The Skunk Cory is omnivorous and will accept a wide variety of small live or prepared foods. Corydoras arcuatus should be given a balance of meats and veggies to maintain health and nutrition.


The males have a pointier, more pronounced dorsal fin while the females tend to be plumper and dull in coloration.


In preparation of breeding, the female will clean various locations throughout the aquarium. Once the eggs are fertilized, she places her eggs on her prepared surfaces. The parents should be removed from the breeding tank after all the eggs are placed. The eggs will hatch within 8 days and the fry can be fed fry powders or newly hatched brine shrimp.


Skunk cory has a lifespan of approximately 4 years.


The Skunk Cory can be found in rivers through out South American countries such as Peru, Brazil and Ecuador.

Short Description

This is one of the more sensitive species in the corydoras group. If the water conditions are poor the barbels on the Skunk Cory can become infected quite easily. Keep Corydoras arcuatus in groups of 6 or more, but be sure to provide plenty of hideouts to minimize stress. Do not add salt to an aquarium containing Skunk Corys because they cannot tolerate salinity.
