White spots on angelfish may be caused by ichthyophthiriasis, which is usually triggered by differences in water temperature. The following are the methods for treating ichthyophthiriasis:
Raising the water temperature: Increase the water temperature to between 28 and 32 degrees Celsius. This helps the white spot parasites fall off.
Changing the water: Change some of the water every 3 to 5 hours to gradually dilute the pathogens in the water.
Using medications: You can soak the angelfish in methylene blue solution for about 6 hours each day.
It's also very important to prevent the occurrence of ichthyophthiriasis. The following measures can be taken for prevention:
Keeping the water quality clean: Regularly change the water to ensure its cleanliness and avoid the growth of bacteria.
Controlling changes in water temperature: Avoid drastic changes in water temperature and keep it stable.
Using bactericidal salt: Add an appropriate amount of bactericidal salt to the water, which helps inhibit the growth of pathogens.
By taking the above measures, ichthyophthiriasis of angelfish can be effectively prevented and treated, ensuring the health of the angelfish.
