The eyes of fish are similar in structure to a human’s. The outer layer, also known as the cornea, protects the inner eye structure from becoming damaged. 

Just below this is the iris, which adjusts to allow more or less light into the eye. Behind this is the retina, where light is processed, then the optic nerve sends the processed information to the brain. One difference between the eye of a fish and a human, however, is that the lenses in a fish’s eye are spherical.



  • Protrusion of one or both eyeballs.

  • Stretching of the eye socket.

  • Discoloration or blood in the eyeball.

  • Rupture of the eyeball.

  • Cloudiness of the eyeball.



    Use anti Cloud Eye medicines according to the tank size (Dosage 10 ml per 100 liters)


The cloudy eye will usually go away of its own accord once its cause has been taken care of. For example, suppose it is determined that your fish’s infection caused the case of cloudy eyes. Once he has reacted to the medication and begun recovery, the symptom of cloudy eyes should diminish over time.
