Corydoras Elegans breeding In Home Aquarium: method of reproduction.

Breeding Corydoras Elegans in the home aquarium is a relatively straightforward process. These fish are egg layers, and a separate breeding tank can be set up to encourage spawning.

To induce breeding, the water should be slightly cooler, and a partial water change can be performed, simulating the rainy season in their natural habitat. The aquarium should also be adorned with plenty of plants and caves for the breeding pair to lay their eggs.

The male will chase the female around, and when the eggs are laid, he will fertilize them. The eggs are adhesive and will stick to the plants and substrate. Once the eggs are laid, the parents should be removed from the tank to prevent them from eating the eggs.

The eggs will hatch in about 3 to 4 days, and after a few days, the fry will become free-swimming. At this stage, they can be fed infusoria or commercially available fry food, and with proper care, the fry will grow to maturity within a few months.
