1. How long does zebrafish lay eggs Zebrafish usually takes about 4-5 months from birth to adulthood. After they have grown up, they can lay eggs. Zebrafish grow and develop faster than other fish. If breeders can ensure that they live in a comfortable environment and have sufficient food and nutrition, they may mature in about 3 months. If they grow in an uncomfortable environment and have insufficient nutrition, their growth and development will slow down, and it will take about 5-6 months to mature.
Zebrafish reproduce in adulthood without seasonal restrictions, and can lay eggs as long as they live in a comfortable environment. Although they develop faster, it is best for breeders not to let them reproduce immediately. Because the organs of zebrafish that have just matured are unstable, immediate reproduction will affect the quality and quantity of offspring.
2. How to take care of zebrafish after laying eggs1. Fish eggs: If zebrafish eggs are not fertilized, the breeder can directly fish out the unfertilized fish eggs and throw them away. If zebrafish eggs have been fertilized, the breeder needs to control the water temperature between 24-28 ℃, keep the PH value between 6.5-7.5, and regularly apply oxygen to ensure sufficient oxygen, so that they can hatch faster.
2. Parent fish: Zebrafish females spend a lot of physical strength and energy when laying eggs, and breeders also need to prepare a separate fish tank for them. And feed them some nutritious and digestible food, so that they can recover their energy and physical strength more quickly.
