1. Reason: just for the new water will make the fish can not adapt to the new environment, which appears to turn white. In addition, not changing water for too long will lead to deterioration of water quality. Fish live in poor quality water for a long time, and the toxins accumulated in the water will also cause it to turn white.
2. Treatment: water caused by the new white can not be too concerned about, and so on after a period of time to get used to the fish, white will slowly disappear, to restore their own color. When the water quality is too poor, the water needs to be replaced, but not all the water should be replaced, and two-thirds or three-quarters of the old water should be retained.
