1. Where will zebrafish lay their eggs Zebrafish lay their eggs in aquatic plants or crevices in Stone. If a large number of aquatic plants are planted in the fish tank where the breeder breeds zebrafish, they will hide in aquatic plants to produce. Although the production in water grass is hidden, it is inconvenient for male fish to fertilize, so the success rate of hatching is not very high. Zebrafish also like to lay eggs in crevices in Stone. When they give birth, breeders can lay a layer of pebbles on the bottom of the fish tank when they give birth. Fish eggs laid in crevices in Stone are easier to fertilize than in water and grass, and this can also prevent zebrafish from eating their eggs.
2. How do zebrafish eggs hatch1. Clean up unhatched eggs: Before hatching, breeders need to select unhatched eggs to avoid polluting water quality. Unfertilized fish eggs are generally white, while successful fertilization will become transparent.
2. Keep the water temperature constant: If breeders want to hatch zebrafish eggs, they must keep the temperature in the hatching tank constant. It is best to use a heating rod to keep the water temperature between 24-28 ℃. The higher the temperature, the faster the hatching speed of fish eggs, but the maximum temperature should not exceed 28 ℃, otherwise the fish eggs may be scalded to death.
3. Keep enough oxygen: The breeder should also install an oxygen pump in the fish tank, so as to ensure that the fish eggs can hatch better and faster, and avoid the lack of oxygen for small fish. In about 2-3 days, fish eggs can hatch into small fish.
