The first 4 images are of specimens that were caught in a little creek in Corrientes province, about 400 km to the north of Paraná City Northern Argentina by the Image Contributor, Carlos H. Bishop. The last two thumbnails show the original form of O. aeneus from the Island of Trinidad kept and bred by the Image Contributor, Benny Hubel Hansen. 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 Cope, 1871. As of the latest update Corydoras aeneus has now been placed in Lineage 7 and has the new genus name of Osteogaster and a change to the specific name to aenea (Dias et al 2024). Aquarium Care: Will do well in a community setup with smaller tank mates such as Rasboras and Tetra's. Do not house with aggressive species or large Cichlids. Reproduction: Like to lay their eggs (300 or more) in the direct flow of a filter usually high up on the glass where the flow strikes. Eggs will hatch in 3 to 4 days and will use up their yolksac after 3 days. Diet: The fry after 3 days feed on infusoria then on to microworm, fry flake, then progress on to Brine Shrimp naupli. Adults can be fed the usual good quality flake food, frozen bloodworm, tablet foods, white and grindal worms. Etymology: The specific name aenea: meaning bronze. Remarks: There are a few different varieties over a wide distribution discovered since the original first species was captured in the island of Trinidad, this the type species of C. aeneus. All these these other varieties may be reclassified in the future. Still found on some online sources as Corydoras aeneus.
