Danios or in a species tank for breeding purposes.
Diet: A good quality flake food and
tablet food for adults with sporadic feedings of frozen
or live food will keep your Corydoras in
Brazil; Rio Içana, Upper Rio Negro.
