koi carp after throwing seeds 1. Prepare the container: fish out the fertilized eggs from the fish tank and put them into the prepared container. Ordinary families can use wooden or dark plastic basins, and conditional isolation nets can be used. Some aquatic plants can be put in the basin to facilitate the attachment of fish eggs.
2. Keep the temperature: The hatching speed is closely related to the water temperature. If the water temperature is 18 degrees, it usually takes 5 days to hatch. If the water temperature is 20 degrees, it takes 4 days to hatch. If the water temperature is 25 degrees, it only takes three days to hatch. So it is better for the breeder to keep the water temperature between 23-25 degrees.
3. Maintain water quality: The best water quality for hatching koi is tender green water, because this water quality can effectively inhibit the growth of bacteria and speed up the hatching of koi.
4. Timely treatment of moldy fish eggs: Unfertilized fish eggs are prone to Saprolegnia. If unfertilized fish eggs are found, they need to be fished out as soon as possible to avoid polluting the water quality.
the hatched koi? The newly hatched koi do not need to be fed for the first three days. They can absorb enough lecithin from their mother's body. After three days, you can feed less egg yolk water or shrimp eggs. Egg yolk water is more likely to pollute the water quality, so you can give priority to shrimp eggs. When they can find their own food, they can feed some feed or mealworms.
