The white patches on betta fish may be caused by various reasons, mainly including parasitic infections, water quality problems, and temperature changes.
Parasitic Infections
The white patches on betta fish may be due to white spot disease caused by parasitic infections. This parasite is called Ichthyophthirius multifiliis. It will lay eggs on the fish's skin, forming small white dots, which will lead to the fish being in a poor condition and even affect its mobility and immune system.
Water Quality Problems
Not changing the water in the fish tank for a long time will cause an increase in impurities in the water and the reproduction of germs, which in turn will trigger the appearance of white patches on betta fish. To solve this problem, the following measures can be taken:
Isolate the sick fish to prevent the spread of germs to healthy fish.
Clean the fish tank and soak the fish tank with coarse salt for sterilization.
Regularly change the water in the fish tank to keep the water quality clean.
Temperature Changes
In autumn and winter, rapid temperature changes in the fish tank can cause harm to betta fish, resulting in the appearance of white patches on them. To solve this problem, a heating rod can be placed in the fish tank to keep the water temperature stable.
Treatment Methods
Isolate the Sick Fish: Place the fish with white spot disease alone in an isolation tank to prevent the spread of germs.
Improve Water Quality: Maintaining good water quality is the key to preventing and treating white spot disease. Regularly change a part of the water and clean the bottom residues in the fish tank.
Use Medication: You can use powerful antibacterial drugs such as yellow powder + oxytetracycline or special sterilizing agents for treatment.
Provide a Good Diet: Provide the fish with a balanced diet, including nutrients and vitamins that are beneficial to the health of the immune system.
By using the above methods, the problem of white patches on betta fish can be effectively prevented and treated, and the health of betta fish can be maintained.
