Similar to Brochis ephippifer but this species has a clear caudal fin wheras Hoplisoma melanistium has small spots, a higher body shape and a shorter snout and a differnt lineage. 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 melanistius has now been placed in Lineage 9 and has the new genus name of Hoplisoma and a change to the specific name to melanistium. 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 melanistium: From the Greek melan = 'black' and histion = 'sail', alluding to the dorsal fin. Remarks: This species is still found on some online sources as Corydoras melanistius.
