Corydoras kanei

This species is often confused with Corydoras atropersonatus and supplied under that name, as they bear a noticeable resemblance. Both catfishes share similar characteristics in coloration and body pattern. However, the true Corydoras kanei is usually slightly larger: adult specimens can reach 4 to 5 cm in length. Its distinctive feature is the predominant black speckles, which are located on a light background with pinkish hues and extend even to the caudal and other fins.

Corydoras kanei is endemic to Brazil, inhabiting the Rio Negro basin. In nature, these fish live in freshwater bodies, often preferring areas with soft water and shaded bottom sections, where they can hide among snags and fallen leaves.

This is a peaceful schooling species that feels most confident and active in groups of six or more individuals. The fish prefer to stay in the bottom layer, so free space on the substrate is important for them. They are compatible with most non-aggressive fish inhabiting the middle and upper water layers, such as characins, danios, or rasboras.

This catfish has been known to aquarists for many years, long before its scientific description was completed, when it was known under the identifiers C026 and C046. During this time, the species has successfully adapted to aquarium conditions, which sometimes differ significantly from its natural habitat. Keeping this species is quite simple, similar to other fish; the key is to maintain clean water within an acceptable range of temperature and pH/dGH values. This is achieved through regular aquarium maintenance. It is also important to provide a balanced diet, including a variety of foods; for example, dry and frozen sinking foods are well suited. Corydoras kanei should not be forced to search for food left by other aquarium inhabitants. Thanks to its calm and peaceful nature, this catfish coexists perfectly with most freshwater species.

In nature, they feed on small invertebrates and organic detritus. In the aquarium, they accept high-quality dry foods in the form of sinking tablets or granules, and also readily eat frozen foods such as bloodworms, brine shrimp, or tubifex. A varied diet promotes health and activity.

Breeding requires a separate spawning tank. Frequent water changes with cooler water and abundant feeding with live or frozen foods serve as a stimulus for spawning. The female lays about 60 eggs on the substrate. After spawning, the parents should be removed to prevent them from eating the eggs.

The species has robust health when water parameters are maintained and the substrate is kept clean. They are sensitive to high organic matter and nitrate content, which can lead to damage to their barbels and skin. Prevention includes regular water changes and the use of soft substrate without sharp edges.

When purchasing, choose active fish with clean skin and intact fins. It is important to check the condition of the barbels: they should be long and show no signs of erosion. Avoid individuals with sunken bellies or signs of apathy, as this may indicate emaciation or hidden diseases.
