New Corydoras from Peru

27. September 2012

Corydoras sp. C91, male Corydoras sp. C91, female

The pretty Corydoras sp. C91 is already a well known aquarium fish, although it is available only occasionally and very rarely. This species is a typical shortnose or roundnose Cory, which can be kept in the very same way as the common species Corydoras julii or C. trilineatus. The latter represent without any doubt the closest relatives of C91.

For the first time ever we were able now to import also the long snouted species that has the very same pattern as C91. Sadly we have no information where the fish have been collected. C91 is said to originate from the Rio Huallaga, which is an approx. 1.100 km long tributary of the Maranon, the larger of the two headstreams of the Amazon river. The longsnouted species imitating C91is a very attractive fish, that resembles much to Corydoras leopardus. However, the new species has a much more contrasting pattern in the caudal fin.

From the Rio Madre de Dios originates the saddle noses species C115/116. The Madre de Dios is also about 1.100 km long and is the largest tributary of the Rio Madeira. The Madre de Dios flows between the countries Bolivia and Peru. C115/116 also resembles much in C91, at least some specimens. For C115/116 has a very variable coloration, which is the reason that initially it was thought that it represents two different species. However, breeding the fish showed clearly that it is only one variable species (please see also Now we received for the first time ever very nice wild collected specimens that show the complete number of varieties: animals with and without lateral stripe and animals with or without a shoulder spot.

Keeping all these new Corydoras is easy, but one should keep in mind that only C91 and the long snouted species are schooling fish in the closer sense, while the saddle nosed types rather prefer to live individually or in small groups.
