Bronze Corydoras Fish Origin:

The Bronze Corydoras Fish originates from South America. They are bottom-dwellers found in the Amazon and Paraguay River basins, where they roam sandy river bottoms living amongst submerged tree roots.

Bronze Corydoras Fish Size:

When full grown, these fish generally measure between 2 to 3 inches (5 – 7 cm) in length. Females are slightly larger than males at this stage of maturity. Like most catfish, their growth rate slows down as they age.

Bronze Corydoras Fish Colors and Markings:

This fish is identified by its dark gray or black body with three lighter colored bands running vertically along its sides starting just behind the gill cover up to the top third of the fish. The dorsal fin is yellow-brown with a dark edge. The caudal and pectoral fins are transparent with rows of brown spots running along them.

Bronze Corydoras Fish Tankmates:

As community fish, they can be housed with non-aggressive tank mates that don’t nip at their fins or disturb their natural habitat. Larger tank mates are often too big for these smaller catfish to bother anyway, but watch out for any small type of tetras as they will most likely be on this catfish’s menu if they are left in the aquarium together. Most loaches would also make good choices as companions since there is little chance of them being seen as potential food items by the corys.

Bronze Corydoras Fish Care:

The care requirements for the Bronze Corydoras are very similar to most other species of corydoras, though they have a slightly higher tolerance for salt in their water when compared with other breeds. They do best in well planted aquariums, but these fish will appreciate having some driftwood or rocks to add structure to their habitat. Be sure that all décor is smooth and without sharp edges that could damage their delicate barbels which could lead to infection if they become damaged.

They can be fed a varied diet of sinking dried foods supplemented with regular feedings of live brine shrimp and bloodworms, or a high quality flake food in small amounts three times a day. Just be sure that whatever food you choose is fresh to prevent any bacteria or parasites from harming your fish.

Bronze Corydoras Fish Lifespan:

On average this fish has a lifespan of 5 years, but can live up to 10 years if cared for properly and kept in good health. The average life expectancy of these fish is very similar to other variations of corydoras catfish with proper care techniques being the most important factor in their longevity.

Bronze Corydoras Fish Diet and Feeding:

As opportunistic feeders they will eat almost anything offered, but like most bottom feeders, plant matter should make up the bulk of their diet along with worms, insects (caterpillars, mosquito larvae, etc.) and small crustaceans. They will also eat some mollusks and smaller fish if they are allowed to scavenge in areas where these can be found.

Bronze Corydoras Fish Gender Differences:

As with most species of corydoras catfish there are no visible differences between the genders until they are ready to breed at which time the female is noticeably larger than the male.

Bronze Corydoras Fish Breeding:

Breeding this particular type of corydoras catfish is generally easy once a breeding pair has been established since they produce large amounts of eggs that become free swimming fry within 3 days after being laid by their mother who then protects them for an additional 4 or 5 days until they are large enough to survive on their own. They will need live foods during the first few weeks after birth in order for them to receive optimum nutrition at which time they can be fed finely crushed flake food soaked in vitamin enriched brine shrimp nauplii.

Conclusion:

This is one of the smallest species of corydoras catfish, but make great additions to any community aquarium due to their peaceful nature and active swimming habits which makes for excellent viewing entertainment within an aquarium environment. This fish has a moderate difficulty rating due its fin nipping tendencies when kept with tank mates that have long flowing fins. Even with this slight drawback though this fish still receives an average rating of 2 out of 5 for its ease of maintenance and ability to adapt well to aquarium life.
