Skunk cory

Geographic Origin and Biotope: Upper Amazon River basin in Peru and Ecuador. Found mainly in small tributaries, oxbow lakes and slow streams with sandy bottoms rich in vegetation and dry leaves.

Taxonomy and Morphology: Skunk Corydoras (Corydoras arcuatus). Characterized by the distinctive uninterrupted black band running along the entire back. Rounded snout and compact armored body.

Social Behavior: Schooling species, peaceful and quiet. Essential to keep them in groups of at least 6 specimens to replicate natural dynamics and prevent stress and shyness.

Coloration and Sexual Dimorphism: Whitish-gray body crossed by a thick and clear arched black stripe (hence "arcuatus") that goes from the mouth, passes over the eye and runs along the back to the base of the tail. Females are rounder.

Aquarium Setup: Tank of 60-80 cm (24-32 inches). Mandatory use of non-sharp fine sand for the well-being of the barbels. Roots, floating plants to shield the light and ceramic hiding places complete the layout.

Diet and Feeding: Bottom omnivore. Feeds by rummaging the sand. Administer specific feeds for bottom fish, bloodworms, daphnia and tubifex. Do not rely solely on the leftovers of other fish.

Water Quality: Prefers soft and slightly acidic waters, but is very adaptable if the water is well oxygenated and nitrate-free. Requires regular siphoning of the sand to avoid bacterial infections.

Compatibility and Tankmates: Ideal companion for small Tetras, Rasboras, Otocinclus and peaceful dwarf Cichlids. Given its small size, it should not be paired with large predators that could swallow it whole (choking on the spines).

Aquarium Reproduction: Similar to other Corydoras: stimulated by cold water changes. The eggs (very small) are laid on leaves or glass in areas of strong current. Parents may prey on their own eggs.

Risks and Diseases: Barbel infections caused by unsuitable gravel are the main cause of death in the aquarium. Avoid sudden osmotic changes during water changes.
