Corydoras: Care & Breeding

Corydoras, affectionately known as “cories” by fishkeepers, are a species of freshwater catfish beloved for their peaceful nature and playful demeanor. They are native to South America and are a favorite among novice and experienced fish keepers due to their hardiness and sociability.

Care for Corydoras

Corydoras thrive in a well-maintained aquarium that mimics their natural habitat. A tank of at least 20 gallons is recommended, with a soft, sandy substrate to protect their delicate barbels (whiskers). They prefer slightly acidic to neutral water (pH 6.0-7.0) with a temperature range of 72-78°F (22-26°C).

These fish are bottom dwellers and enjoy a diet of sinking pellets, supplemented with live or frozen foods such as bloodworms or brine shrimp. Corydoras are also excellent scavengers, helping to keep the tank clean by consuming uneaten food.

Breeding Corydoras

Breeding Corydoras can be a rewarding experience. To encourage spawning, gradually lower the water temperature and increase the frequency of water changes. The female will lay her eggs on the glass or on broad-leaf plants, after which the male will fertilize them.

After spawning, it’s advisable to move the eggs to a separate tank to protect them from being eaten. The eggs usually hatch within 3-5 days, and the fry can be fed with infusoria or commercially available fry food.
