1. How long does zebrafish conceive to give birth to small fish Zebrafish will not give birth to small fish after pregnancy because they are oviparous fish. When giving birth, the female fish first produces eggs, and then the male fish excretes sperm. Fish eggs need to become fertilized eggs before they can hatch small fish. Before laying eggs, the breeder needs to put the male and female fish together so that the eggs can become fertilized eggs. Generally speaking, female fish can lay eggs about 7 days after pregnancy. After laying eggs, it takes 2-3 days to hatch small fish.
2. How to raise small zebrafish1. Water temperature: Small zebrafish is just born and has poor adaptability to the environment. Breeders need to prepare a heating rod for them to keep the water temperature between 24-26 ℃.
2. Water quality: Zebrafish does not require high water quality, and breeders can keep the water quality neutral. If conditions permit, the PH value can be kept between 6.5 and 7.5. In the week before they are born, breeders should try not to change water, and try to change water in a small amount one week after they are born.
3. Feeding: Zebrafish are omnivorous fish, but there are not many kinds of food that newborn zebrafish can eat. Breeders can choose to feed some good-year shrimp eggs, cooked egg yolks, backwater, paramecium and other foods. These foods are rich in nutrition and easy to digest, which is of great help to the growth and development of small zebrafish.
