Pigeonfish Eye White Membrane: What's the Reason?
The Causes and Symptoms of Blindness in Parrotfish
Causes: Parrotfish can suffer from a condition known as "blindness," which is often due to poor water quality in the aquarium or injuries to their eyes from fighting or collisions. These injuries can then lead to infections by tuberculosis or Vibrio bacteria, resulting in the clouding of their eyes. Additionally, an excess of nitrogen in the aquarium water can enter the parrotfish's body, causing the blindness symptom. Moreover, if the parrotfish has white spot disease, it can also lead to the formation of a white film over their eyes.
Symptoms: In the early stages of the blindness, the parrotfish's eyes will appear to have a white mist, with a visible white film inside and the eyes becoming cloudy. As the condition progresses, the eyes may swell and be accompanied by the appearance of white fluffy material.
How to Treat Parrotfish Blindness?
If the white mist is only on the surface of the eye, it is likely due to poor water quality. The keeper should immediately replace a third of the aquarium water and use a heater to raise the water temperature to 30°C, maintaining this for three to four days. If the parrotfish's condition improves, continue to change a quarter of the water every three days until the fish's eyes are fully recovered. Note: When changing water, be careful to control the water temperature difference (within 2°C) to avoid causing other abnormal symptoms in the parrotfish.
If there is white mist on both the surface and center of the eye, along with white fluffy material inside, it is likely due to an infection after an eye injury. In addition to changing the water, raising the water temperature, and using salt for medication, the keeper should also treat the fish with antibiotics, yellow powder, penicillin, and gentamicin. During this time, the keeper should monitor the parrotfish's improvement and decide whether to continue medication. If the symptoms improve, gradually reduce the dosage.
If the white film on the eyes is due to white spot disease, the keeper should first change the water, use salt medication, raise the water temperature to 30°C, and stop feeding the parrotfish for 1 to 2 days. At the same time, cover the dragon fish with the medication used to treat white spot disease. Once the white spot disease in the parrotfish improves, the white film in the eyes will also disappear.
