  2. Create a breeding environment: Hognose cory require specific conditions to spawn successfully. You should provide a breeding box or a separate breeding tank with a substrate of fine sand or rounded pebbles. You can also add plant leaves or mops to stimulate breeding behavior.
  3. Introduce a breeding pair: Hognose cory breed in pairs, so you should introduce a male and female to the breeding environment. It’s important to ensure that they are healthy and sexually mature before attempting to breed them.
  4. Feed a nutritious diet: To encourage breeding, you should feed hognose cory a nutritious and varied diet. You can offer live or frozen foods, such as bloodworms, brine shrimp, or daphnia, as well as high-quality flake or pellet foods. Feeding small and frequent meals can also help stimulate breeding behavior.

They will then come together to release eggs and sperm. You should observe this behavior closely to ensure successful breeding.
  6. Remove the eggs: After spawning, the eggs will be scattered around the breeding box or tank. You should remove them carefully and place them in a separate tank or container with ideal water conditions. The eggs will hatch in 3-4 days, and the fry will become free-swimming in another 2-3 days.
  7. Provide proper care for the fry: Once the fry are free-swimming, you should feed them small amounts of freshly hatched brine shrimp or liquid fry food several times a day.
