Bronze Longfin Corydoras 4.5cm

Long Finned Bronze Corydoras

For aquarists looking for an elegant, active, and durable bottom dweller, the Long Finned Bronze Corydoras is a fantastic choice. This strain is a selectively bred variation of the classic Bronze Corydoras, enhanced with flowing, extended fins that give it an extra level of visual appeal. These fish retain all the hardiness and social behaviour of their standard counterparts while offering a unique aesthetic that makes them stand out in any aquarium.

As their name suggests Long finned bronze Corydoras display a warm, metallic bronze body with golden-green iridescence, especially noticeable under proper lighting. Their most striking feature is their elongated, elegant fins, with the dorsal fin reaching a prominent height and the tail fin trailing gracefully behind them. Just like any other corydoras species the long fin bronze cories constantly stir the substrate layer in order to look for food. This behaviour ensures they are constantly keeping the substrate turned over and any debris in the water column, which can then be picked up by the aquarium filter. They are almost exclusively a bottom dwelling fish and are an awesome option to add some life to the bottom of the tank. These corydoras are not a shy fish either since they were born and brought up in captivity. They are constantly active, making them a great and popular fish for community and planted aquariums. These fish are also considered to be a schooling catfish, in the wild, standard bronze cories are often seen in groups of a few hundred however in the home aquarium it is recommended to keep at least 4 or more. An ideal school would be around 10 plus individuals to really make them feel comfortable and to add some activity to the tank.

Breeding long finned bronze corydoras is relatively easy, making them a great species for aquarists looking to try their hand at corydoras breeding. Males are generally slimmer and smaller, while females tend to be rounder and fuller-bodied when carrying eggs. They are egg scatterers, often laying their eggs on glass, plants, or decorations. A slight drop in temperature and increased feeding of high-protein foods can help trigger spawning behaviour.

Tank Recommendations for your Long-Finned Bronze Corydoras

As long-finned bronze corydoras reach around 6 cm as adults it is best to keep them in an aquarium with a minimum size of around 70 liters. A larger aquarium will always be better due to their active behaviour and it also allows for the space to keep other tank mates.

A sand substrate is best as coarser substrates like gravel often result in corydoras damaging their barbels. The long-finned bronze corydoras would look best against a lighter, more natural substrate to really highlight the greens and blacks on this fish. They will also love plants in the aquarium and places for cover through the addition of driftwood or caves.

Suitable Tank Buddies

Long-finned bronze corydoras are an incredibly peaceful fish which can be kept with an absolutely massive range of community aquariums. They do not display any aggression even when breeding and make for a perfect addition even with sensitive or shy fish. The main two factors which should be considered is that these corydoras are almost exclusively a bottom-dwelling species which means that any super active or large top-dwelling fish may outcompete the corydoras for food. They are also a species that may be easily picked on by fin-nipping fish.

Usually Compatible

community fish such as rams, tetras, angelfish, discus, rainbow fish and many more.

Sometimes Compatible

Larger peaceful South American cichlids such as Uaru, Severums and other fish which may outcompete them as they are a mostly bottom dwelling fish. Tiger barbs and other fin nippers should be avoided as they will absolutely make short work of the fins on these fish.

Rarely Compatible

Large and aggressive species such as oscars which may prey on the corydoras. This is especially important as corydoras have spines on their pectoral fins like many catfish, this can result in both the corydoras and the predator fish's death.

Feeding your Long-Finned Bronze Corydoras

Just like any other corydoras these fish are very easy to feed. They will take a wide range of pellets, flakes, and frozen foods. Just like any fish though they should be fed a varied diet with a mix of different foods. The ideal diet would be a good quality micro slow-sinking pellet or crushed flake, supplemented with frozen bloodworms or black worms or even live foods like baby brine shrimp or micro worms.
