These are the lists of the sizes, which both mail and female Corydoras species would be expected to reach under aquarium conditions. With 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. To avoid any confusion with the fact that there are 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.
