by itself. 1. Reason: Parrot fish are timid. When they suddenly turn on the light or feed, they will be frightened by knocking on the fish tank. If they are frightened, they will easily fade or turn black.
2. Treatment: If the fish is frightened, the breeder can move the tank to a quiet and dark environment and wait for the parrot fish to recover by itself. If the tank cannot be transferred, a black cloth can be placed around the tank to give the parrot fish a sense of security.
explosion 1. Reason: Parrot fish do not require high water temperature, but they are more sensitive to temperature difference. If the temperature difference exceeds 2 degrees when changing water, it is easy for them to produce stress reaction, resulting in tail blackening. Poor water quality can also cause them to become lighter in color or black in tail.
2. Treatment: In this case, there is no need for medication. You only need to raise the water temperature to 28 degrees and keep the PH value in the water between 6.5 and 7.0. The parrot fish can recover by itself in about 3-5 days. If you are worried, you can add some coarse salt to the fish tank.
1, reason: parrot fish tail injury or black spot disease can also lead to tail blackening, this situation is mainly due to bacterial infection, breeders can first observe whether there is a wound on the tail.
2. Treatment: If there is a wound, it can be washed with potassium permanganate solution first, and then bathed with furacilin powder mixed with water. If there is no wound on the tail, it can be bathed directly with furacilin.
