Hoplisoma sterbai is sometimes confused with Brochis haraldshultzi. The difference being that H. sterbai has for simplistic reasons a dark basic body colour with white spots on the head and snout area, while B. haraldshultzi has it in reverse, a light body with dark spots/ reticulations. 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 sterbai has now been placed in Lineage 9 and has the new genus name of Hoplisoma. Aquarium Care: Corydoras sterbai is much like any other species of the genus Corydoras, easy to keep but will do better in a group as they are sociable animals and do like their own company. They will also appreciate a bit of water movement in the aquarium. Like most of this genus they are 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. Remarks: There is now a man made albino varierty of Hoplisoma sterbai as can be seen in the thumbnail gallery. Note the orange pectoral spines. This species is still found on some online sources as Corydoras sterbai.
