Relevant Information:

Similar to H. trilineatum from the same catchment area. So much so that there is a belief in some quarters that they are one and the same species (C. acrense is C. trilineatum) due to only one specimen (the holotype) being described. 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 acrensis has now been placed in Lineage 9 and has the new genus name of Hoplisoma and a change to the specific name to acrense. Aquarium Care: A tank setup would entail a soft substrate such as sand or a small gravel and a nice plant covering around the back and sides of the aquarium. If housed in a community tank a mixture of small South American characins or the smaller varieties of Asian Rasboras would suffice, as larger fishes would intimidate these shy Hoplisoma's, and would stop them eating and would be therefore detrimental to their overall health. Diet: A good quality flake food and tablet food for adults with sparodic feedings of frozen or live food will keep your Corydoras/Hoplisoma in good health. Etymology: The specific name acrense: from Acre, the state in Brazil where the species was found and L. -ense, denoting place, locality, country. Remarks: This species is still found on some online sources as Corydoras acrensis.
