Relevant Information:

One of the more prettier species of Corydoras with a metallic green body and yellow fins. Lineage: Placed in Lineage 7 alongside other members of the so called "aeneus group" with the designated type species: C. eques. A revision in the future would constitute the resurrection of the genus name Osteogaster. As of the latest update Corydoras melanotaenia has now been placed in Lineage 7 and has the new genus name of Osteogaster (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/Osteogaster in good health. Etymology: The specific name melanotaenia: mélanos, genitive of mélas, black; taenia, from tainía, band or ribbon, referring to the broad blackish lateral band. Remarks: Still found on some online sources as Corydoras melanotaenia.
