The third thumbnail specimen was caught by Memin who lives in a village in the jungle just outside of Leticia on the Brazil/Colombia border and catches fish for the exporters in that area. It has an unusual colouring but this species is highly variable in its markings. Lineage: Placed in Lineage 1, 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 pastazensis 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 pastazensis: From the Rio Pastaza.
