Many people have experienced the death of a goldfish at some point in their lives. The idea of bringing a goldfish home from the fair in a goldfish bowl, feeding it, and expecting it to live only a short period before having to flush the poor goldfish down the toilet is outdated.
Most people now know, or should know, goldfish that are properly cared for can live for many years. A child may not ever have to experience the heartbreak of a dying goldfish.
To start with, a goldfish bowl is not a proper home for a goldfish. It is recommended that one goldfish be housed in a 10-gallon fish tank. A small goldfish bowl is not even close to this size. The goldfish simply do not have enough room to swim and grow. They cannot thrive in such a small environment.
Goldfish bowls are inexpensive and some people still purchase them for their goldfish. If a bowl must be used, it should only be used for a short period. The bowl should not be the long-term home for the goldfish. If the goldfish is not moved to a larger tank, the owner will more than likely see signs of a dying goldfish in less than a year.
Even when a goldfish is placed in a large enough tank, the tank will still need to be maintained to ensure the goldfish remain healthy. It is necessary to clean the tank on a regular basis. Installing a filter will help with some of the cleaning issues.
It is also important to change a portion of the water on a weekly basis. This is done by taking a small amount of the water out of the tank and replacing it with fresh bottled or conditioned water. Keeping the tank clean will help rid toxins that cause disease and minimize the chances of finding a dying goldfish.
If all preparations have been taken to ensure the goldfish are safe and healthy, and a goldfish appears to be sick, there are some signs that could tell if it is a dying goldfish or just a sick fish. Very ill fish tend to gravitate to the bottom of the fish tank. If the fish is not eating and seems lethargic, it might be best to isolate and medicate the goldfish. It may even be possible to save the goldfish if the illness was caught quickly enough.
