The species originates from the upper Rio Negro and never came frequently to Europe, mostly as by-catch to Corydoras schwartzi and C. incolicana. The exporters called him C. “Perreira II”. Why the species is so rarely caught is unknown. It can be bred quite well, but never in large numbers, so that usually the offspring go directly from aquarist to aquarist and never appear in the general trade.

These animals are still scientifically undescribed and were given the code number CW127 by Ian Fuller. It is the round snouted sibling species of the Corydoras bifasciatus from the same area, a long snouted species that is currently not available in significant numbers in the hobby.
