for goldfish eggs to hatch. When the water temperature in the tank is between 15 and 20 degrees Celsius, the hatching speed of goldfish eggs is relatively slow. It takes about seven days to hatch. The hatching rate at this temperature is also relatively low. If the water temperature in the tank rises to about 20 degrees Celsius, the eggs can hatch into small fish in about four days at the fastest. If the water temperature can reach 20-25 C, then they will hatch faster, only about 2-3 days, can be hatched smoothly.
goldfish eggs after hatching 1. Feeding: Newly hatched fish do not need to be fed for the first three days, because they have their own yolk sac, which contains rich nutrients for young fish to absorb, which is also conducive to their better and faster adaptation to the external environment. After three days, small fish can be fed some crushed egg yolk or water, which can promote their growth. But be careful not to overfeed, and remember that too much is too little.
2. Water quality: The newly hatched fish have strict requirements for water quality, and the breeder should keep the water temperature constant. Be careful not to let the water temperature fluctuate violently, so as not to cause damage to them.
