Here we have divided the family Corydoradinae into there respective genera. Aspidoras, Brochis, Corydoras and Scleromystax. With more than one hundred and fifty Corydoras species the Catfish Study Group decided for the purpose of their annual shows, to divide the group into two sections. The division was made at 57 mm SL. To create two evenly balanced show classes and to avoid any confusion with the fact that there are generally size differences between males and females, it is the female sizes that determine which class the species is shown in. All size lists are reviewed annually and new entries and reassessments are added as they become known.
