How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Inspect the fish's eyes for any signs of injury or discharge.
Look for any physical damage or a white, cloudy film.
- Check the water parameters for ammonia, nitrite, and nitrate levels.
Use a water test kit to measure these parameters.
Recommended: Water test kit - Observe the fish's overall health and behavior.
Look for signs of stress or other symptoms of disease.
- Perform a physical examination of the fish for other signs of infection or disease.
Use a magnifying glass to inspect the fish's body for lesions or spots.
Recommended: Magnifying glass - Consider the fish's age and history to assess the likelihood of genetic factors.
Older fish may be more prone to genetic issues.
How to Fix It
- Improve water quality by performing regular water changes and treating for ammonia, nitrite, and nitrate.
Change 20-30% of the water weekly and use water conditioners to neutralize harmful chemicals.
- Administer appropriate antibiotics or antiparasitic treatments as prescribed by a veterinarian.
Follow the vet's instructions carefully to avoid resistance and side effects.
- Ensure the fish is receiving a balanced diet with essential nutrients.
Provide a varied diet that includes high-quality fish food and occasional treats like vegetables or fruits.
- Isolate the affected fish to prevent the spread of infection to other tank mates.
