Can cloudy eye kill a fish? Find out if there is a reason to panic.
A cloudy eye can be very dangerous for your aquarium pets if it is not detected in time. It is a common condition among freshwater tropical aquarium fish such as Discus, Betta, and many more. In many scenarios, it is not actually a disease, but a symptom.
Beginners in this hobby are usually startled when they notice some characteristic symptoms in their pets, so is it any wonder that they often ask each other can cloudy eye kill a fish? Therefore, the following content will tell you everything you need to know about this condition, from the cause to the cure.
What Is Cloudy Eye In Fish?
Did you know that the structure of a fish’s eyeball is similar to that of humans? Namely, there is an outer layer, (cornea) that protects the inner structure of the eye from possible damage. Behind it is the iris responsible for adjusting the light, and then the lens, which bends the light coming into the eyes.
On the other hand, the lenses in a fish’s eyes are spherical. Simply put, their vision is incredibly clear in the middle, but gets pretty fuzzy toward the edges. Then it is very important to mention that behind the lens is the retina, the place where the light is processed. This is followed by the optic nerve, where the processed information is sent to the brain.
The cloudy eye is one of the most common diseases of marine and freshwater aquarium fish. The main causes are the accumulation of mucus and other secretions in the eyes of the fish, which ultimately results in impaired vision. In addition, the blurred eye is caused by gram-negative streptococcal bacteria or some other similar bacteria that most commonly attack injured or stressed fish.
When it develops, this disease causes the eyes of the fish to become cloudy, inflamed, or sunken.
