This is a variable marked species with some specimens with or without the black blotch to the dorsal fin. Lineage: Placed it in Lineage 1. 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 acutus 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. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and a good quality flake. Etymology: The specific name acutus: pointed; a neadle or spine, referring to its pointed or sharp snout. Remarks: The C-numbers C077 and C109 are the same species.
