How does black appear to return a responsibility on parrot fish body? How to treat?

The water temperature fluctuates greatly: The black color on the parrot fish may be due to the great fluctuation of the water temperature, which stimulates the parrot fish. At this time, the temperature should be raised immediately, the water temperature should be raised to 25-28 C, and the water temperature should be stabilized, so that the black stripes will recede. | | The water quality is too poor: It may also be because the water quality is too poor and the water has not been changed for a long time. At this time, the new water should be replaced immediately. | | Illness: It may also be due to illness, such as black spot disease. At this time, methyl blue and other drugs can be used for its treatment.

One, water temperature fluctuation is big

1, reason: When changing water, do not care about the temperature of new water, pour cold water into fish tank directly. If the heating rod is not turned on in time during the seasonal alternation, the water temperature will fluctuate greatly, which will also stimulate the parrot fish, and black stripes will appear.

2. Treatment method: immediately use the heating rod to raise the water temperature to 25 ~ 28 ℃ and keep it.

2. The water quality is too poor

. 1. The reason is that the water is not changed for a long time, the water temperature of the parrot fish is high, the water body deteriorates quickly, and the growth of a large number of bacteria will threaten the parrot fish, resulting in black spots on the parrot fish.

2. Treatment method: immediately replace the new water, and confirm that the new water is non-toxic. Choose tap water, preferably in the sun for three days, exposure can remove chlorine in the water. In addition, we must remember to change water frequently, preferably once every three days.

3. Illness

1. Cause: Parrot fish suffer from black spot disease, which is mostly caused by bacteria in the water.

2. Treatment method: Insist on soaking in saline once a day, soaking in 2% -3% saline for 20 minutes to 30 minutes, which can play a role in sterilization. In addition, 0.3 grams of methyl blue and malachite green can also be put into 100 kilograms of water. After the mycelium falls off, the black color of the parrot fish will naturally recede.
