septentrionalis is rather rare in the trade. It occurs in Venezuela and
Colombia. The species is very similar to Corydoras ellisae from
Paraguay. It differs from C. ellisae mainly due to the much longer snout
and the colourless fin (with a spotted pattern in C. ellisae).
were a bit surprised to obtain that particular species from Indonesia
now. There are so many species in Corydoras… But two features are very
special in C. septentrionalis. First: there is a very nice metallic
green shine on the body when the light falls in the right way. And
twice: we hardly ever observed a species of Corydoras so far that has
such a fascinating behaviour. When the males compete with each other or
when the winner of the competition courts before the female this
proceeding is so fast that the eye can hardly follow.
