Short Description

The Napo Corydoras (Corydoras napoensis) is a peaceful bottom-dwelling fish native to the Napo River, a tributary of the Amazon River in South America. Known for their active and social behavior, these Corydoras are excellent additions to community aquariums. They thrive in groups of five or more and are highly valued for their ability to sift through the substrate, keeping the tank clean while foraging for food. Their calm temperament makes them ideal tankmates for other peaceful species.

Origin

Native to South America, the Napo Corydoras is found in the Napo River, a tributary of the Amazon River. These waters are characterized by soft to moderately hard water, sandy substrates, and abundant vegetation, offering plenty of hiding spots and foraging opportunities.

Tank Requirements

A tank of at least 60 liters (15 gallons) is recommended for Napo Corydoras. Maintain water temperatures between 22-26°C (71.6-78.8°F), a pH range of 6-8, and water hardness of 4-20°N (71.43-357.14 ppm). Use a soft sandy substrate to protect their delicate barbels and add plenty of plants, driftwood, and rocks for shelter. Ensure good filtration with gentle water flow and regular water changes to replicate their natural environment and maintain optimal water quality.

Food and Feeding

Napo Corydoras are omnivorous and will readily accept a variety of foods. Provide high-quality flakes or sinking pellets as their staple diet, supplemented with occasional treats such as bloodworms, brine shrimp, or daphnia. Feeding them small portions twice daily will ensure they receive the nutrients they need while keeping the tank clean and free of uneaten food.

Compatibility

These peaceful fish are perfect for community tanks and can coexist with other non-aggressive species, such as tetras, rasboras, and small gouramis. Avoid housing them with overly active or aggressive fish that may outcompete them for food or cause stress. Keeping them in groups of five or more is essential for their well-being and encourages natural shoaling behavior.

Sexing

Males are generally smaller and slimmer than females, with more striking patterns. These differences become more pronounced as the fish mature, particularly during breeding periods.

Breeding

Breeding Napo Corydoras can be achieved by performing large, cooler water changes to simulate their natural spawning triggers. The female lays eggs on the tank glass or fine-leaved plants. The eggs hatch after 4-5 days, and the fry become free-swimming shortly afterward. Feed the fry newly hatched brine shrimp or rotifers to support their growth and development.

Lifespan

With proper care, Corydoras napoensis can live for over 5 years. Maintaining a stable environment, providing a varied diet, and reducing stress are key factors in ensuring their longevity.
