There are many reasons that can lead to long white hair on betta fish. It may be because the water quality is too poor, and the water mold viruses multiply in large numbers. When they multiply to a certain amount, they will cause betta fish to suffer from water mold, and at this time they will be covered with white hair. It may also be because there is too much water change, which leads to too much change in the water quality in the fish tank. At that time, they can't adapt, and at this time, they will see white hair on their bodies. It is also possible that when the seasons alternate, you don't pay attention to the heat preservation of the fish tank. As a result, the water quality in the fish tank changes too much, and their body resistance will decrease. At this time, they will also grow white hair.
2. Can the hair on the fighting fish be removed?The hair on the fighting fish can be removed. If you are suffering from water mold, you can soak the hairy betta fish in low concentration potassium permanganate for 20-30 minutes every day, and then smear their wounds with yellow powder after soaking. After about a week, they can recover, and then their white hair will disappear.
If it is caused by excessive changes in water quality, you can first check whether the pH value in the fish tank is in weakly alkaline water suitable for their life. If appropriate, don't worry about it, put them in a quiet place to rest, and they can disappear after a period of recovery. If it is caused by the change of water temperature, a heating rod can be used to adjust the temperature to about 28 ℃ and keep the temperature constant. After recovery, the white hair on the body can be removed.
