The seven-color angelfish is a kind of fish that is more suitable for viewing. When breeding it, water quality is a problem that needs special attention. The discolored angelfish is a tropical fish originally found in the Amazon River basin. The water there is slightly acidic because there are so many fallen leaves rotting. Therefore, when we breed colorful angelfish, it is better to provide them with weak acidic water.
The most commonly used water is tap water. However, tap water in the home is generally alkaline. At this point, you can first use PH test paper to detect the PH value, if it is not appropriate, you can use potassium dihydrogen phosphate or oxalic acid to adjust, and then use. In addition, tap water also contains more chlorine, which is harmful to colorful angelfish, so we need to do a good job in removing chlorine. The simplest way is to put water in the sun for a period of time. In addition, there are also special chlorine removal agents, which can be considered for use.
To breed the seven-color angelfish, you need to pay attention not only to the type of water, but also to ensure that the water quality is clean, so you need to change the water in time. If you have time, you can change the water every day, one fifth of each time. If there is no time, you can change water about twice a week, but the amount of water change each time needs to be more, about one third of the whole is more appropriate. It is better to change water regularly, so as to ensure the stability of water quality and not to change the water environment too much. When changing the water, pay attention to the slow injection.
