Was thought for many years that this species was Corydoras arcuatus, now Brochis arcuata, but after investigative work by English aquarist Steven Grant (2014) the original short nosed species that was supposed to be C. arcuatus (B. arcuata) has turned out to be a longer nosed species which had been given the CorydorasWorld number of CW036. 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 Hoplosopma (Agassiz, 1846). As of the latest revision (Dias et al 2024) Corydoras granti 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. Update 2019: C. granti is widely distributed throughout the central and western portions of the Amazon basin, being known from the rivers Negro, Caquetá, Putumayo, Juruá, Purus and Javari basins and direct tributaries of the Rio Amazonas-Solimôes in Brazil, Colombia, Ecuador and Peru. The record from the Iquitos region in Peru was based on unpreserved specimens Collected by Hans Evers (pers. comm.) Tencatt et al. Etymology: Hoplisoma granti is named after Steven Grant, aquarist and amateur ichthyologist who was the first to realise the distinctness of this species from the true C. arcuatus (Brochis arcuata). A genitive noun. Remarks: Still found on some online sources as Corydoras granti.
