(Other members of the genus Corydoras)

ADULT SIZE: 7 cm

WATER CONDITIONS: Not critical

TEMPERATURE RANGE: 24-28 C

FOOD: Feed Corydoras aeneus small live-foods and fine grade dried foods

DISTRIBUTION: This species comes from Argentina, Bolivia, Brazil, Colombia, French Guiana, Guinea, Paraguay, Peru, Surinam, Venezuela

SEXUAL DIFFERENCES: Females of this species are larger and more rounded than males.

AQUARIUM CARE: Like all corycats, does best in a small shoal of six plus individuals. An easy species ideal for a well planted community. This species has a wide distribution in southern America, and will fit well into an Amazonian tanks with swordplants, leaflitter and sunken bogwood.

This catfish will eat most live and dry foods, but is particularly fond of worms and small crustaceans.

C. aeneus does fine in a peaceful community tank with small shoalers fish: tetras, danios, killifish etc. Aggressive fish, cichlids for example are problematic in all but the largest aquariums at spawning time.

BREEDING: Breeding is triggered by the start of the rainy season in the wild; a situation easily replicated in captivity by a large water change of slightly cooler water. Eggs are typically laid on stones, plants, and often the aquarium glass.

Other Comments: when you the males harassing the females do a partial water change and fill it with cooler water until the temperature is lowered from 72F to about 70F then start feeding them more often(small snacks throughout the day) of live or frozen bloodworms and catfish pellets. also remember to remove all the tankmates. my blue gourami and the corys ate the ones I didnt scrape off of the tank glass-and you have to be careful when you do that!
