There seems to be two forms of this species, the other going under the trade name of Corydoras 'Dorsalis' which comes from the Rio Abunã, Brazil and has been given the Corydoras World number of CW086. C. armatus (now Hoplisoma armatum) is not very common in the hobby. Lineage: Placed in Lineage 9, the "short-snouted" species with the designated type species: C. punctatus. A revision in the future would constitute the resurrection of the genus name Hoplisoma (Agassiz, 1846). As of the latest revision (Dias et al 2024) Corydoras armatus has now been placed in Lineage 9 and has the new genus name of Hoplisoma and also a change to the specific name to armatum. 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 armatum: latin for armed with a weapon, referring to the finely serrated dorsal-fin spine, as high as the body, and stronger (but shorter) pectoral-fin spine. Remarks: This species is still found on some online sources as Corydoras armatus.
