Coyrdoras paleatus wild

16. July 2021

Only very rarely we receive wild collected Corydoras paleatus. Imports of this species, which is widespread in southern South America, didn´t appear for more than 10 years, because many export stations in southern Brazil had to close down when some of the most important ornamental fishes of the region were forgotten on the Brazilian positive list, which regulated which species could be caught and exported as ornamental fish. Now a negative list is in effect, meaning that all species may again be caught and exported unless they are specially protected.

This veteran among the aquarium fishes was already bred in 1878 by the Parisian aquarium pioneer Pierre Carbonnier, outside France the species is available since 1893. Since then there have always been offspring and also various breeding forms (long-finned, albino etc.) are always available in the trade. 

For our customers: the wild caught species have code 239553 (lg) and 239554 (xlg) on our stocklist. Please note that we only supply wholesale.

Corydoras longipinnis

12. February 2018

We were able to import an interesting Corydoras species from Paraguay, namely Corydoras longipinnis. This species has been scientifically described as recently as 2007 by Joachim Knaack. The new species is a close relative to the well known Corydoras paleatus and reminds one somewhat of the longfinned sport of that species. In Corydoras longipinnis only males develope long extended pectoral fins, whereas in the longfinned sport of C. paleatus also the females show that feature.

Corydoras longipinnis is a subtropical species and should therefore be kept at room temperature. For those who have the opportunity: it can be kept in garden ponds during summertime. Breeding C. longipinnis is easy and is the same as in C. paleatus. That means the fish must be fed heavily until the females show a swollen belly and then you have to change repeatingly a great amount of water and fill up with cool water (3-5°C cooler than the old water). This triggers mating and spawning.

Corydoras longipinnis should be kept in groups of at least 7 specimens. It is completely peaceful against congeneers and all other tankmates. The fish take readily any usual fishfood. Plants become not destroyed. The water parameters are of no great relevance. The pH should not be lower than 6 and not higher than 8.5.

A single bycatch is also very interesting. It is a specimen belonging to the species Corydoras ellisae. But while „regular“ C. ellisae show only two large blotches on a pale ground, this specimen imitates in a certain degree the pattern of C. longipinnis.

For our customers: Corydoras longipinnis has code 233552 on our stocklist. Please note that we exclusively supply the wholesale market.
