This is the type species of the Corydoras genus. This species has also a third rictal barbel also found in C. amapaensis, C. septentrionalis and C. simulatus. Lineage: Placed 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. As of the latest update (Dias et al 2024), Corydoras geoffroy has been placed in Lineage 1 and has retained the genus name of Corydoras. 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. The males can be somewhat aggressive to each other so would need a large tank and hiding places to dilute this trait. 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 name geoffroy: In honour of colleague Étienne Geoffroy Saint-Hilaire (1772–1844), French naturalist, “who has earned the gratitude of all who cultivate natural history through his observations of the various animals of Egypt, particularly the fishes of the Nile” (translation) [a noun in apposition, without the patronymic “i”].
