Skunk Corydoras

Also called the Arched Cory, the Skunk Corydoras is named for the black stripe running down its back. This stripe is superimposed on a silver or transparent body and the fins of this species are transparent as well. Skunk Corydoras are one of the more popular species of Corydoras in the aquarium hobby, largely due to their attractive appearance. These fish are also very peaceful in nature which makes them popular additions to the community tank. Though they will likely thrive with a variety of tank mates, Skunk Corydoras are best kept in groups with six or more of their own species and tend to become more active in the presence of conspecifics.

Tank Set-up

This species is native to the upper Amazon River basin and can be found in parts of Ecuador, Columbia, Brazil and Peru. These fish tend to inhabit rivers and tributaries and prefer a tank that mimics these conditions. The ideal tank for Skunk Corydoras would be decorated with sandy substrate and driftwood roots or branches. These fish also enjoy the addition of leaf litter which will stain the water with tannins, making it more acidic.


Skunk Corydoras are omnivorous by nature and are fairly easy to feed in the home aquarium. Offer these Corydoras a high-quality sinking pellet or wafer for a staple diet, supplementing it with small live and frozen foods such as bloodworms, Artemia and Daphnia. These fish may also accept Spirulina wafers or pellets.


Breeding Skunk Corydoras can be easily achieved in the home aquarium and it is best accomplished when the fish have been conditioned on live foods in groups with two males for every female. These fish prefer a breeding tank kept around 75 degrees Fahrenheit with a pH of 7.0, though large cool water changes may help to encourage spawning. Following spawning, the adults of the species should be removed from the tank because they will exhibit no parental care and may eat their own eggs.
