Placed in Lineage 6 which has always been classified
as Corydoras (Lacépède, 1803)
so a new genus would need to be described and a new
type species when a new revision is carried out.
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: As this species
is found in the southern most parts of South America
it would need cooler water temperatures over longer
periods. Etymology: The specific
epithet refers to and is dedicated to Roberto Petracini,
Argentine fishkeeper, who for decades has been contributing
to the development and knowledge of Argentinean and
South (and Central) American fishkeeping.
