the goldfish eggs? It is best to fish out the goldfish eggs gently by hand, which will not destroy the eggs and improve the hatching rate. Goldfish eggs have the phenomenon of sticking on the wall of the tank, it is best not to use the tank brush, scraper to scrape the eggs into the water, and then use a small fishing net to fish them out. This will destroy the eggs and reduce the hatching rate. When fishing for fish eggs, we should choose yellow eggs, which are fertilized eggs. The white eggs in the fish tank should be thrown away, which are not fertilized and will destroy the water body if they exist in the water for a long time. After the fertilized eggs are selected, they are placed in the tank to be hatched.
1. It is better to put aquatic plants into goldfish before spawning, so as to facilitate later egg retrieval. You can also put a leaky net in the fish tank, which can prevent the goldfish from eating the goldfish eggs themselves.
2. After spawning, the goldfish should be separated from the parent fish, and it is best to fish out the eggs by hand. The goldfish and its eggs are kept separately in order to prevent the goldfish from eating its eggs and protect the goldfish eggs. The parent fish can also be fished out separately and fed in a fish tank. After one day, the fertilized eggs should be screened out, and the fertilized eggs should be hatched in a special hatching tank.
3. Control the water temperature in the hatching tank, keep the water temperature at about 20 ℃, do not change the water during the hatching process, and ensure that there is sufficient oxygen. In about seven days, the little goldfish hatched out.
