for goldfish to spawn. Goldfish spawning can not be completed at one time, but intermittent spawning, it takes many times to finish spawning. If the goldfish has laid eggs several times and its belly is still bulging, it means that there are eggs in the goldfish's belly and it is necessary to wait patiently. When all the eggs are discharged, the belly will naturally stop bulging. In order to prevent goldfish from eating their eggs, fish and eggs need to be raised in separate tanks. You can also put a filter screen in the fish tank, so that the eggs laid will leak into the filter screen, which can effectively protect the fish eggs.
1. The water temperature should be a little higher than usual, preferably around 23 degrees Celsius, so as to speed up the hatching of fish eggs and improve the hatching quality of young fish. The water temperature should not be lower than 20 C, otherwise the hatching speed is very slow. It should not be higher than 25 C, otherwise the eggs may die because they are not resistant to high temperatures.
2. Unfertilized fish eggs should be fished out to avoid damaging the water body. Fertilized fish eggs are transparent and have black spots, while unfertilized fish eggs have no black spots and will grow hair.
3. Goldfish eggs should be taken out manually. It is best to gently take out the fertilized eggs by hand and put them into a fish tank with changed water to hatch slowly. Because there are semen and other impurities in the water after the goldfish lays eggs, it is easy to deteriorate and breed bacteria. If the environment is not changed, the fertilized eggs are likely to die.
