Relevant Information:

There are three similar looking species. Hoplisoma sp. (C134) from Est. Amapá, Río Oiapoque in Brazil, Hoplisoma sp. (C040) from Rondônia, Brazil and Hoplisoma sp. (C073) also from Rondônia, Brazil. 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 griseus has now been placed in Lineage 9 and has the new genus name of Hoplisoma and a change to the specific name to griseum. 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 griseum: Medieval Latin for grey, referring to its uniform greyish colour pattern. Remarks: This species is still found on some online sources as Corydoras griseus.
