1. Reason: The parrot fish body contains the massive red pigment, therefore the fish body only then presents the bright red color. And these pigments are artificially provided. In the process of breeding, if the fish is not supplemented by pigments, the pigment content in the body will be reduced, resulting in whitening of the body.
2. The treatment method is that the feed with the reddening effect can be fed to supplement the pigment which is lacked in the fish body. Fish can be fed with feed containing carotene and other red pigments. When the pigment content in the fish body gradually increases, the white color of the fish body will disappear and slowly change back to bright red.
1. Cause: After the water quality worsens, the environment where the fish live breeds bacteria, which easily causes the gills of the fish to get sick. In addition, the water quality is poor, the dissolved oxygen in the water is very low, and the oxygen needed by fish to breathe is insufficient. Without sufficient oxygen for the fish to breathe, it will directly affect the health of the fish, make its body color temporarily fade, resulting in the phenomenon of white fish.
2. The treatment method is as follows: firstly, the living environment of the fish is improved. Put the fish in a clean water environment, and then add appropriate salt to the water to kill the bacteria infected in the gills. If the amount of oxygen in the water is still not enough for the fish to breathe, it is necessary to inject oxygen into the water. An oxygen pump can be instal to pump oxygen into that water for 1 to 2 hour every day to ensure the normal breathing of the fish. When the oxygen supply is stable, the fish's body will return to its original color.
