Spawning Process

Spawning happens in the morning after they're conditioned. Corydoras scatter their eggs among plants or spawning mops. It's important to keep the eggs away from the parents to prevent them from eating the eggs.

Egg Care

After spawning, the eggs need special care in a separate tank. Use gentle filtration to avoid fungal infections. Keep the water clean and at the right temperature for the eggs' health.

Raising Corydoras Fry

When the eggs hatch in 2-5 days, wait 1-2 days while fry absorb their yolk sac, then feed infusoria or commercial fry foods 2-4 times daily. Perform 10-50% water changes daily or every other day, matching water temperature carefully. Check water quality constantly for ammonia/nitrite. This frequent attention is key for fry survival and growth.

Breeding Corydoras catfish is both interesting and rewarding. It deepens your understanding of these fish. Plus, it helps the aquarium community by adding healthy fish.
