How to Diagnose
Follow these steps in order. Stop when you identify a likely cause and move to treatment.
- Inspect the eyes for signs of redness, swelling, or discharge.

How to Fix It
- Perform a partial water change to reduce ammonia and nitrite levels.
Change approximately 25-30% of the tank water weekly, ensuring a stable water chemistry.
- Increase the diet’s vitamin content with the addition of vitamin supplements or specialized food designed for eye health.
Ensure the supplements are appropriate for saltwater fish and not harmful to the other tank inhabitants.
- Administer antibiotic treatments if a bacterial infection is confirmed by a vet.
Follow the vet’s instructions for dosages and treatment duration.
- Remove any potential sources of stress, such as aggressive tankmates or inadequate tank size.
Ensure the fish is in a comfortable environment with appropriate water flow and temperature.
