to hatch? Generally, goldfish eggs do not need oxygen to hatch, but it also depends on the number of hatched eggs and the water quality. When the water quality in the tank is relatively stable and the number of hatched fish eggs is not too large, the breeder does not need to oxygenate them separately. Because the oxygen content in the water itself is enough for their hatching, too high oxygen concentration is also harmful to their hatching.
If the number of hatched fish eggs in the tank is relatively large and the water quality is unstable, the breeder had better give them oxygen to prevent the lack of oxygen from affecting the success rate of their hatching. But even if the oxygen, the daily oxygen time can not be too much, to maintain about four hours.
should we pay attention to when goldfish eggs hatch? 1. Clean up the unfertilized white eggs from the fish tank as much as possible, because the white eggs have become dead eggs. If the breeder does not clean them up in time, they will rot and mildew in the water, thus polluting the water quality, which is not conducive to the hatching of the rest of the eggs.
2. Try to let the eggs hatch in the vat, because the water temperature in the vat is relatively stable, which can prevent the temperature difference between day and night from being too large, and also avoid their hypoxia.
