Bronze Corydoras

As members of the armored Catfish family, Bronze Corydoras have tough skin and spines in the leading rays of their pectoral fins. These fish were one of the first species of Corydoras to be introduced into the aquarium trade and they remain a popular species today. Bronze Corydoras are widely distributed, having been found throughout South America in Columbia, Guyana, Venezuela, Peru and Bolivia as well as other countries. These fish tend to inhabit slow, shallow waters with muddy substrate. These fish are unique in that they are able to absorb air through the walls of their intestines as well as through their gills. Bronze Corydoras can be seen gulping air at the water surface on occasion, particularly in water with a low oxygen content. This species typically exhibits pinkish or yellowish coloration on the body with a white belly and a blue/gray hue covering the head and back. Sometimes called the Green Corydoras, these fish may also exhibit a greenish hue on the upper parts of the body.

Tank Set-up

Bronze Corydoras prefer tanks decorated with sandy substrate because gravel substrates may damage their sensitive barbels -- these fish also like to root around in the sand looking for bits of food. This species will also enjoy a tank that includes plenty of rocks and pieces of bogwod to provide cover. Because these fish can be found in a variety of natural environments, the level of flow in the tank is not important, but high-quality  filtration should still be utilized to keep the water quality in the tank high.


Bronze Corydoras are not fussy eaters - they are likely to accept any foods offered. To keep your Corydoras healthy, offer them a varied diet of sinking dried foods along with live and frozen foods such as brine shrimp and bloodworms. Supplement this diet with Spirunlina wafers and blanched vegetables to provide for the nutritional needs of these fish in regard to vegetable matter.


Breeding these fish is not difficult and they tend to breed readily in the community tank. To encourage spawning, condition the fish with live foods and perform large, cool water changes over a period of several days. These fish typically deposit their eggs on broad-leaved plants or tank walls and the eggs generally hatch after three days. Though corydoras tend not to eat their own young, it may be easier to raise the fry if you remove the adults from the tank following spawning.
