Relevant Information:

Very similar to O. zygata which has a slimmer profile. The fry of each of these two has proven that they are two seperate Corydoras/Osteogaster species. (Fuller, 1980) This unique pattern in the fry can be seen on the 5th and 6th thumbnail by image contributor and breeder, Graham Ramsay. Lineage: Placed in Lineage 7 alongside other members of the so called "aenea/us 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 rabauti 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 sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. 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 rabauti: Named in honour of the American collector Auguste Rabaut. Remarks: Still found on some online sources as Corydoras rabauti.
