Relevant Information:

Similar looking to C. saramaccensis and C. cervinus. 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 oxyrhynchus 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 oxyrhynchus: From the Greek oxys = 'sharp' or 'acute' and rhynchos = 'snout', alluding to the long snout.

IUCN Red List

Even though there are no available data on the population status and trend, the species is known from multiple records in Suriname. It is plausible to assume that the species may occur in other localities within the currently known distribution range. Considering this and the fact that there are no known threats to the species as whole, Corydoras oxyrhynchus is assessed as Least Concern (LC), (IUCN 2023).
