C. froehlichi (now Hoplisoma froehlichi) can be distinguished from its most similar congeners, Hoplisoma carlae, H. ehrhardti, H. longipinne and H. paleatum, by the absence of small plates on the ventral surface of the trunk (vs. presence); and by having markedly rounded snout (vs. relatively pointed snout). 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 revision is carried out. As of the latest revision (Dias et al 2024), Corydoras froehlichi 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 froehlichi: In honour and memory of Dr. Otávio Froehlich (1958-2015), UFMS (Universidade Federal de Mato Grosso do Sul), great teacher, and for generously sharing his knowledge with several colleagues, besides contributing to the development of LFCT as researcher and person. Remarks: Rare in imports. This species is still found on some online sources as Corydoras froehlichi.
