What is the white coating over eyes of a fish?

Here's why:

* Fungal Infections: Fish are susceptible to fungal infections, particularly if they are stressed or have a weakened immune system. These infections can manifest as a white, fuzzy coating on the eyes, fins, or body.

* Other Possibilities: While fungal infections are the most common cause, other possibilities include:

* Bacterial Infections: Some bacterial infections can also cause a white coating, but this is less common than fungal infections.

* Parasites: Certain parasites, such as protozoans or flukes, can also cause a white coating over the eyes.

* Mechanical Injury: A scratch or injury to the eye can lead to inflammation and a white appearance.

Important Note: If you notice a white coating on a fish's eyes, it's crucial to seek veterinary care as soon as possible. A qualified fish veterinarian can properly diagnose the cause and recommend appropriate treatment.
