The Bronze Cory Catfish (Corydoras aeneus), commonly called the Bronze Cory or Green Cory, is a peaceful and hardy freshwater bottom-dwelling catfish known for its bronze-green metallic coloration and active social behavior. Best kept in groups of 6 or more, Bronze Corys are excellent for planted and peaceful community aquariums with soft substrate, clean water, and plenty of bottom space to explore.
The Bronze Cory Catfish (Corydoras aeneus) is one of the most recognizable and widely kept Cory catfish in the freshwater aquarium hobby. Its subtle bronze, olive-green, and metallic coloration may appear different depending on aquarium lighting, giving this classic Cory a surprisingly attractive appearance.
Also known as the Bronze Cory, Bronze Corydoras, or Green Cory, this species is valued for its peaceful personality, active bottom-dwelling behavior, and ability to adapt to a range of properly maintained freshwater aquariums.
Taxonomy note: This species has traditionally been known throughout the aquarium trade as Corydoras aeneus. Under newer scientific classification, the accepted combination is Osteogaster aenea. Both names refer to the fish commonly sold as the Bronze Cory Catfish.

What Does a Bronze Cory Catfish Look Like?
The Bronze Cory Catfish typically has a pale cream-to-pink underside with bronze, olive, gray, and metallic green coloration across the upper body. Depending on aquarium lighting and viewing angle, the sides may display an attractive greenish or blue-green sheen.
Like other Cory-type catfish, Bronze Corys have a compact armored body covered with protective bony plates instead of traditional fish scales. Sensitive barbels around the mouth help them explore the substrate while searching for food.
Their understated metallic coloration, rounded body, and constantly moving barbels give Corydoras aeneus the classic Cory catfish appearance loved by freshwater fish keepers.
Bronze Cory Behavior & Group Size
Bronze Corys are peaceful, social bottom-dwelling fish that should not be kept alone. We recommend maintaining a group of at least 6 Bronze Cory Catfish.
In a proper group, they can often be seen exploring the aquarium floor together, searching through the substrate for food, resting near one another, and interacting with other members of their school.
Larger groups may display even more natural and confident behavior when aquarium space and filtration allow.
Bronze Corys may occasionally make a quick trip from the bottom of the aquarium to the water surface before returning to the substrate. Cory catfish are capable of taking atmospheric air, so occasional surface visits are a normal part of their natural behavior.
Ideal Aquarium Setup for Bronze Corydoras
A 20-gallon or larger freshwater aquarium provides a good starting point for a group of Bronze Cory Catfish. Because they spend much of their time exploring the aquarium floor, usable horizontal bottom space is particularly important.
A soft sand substrate or smooth fine gravel is recommended. Bronze Corys regularly search through the substrate with their sensitive barbels, so sharp or abrasive materials should be avoided.
Plants, driftwood, smooth rocks, leaf litter, and shaded resting areas can create a natural-looking environment while leaving open sections of substrate for the group to explore and forage.
Bronze Cory Water Parameters
Bronze Cory Catfish generally do well at temperatures around 70–81°F (21–27°C) with a pH of approximately 6.0–8.0.
Their ability to adapt to a relatively broad range of freshwater conditions is one reason Corydoras aeneus has remained such a popular aquarium fish. However, stable water quality is still much more important than constantly adjusting the aquarium to reach an exact number.
Always introduce Bronze Corys to a fully cycled aquarium with appropriate filtration and regular maintenance. Ammonia and nitrite should remain at zero, and sudden changes in temperature or water chemistry should be avoided.
What Do Bronze Cory Catfish Eat?
Bronze Corys are omnivores and should receive a varied diet formulated for bottom-dwelling fish. Quality sinking pellets, tablets, or wafers can form the foundation of their aquarium diet.
Their diet can also be supplemented with appropriately sized frozen or live foods such as brine shrimp, daphnia, bloodworms, and similar nutritious foods.
Bronze Cory Tank Mates
The peaceful temperament of the Bronze Cory Catfish makes it suitable for a wide variety of freshwater community aquariums. Tank mates should be non-aggressive and comfortable within similar water conditions.
Potential tank mates may include peaceful tetras, rasboras, guppies, peaceful gouramis, compatible dwarf cichlids, other suitable Cory catfish, and many other peaceful freshwater community species.
Avoid large predatory fish and aggressive tank mates that may chase, injure, or prevent the Bronze Corys from feeding comfortably.
