Relevant Information:

Similar looking to Hoplisoma paleatum but with a more colourful body pattern and also tends to be stockier. The gill covers have a metalic green sheen when in good condition. Lineage: Placed in Lineage 6 which has always been classified as Corydoras (Lacépède, 1803) so a new genus would need to be described and a new type species when a new revision is carried out. As of the latest revision (Dias et al 2024) Corydoras ehhardti 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 ehrhardti: Patronym not identified, possibly in honour of Wilhelm Ehrhardt (1860–ca. 1936), German animal collector and taxidermist, who supplied several museums with zoological specimens from Brazil, including presumably types of this catfish. Remarks: This species is still found on some online sources as Corydoras ehhardti.
