is the spawning of a small goldfish? When a small goldfish spawns, the abdomen of the female fish will become enlarged and look soft and full. When the goldfish is spawning, the male will keep chasing the female, and sometimes the female and the male will chase each other. When the male fish starts to put his head on the belly of the female fish, the female fish will lay eggs, and the breeder needs to prepare a nest for them in advance and put it into the fish tank. After the female fish lays eggs, the male fish will come forward to discharge sperm, and the combination of the two will become fertilized eggs. The newborn eggs of small goldfish are light yellow, and the diameter of the eggs is 1-1.2mm. When they become fertilized eggs, the color will become gray-white, and there will be a small black spot in the middle of the fertilized eggs.
the eggs of small goldfish After fertilization, the breeder can keep the water temperature at 30 C and turn on the oxygen pump to ensure sufficient oxygen in the hatching tank. Do not change water during this period to avoid environmental changes affecting the hatching rate of fish eggs. Also do not open the filter to avoid too much suction in the filter to suck the fish eggs in. During the incubation period, the breeder should control the temperature difference between 0.5 ℃. As long as the environment is suitable, goldfish can hatch in about 2 days. The newly hatched young fish will not swim, but they will carry their own lecithin, enough time for them to absorb 2-3 days. The breeder can feed the young fish 3 days after birth.
