Any fish into the tank when there will be no adaptation to the situation, parrot fish is the same. Because of the change of living environment, it needs a period of time to re-adapt to the surrounding environment, at this time will inevitably be frightened, resulting in stress response, leading to black spots. This situation does not need to do anything, until it adapts to it, during which do not feed, because feeding does not eat, but also may affect the water quality.
Changing too much water is actually similar to the situation of entering the tank. Once the amount of water is changed by more than half, the water condition will be changed after the new water is injected. The parrot fish needs to re-adapt, so black spots will appear. Usually, the amount of water should be changed about a quarter, if there are impurities in the water body, it can be changed more appropriately, but the amount of water should be between one third and one half.
If the water quality is polluted, the parrot fish will also appear black spots, especially when the breeding density is very high and the water is not changed frequently, this situation is very easy to occur. Therefore, water should be changed regularly to reduce the feeding density. In addition, the acidity and alkalinity of water should also be controlled, it likes weak acidic soft water, the water quality in the north is hard, it needs to be adjusted with soft water resin.
Parrot fish is a tropical fish. Although it has a strong ability to adapt to water temperature, long-term low water temperature will also affect its development, resulting in black spots on the body surface. Usually, the temperature should be controlled at about 28 C. In winter, heating rods are needed to heat up the water in the fish tank.
