Relevant Information:

This species was formerly split into two subspecies, this one which was C. blochi blochi and the other, C. blochi vittatus, which is now a species in its own right as C. vittatus. It was also cataloged in the C-number system as C032. Lineage: Placed in Lineage 1 the "saddle-nosed" species and when there is a revision they will stay as Corydoras (Lacépède, 1803) with the type species of C. geoffroy La Cépède, 1803. As of the latest update (Dias et al 2024), Corydoras blochi has been placed in Lineage 1 and has retained the genus name of Corydoras. Aquarium Care: As this is one of the longer snouted species it will be well suited to most community tanks. A well planted tank with a soft substrate such as sand so they can bury their snouts while searching out food. 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 blochi: In honour of Marcus E. Bloch, German physician and ichthyologist, (1723-1799). In 1794 he described Cataphractus punctatus which is now Corydoras punctatus (updated 2024 as Hoplisoma punctatum) , the type species of the genus Corydoras. Remarks: C032, C149 and CW059 are colour forms of C. blochi.
