It is reported that there
is an occurrence of different head shapes between
some populations in this species, including sharp
and rounded snouts.
Placed it in Lineage 1, and when there is a revision
they will stay as Corydoras (Lacépède,
1803) with the type species of C. geoffroy
La Cépède, 1803. Aquarium Care:
As this is one of the longer snouted species it will
be well suited to most community tanks. A well planted
tank with a soft substrate such as sand so they can
bury their snouts while searching out food. Diet:
A good quality flake food and tablet food for adults
with sporadic feedings of frozen or live food will
keep your Corydoras in good health. Remarks:
The males can be somewhat aggressive to each other
so would need a large tank and hiding places to dilute
this trait. Remarks: Named after
the river of the same name.
