The head of the ponytail fighting fish turned white.

A friend of mine who raises fish told me that the color change of fighting fish is related to its movements. If the color is dim, it may be asleep. Of course, the possibility of getting sick is not ruled out. If the water is changed for observation, add salt. The amount of salt is about one sixth of that of an ordinary spoon. Take good care of them, I believe they will change back. Another possibility is that the weather is hot. When he suffers from heatstroke, he should remember to change the water the next day to keep the temperature in the water. In addition, if the temperature changes too much, he will be willing.
