zebrafish eggs Zebrafish eggs hatch by themselves. When hatching, the breeder can fish out the white eggs first, because these are unfertilized eggs or dead ones. Normal fish eggs are transparent, with a membrane outside and a small white spot in the middle. Only this kind of eggs can be hatched successfully. The breeder adjusts the water temperature to 24-28 C, and they can hatch in 2-3 days.
zebrafish after hatching 1. Feeding: Zebrafish do not need to be fed for the first three days after hatching, because they bring enough nutrients from their mothers to absorb. After three days, you can feed less egg yolk water, 5-7 times a day. Wrap the egg yolk in gauze and shake it gently in water. Just feed a little at a time and eat as little as possible, which can promote the development of the digestive system of zebrafish.
2. Water temperature: The newly hatched fry is still fragile at this time, and the water temperature should be controlled at 23 degrees. The water should be changed every day, and there should be no temperature difference when changing the water. The amount of water changed each time should not be too much, just a quarter.
3. Water quality: The small fry of zebrafish do not have too high requirements for water quality. They only need lower hardness and clear and clean water. It is best to change the water every day for a week after the fry hatches. It can not only maintain water quality, but also ensure sufficient dissolved oxygen in water.
