Relevant Information:

The feature for which C121 is known, the brown patch behind the gill cover, does not appear until the fish are around 4 months old and about 3cm in size. 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 sp. (C121) has now been placed in Lineage 9 and has the new genus name of Hoplisoma. 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 food. Remarks: This species could be a population of Hoplisoma burgessi which shows this unique gill pattern. This species is still found on some online sources as Corydoras sp. (C121).
