Relevant Information:

Known for many years erroneously as C. bolivianus, but in 1999 Isbrücker recognised that this species and C. geryi where one and the same. As they were described in the same paper he acted as first reviser and named C. bolivianus as a synonym of C. geryi. The males of this species are more ornately patterned than the females who are plainer. Not unlike Brochis pantanalensis from sub-clade 2 and can sometimes be mistaken for them but the caudal fin in C. pantanalensis is hyaline (clear). Lineage: Included in Lineage 8 (sub-clade 3) with the "intermediate long-snouts" with deeper bodies. As of the latest update Corydoras geryi has now been placed in Lineage 8 sub clade 3 and has the new genus name of Brochis (Dias et al 2024). Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium tank mates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. 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 geryi: In honour of French physician and ichthyologist Jacques Géry (1917–2007), for his many contributions to the ichthyology of the freshwater fishes of South America. Remarks: Still found on some online sources as Corydoras geryi.
