Minimum aquarium size: 76 L (20 gal)

Water: Freshwater 22 °C (72 °F) - 26 °C (79 °F)

Omnivore. Considered scavengers, these fishes are often neglected when it comes to feeding. They must be fed in the morning and just after the lights are extinguished at night to ensure optimum health and prepare them for spawning. Will accept a wide variety of meaty and herbivore aquarium fare, including flakes and pellets, especially those specifically designed for corys.

Aquarium Compatibility

Their constant grubbing keeps the substrate well stirred and free of stagnant pockets.


The larger female carries fertilized eggs between her ventral fins and deposits them on glass panes, leaves or stones. Fry are easily raised in a well-established tank with a layer of mulm.


The Bronze Corydoras is a schooling species that should be kept in groups of at least three to best observe their natural behaviors.

This species is sometimes confused with the Emerald Catfish Brochis splendens, another member of its subfamily.
