1. Reason: The discoloration of betta may be caused by species. A marble-colored betta, for example, constantly changes its color. Its color may become lighter with age, and it looks like it has faded.
2. Treatment method: This is due to the variety and cannot be changed. If you don't want this problem, you should choose a good variety when you buy betta fish, and don't choose a variety that changes color frequently.
1. Reason: If the breeding betta is too old, then the color of its body will gradually fade. This is because with the increase of age, the metabolic rate of the body slows down, and the ability to produce pigment decreases.
2. Treatment: There is no way to deal with this situation, because it is natural aging. It can only properly improve the breeding environment and slow down its discoloration.
1. Reason: If the environment in which the betta is cultured suddenly changes, for example, if it is put into cold water from warm water, then it may have the problem of fading because it cannot adapt to the new growing environment.
2. Treatment method: In this case, put the betta in an environment with water temperature of 25-28 ℃ in time for maintenance, and change the water every 2-3 days. During this period, we should pay attention to disturbing it less and let it adapt to the new environment slowly. When it adapts to the new environment, the color may be restored.
