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.
Goldfish breed in the Spring, so you want to replicate the heating up of the water. To do this, first drop the temperature to between 10Â°C (50Â°F) and 12Â°C (54Â°F). Then, when you're ready to breed, raise the temperature by 2Â°C (3Â°F) per day, until the temperature is between 20Â°C (68Â°F) and 23Â°C (74Â°F). partial water change is important to the general wellbeing of your fish and in stimulating breeding conditions specifically. Remove as much as 20% of the water in your tank daily, being sure not to exceed this amount. 1  Remember to add water conditioner to the water that you cycle into the tank.
