Corydoras zawadzkii is so far known only from two tributaries to the rio Aripuanã and its conservation status is uncertain based on the currently available data of its geographic distribution. Despite that, no imminent threats to the species were detected in the area, and considering that it occurs in a protected area (Reserva Extrativista Guariba Roosevelt), Corydoras zawadzkii would be classified as Least Concern (LC) according to the International Union for Conservation of Nature (IUCN) categories and criteria (IUCN Standards and Petitions Subcommittee, 2014) (Tencatt & Ohara, 2016). Lineage: Placed in Lineage 1. When there is a revision they will stay as Corydoras (Lacépède, 1803) with the type species of C. geoffroy La Cépède, 1803. 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: Corydoras zawadzkii is named in honour of Dr. Cláudio Henrique Zawadzki, professor at the Universidade Estadual de Maringá (UEM), for his comprehensive contributions to the knowledge of Neotropical ichthyofauna, especially of the Loricariidae. Cláudio is a dear friend that directly participates in the professional formation of the first author. Treated as a genitive. (Tencatt & Ohara, 2016).
