Relevant Information:

Similar to Hoplisoma trilineatum but H. julii is a much daintier looking species with fine spots on the head whereas H. trilineatum has wavy lines on the snout and is a more robust looking species. Lineage: Both are 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 julii 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. Etymology: The specific name julii: patronym not identified, possibly Julius Michaelis, who provided Steindachner (and Günther) with fishes from Brazil. Remarks: This species is still found on some online sources as Corydoras julii.
