Lineage:
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. 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. Remarks:As this species is found in the southern
most parts of South America it would need cooler water
temperatures over longer periods.
