Axelrod's Corydoras

Adults of this species grow up to 4–5 cm in length. Their coloration is predominantly pink, which is the basis for their common name. The body pattern includes a diagonal stripe on the head and black stripes that run along the back and sides. A small number of dark speckles can be seen between these stripes.

The species inhabits South America, primarily the Meta River basin, a tributary of the Orinoco in Colombia. In nature, it prefers calm sections of rivers and soft-water bodies, where it stays in the bottom layers among vegetation and snags.

A peaceful and social schooling fish, most active at dusk and night. It is recommended to keep them in groups of 4–6 individuals. Compatible with most non-aggressive freshwater fish of comparable size, but not recommended for cohabitation with small shrimp species, which may be perceived as prey.

Axelrod's Corydoras does not have special requirements for keeping and will not cause significant trouble if suitable conditions are provided: balanced nutrition and peaceful cohabitation. For a group of 4–6 individuals, an aquarium of at least 40 liters is recommended. The setup is simple, with primary attention paid to the bottom layer. It is desirable to use soft substrates, such as large sand or fine rounded gravel, and to provide hiding places. It is crucial to maintain high water quality within acceptable temperature and hydrochemical parameters. For this, the aquarium must be equipped with the necessary equipment, particularly a filtration system, and require regular maintenance: weekly partial water changes and removal of accumulated organic waste, such as food remnants and excrement. Regarding feeding, the fish readily accept most common aquarium foods—dry, frozen, and live. Given the bottom-dwelling nature of the Pink Corydoras, preference should be given to sinking foods, as they will find it difficult to feed from the surface. In terms of behavior and compatibility, it is a peaceful and social fish that prefers to stay in groups of 4–6 conspecifics. They are compatible with other Corydoras species, but it should be noted that different groups do not mix and each species tends to keep to itself. Axelrod's Corydoras coexist well with most non-aggressive freshwater fish of comparable size.

An omnivorous species, in nature, it feeds on benthic crustaceans, insects, and organic detritus. In the aquarium, specialized sinking foods—tablets or granules—should be used, as the fish feed exclusively at the bottom. The diet can be supplemented with frozen or live foods.

Spawning is paired or communal, stimulated by water changes and temperature reduction. The female lays fertilized eggs on plant leaves or smooth surfaces. Parents do not care for their offspring and may eat the eggs, so it is recommended to remove the breeders after spawning. Incubation lasts 3–4 days.

The species has a strong immune system when kept under proper conditions. They are most sensitive to water quality and substrate cleanliness. Accumulation of organic waste can lead to bacterial infections of the fins and skin. It is important to avoid injuring the barbels with sharp substrate, which can lead to infections.

When purchasing, choose active individuals with clean skin without spots, ulcers, or fin damage. It is important to check the integrity of the barbels, as their absence is a sign of poor keeping conditions. The fish should show interest in foraging for food at the bottom, rather than appearing emaciated or apathetic.
