According to data put together by Harvard's Amitabh Chandra, which the New York Times published in raw form in 2006, it was the least common birth date for more than two decades in the late 20th century; September 16 comes in at the other end of the spectrum, as the most common date for babies to be born.
A Goldfish will grow quicker if you increase its metabolism slightly. This can be done by keeping the water at summer temperatures of around 65F to 70F. Goldfish kept at this higher temp will also need added space (2 gals per inch of fish), air bubbles and a really good filtration system.
Therefore, to encourage your goldfish to lay eggs, you should lower the temperature of your tank in the winter months to between 10Â°C/50Â°F and 12Â°C/54Â°F. Then, when you want to induce breeding, gradually raise the temperature of the water to between 20Â°C/68Â°F and 23Â°C/74Â°F.ir supply. Itâs important to realize that the hotter your goldfishâs water gets, the less oxygen there is in the water. Of course, goldfish need oxygen to live, so you must ensure that your tank has an adequate âaeration systemâ (a system of adding air into the water).
