10. Gill Flukes
Gill flukes are parasitic flatworms that attach themselves to the fish’s gills, causing respiratory distress.
Symptoms:
- Rapid or labored breathing

Freshwater Angelfish Diseases: Prevention and Care
Prevention is always better than cure when it comes to angelfish diseases. Here are some key preventive measures:
Maintaining Water Quality
Regular water changes, proper filtration, and monitoring of water parameters are crucial for preventing most angelfish diseases. Aim for weekly water changes of 20-30% and keep ammonia and nitrite levels at zero.
