Relevant Information:

The second thumbnail image is of specimens collected by the image contributor the webmaster of Planet Catfish, Julian Dignall, near the type locality. The overriding identification is the black markings to the caudal peduncle and the very blunt nose. The Holotype is in the CAS, standard length, 30.5mm Venezuela, Rio Atabapo. 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 osteocarus has now been placed in Lineage 9 and has the new genus name of Hoplisoma and a change to the specific name to osteocarum. 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/Hoplisoma in good health. Remarks: Still found on some online sources as Corydoras osteocarus or Hoplisoma osteocarus..
