Bronze Corydoras (Corydoras Aeneus)

The Bronze Corydoras is a small, peaceful freshwater catfish that has become quite popular in the home aquarium. This species of fish is easy to care for and are incredibly hardy but can be somewhat shy. They are incredibly eye-catching because of the variety of body colours they possess, and they are fascinating.

They sport an elongated body, an arched back and have a short, rounded snout. This fish has two pairs of barbels present on their jaws which expand nearly up to the gill slits.

The Bronze Corydoras displays a yellow, crimson body with a whitish belly and a grey-blue back. The body flank is usually greenish, and the fins are pinky-red or yellow, and just before the dorsal fin, an orangy brown design is seen on the head.

Like all Corydoras, this species is protected with overlaying scales known as scutes or plates. Their dorsal fin has one spine with seven soft rays while the anal fin bears 1-2 spines with 5-6 soft rays. The caudal fin is forked, and an additionally pointed barb is present in the pectoral, dorsal, and adipose fins.

Natural Habitat

Rio de la Plata


In the home aquarium, the Bronze Corydoras will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is comparatively hard to distinguish between the male and female Bronze Corydoras. Generally, the female is larger has a slimmer body, and are far less colourful than the male also the females have a higher body frame than the males alongside their more significant abdominal region.
