Relevant Information:

It is reported that there is an occurrence of different head shapes between some populations in this species, including sharp and rounded snouts. 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 negro 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: Named after the river of the same name.
