Bronze Cory

The Bronze Cory is a sociable bottom-dwelling catfish with a bronze-to-olive body and a metallic green sheen. A group adds steady movement to the lower part of a planted community aquarium as the fish explore together and sift through the substrate.

Aquarium setup and care

Provide smooth sand or clean, rounded fine gravel, with plants or wood around the edges and open areas for foraging. Use reliable filtration and leave clear access to the surface for occasional air gulps.

Keep ammonia and nitrite at zero, perform regular partial water changes, and remove uneaten food. Corys require their own balanced diet; leftover food and algae are not sufficient.

Diet and feeding

Feed a complete sinking catfish pellet or tablet, supplemented with small frozen foods such as brine shrimp, daphnia, or bloodworms. Spread food across more than one spot so shy individuals receive a share.

Compatibility

Suitable companions include peaceful tetras, rasboras, and other small community fish with matching water needs. Avoid large predators and aggressive bottom dwellers. Corys need companions of their own kind even when other fish are present.

This is the bronze color form; color intensity varies with lighting, maturity, and the individual fish.
