Relevant Information:

This species was given the CW-number (Corydoras World) of 36 as it had not previously been given a C-number. It is now been proven that CW036, is the true Corydoras arcuatus instead of the shorter nosed C020 due to the work carried out by U.K. aquarist Steven Grant in 2014. Lineage: Placed in Lineage 8 sub clade 4 which comprises the "intermediate long-snouts" with deeper bodies. It also includes Brochis in sub-clade 1 which was synonymised with Corydoras by Britto in 2003 but in time there will be a revision which will resurrect Brochis (Cope, 1871) to full genera again. As of the latest update Corydoras arcuatus has now been placed in Lineage 8 sub clade 4 and has the new genus name of Brochis (2024). 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 arcuata: arched, like a bow, (referring to the stripe). Remarks: Still found on some online sources as Corydoras arcuatus.
