Goldfish is one of the most popular freshwater aquarium fish species kept in home aquariums all over the world. They come is variety of shapes, colors and currently there are more than hundreds of goldfish varieties crossbred and produced as ornamental fish. Their graceful movements coupled with their bright coloration and fancy features, often makes them the first choice of fish among hobbyist.
Goldfish are not the type of fish suitable for beginners due to their nature of heavy waste generation that requires a lot of care and maintenance. If one is unable to commit their time and effort to look after this delicate aquarium fish, it will usually result in poor water quality that often leads to introduction of fish disease.
Most people always have the misconception that keeping goldfish is somehow relatively easy without needing much attention. Goldfish are often stuffed in bowls with poor water quality and most of the times, are often fed non-stop until they become bloated. This often led to introduction of disease, while others become stunted due to limited space and lack of proper nutrition and in worst case, death.
Goldfish generally thrive in water temperature ranging from 20 to 22degC with pH around 7.5. Some are slow swimmers while others are more agile. They are not aggressive and would not harm other fish that housed together with them in the same aquarium. However, due to their heavy waste generation and feeding frenzy, most people regard them as unsuitable for community aquarium. Goldfish are not fussy when it comes to diet and if well cared for, they can survive for long period of time up to 20 years.
