There are many reasons for the fading of ornamental fish. Experts point out that there are roughly the following: unstable water quality - each freshwater fish has a water pH suitable for growth. If too many different types of fish are kept in a fish tank, in addition to the possibility of fighting, the difference in pH between cold and tropical fish and water can also cause poor growth and development of ornamental fish.
Nutritional deficiency - If the general ornamental fish is only fed with ordinary feed, it is inevitable that they will be malnourished over time. Lack of sunlight - Although ornamental fish grow in water, if they lack sunlight, the color of the fish body will gradually fade. The color will fade - In addition to the problem of breeding skills, another important factor for the fading of ornamental fish is the dyeing and brightening treatment.
There are many ornamental fish in Taipei that have been dyed. The most common one is the transparent glass fish. The ornamental fish exported from Thailand are injected with various pigments into the fish body. Other methods such as using brightening feed and injecting hormones can change the color of the fish body. As the fish are not fed with feed containing brightening agents, the color will naturally become lighter over time.
