after artificially squeezing the eggs? The goldfish will change the water after half an hour after artificially squeezing the eggs. Because of the hatching of fish eggs. At the same time, it will also reduce the over-fertilized fish eggs in the water, and there will be residual semen in the water. They stick to the walls of the tank, which may breed bacteria in the water, which is not conducive to oxygen levels. Once the dissolved oxygen is reduced, the eggs can not be hatched smoothly. Therefore, in order to make the eggs hatch normally and ensure the cleanliness of the water, the water should be changed after half an hour of fertilization.
after artificial squeezing of goldfish eggs? In order to ensure the smooth hatching of fish eggs, it is necessary to change water in time and clean up the semen attached to the water. However, it should be noted that the new water should be used in advance, and the fresh tap water should be dried for several days to remove chlorine and reduce the content of chlorine in the water. Because chlorine is harmful to fish, especially to gills and lungs.
When changing water, it is necessary to change a small amount of water to avoid sudden changes in the water quality environment. One third of the water can be changed each time. In addition, the parent fish needs to be fished out of the old fish tank in time and put into the new fish tank. However, use the water from the original fish tank. Because the body of the female fish is very weak after spawning, it can not adapt to the sudden change of water environment. At the same time, when changing water for the original fish tank, water should be extracted from the bottom.
