Parrot fish is suitable for living in waters with water temperature of 25-30 ℃. If the temperature changes, it is easy for the fish to have a stress reaction, so that the color will be dim, lose luster, and even black stripes may appear. Therefore, we must pay attention to the control of water temperature, and the temperature difference before and after water exchange should not exceed 0.5 C. In addition, when the season changes, we should also prevent temperature changes, so as not to affect the fish.
If the parrot fish is relatively healthy, it is usually not necessary to add salt to the water. Adding salt will change osmotic pressure, affect the metabolism of fish, and then increase a certain load, resulting in it does not like to swim. Usually, the salt content in water is between 0.1 and 0.3%, which can reach a balance, and once it exceeds, it will not be good. Moreover, it is not easy to grasp the concentration of salt, which can easily cause physical discomfort.
Parrot fish like weak acid soft water, because some species can not close their mouths, the control ability of swallowing and spitting water flow is relatively weak, so we should pay attention to controlling the dissolved oxygen in the water, otherwise it will affect its breathing. In addition, this kind of fish has a mixed diet, regularly feeding fresh small fish and shrimp, you can also prepare some artificial bait, bait is best rich in astaxanthin and carotene, so that its body color can be more bright.
