Hello everyone, I am a professional aquarium fish ** science popularizer, and today I will bring you a topic about the white membrane of fish eyes. Many fish farmers may find that sometimes a white film will appear in the eyes of the fish, what is going on? What causes this white coat? Will it affect the eyesight and health of the fish? Can it disappear on its own? If not, what should we do? Let me answer them one by one.
The white membrane of the fish eye is actually the eyelid of the fish. The eyelids of a fish are a transparent film, and its role is to protect the fish's eyes from external irritation and damage. The eyelids of fish are usually clear and do not affect the vision of the fish and do not affect the aesthetics of the fish. However, sometimes, the eyelids of the fish will become opaque or even whitish for some reason, which is what we call the white membrane of the fish eye.
The main causes of the white membrane of fish eyes are as follows:
Poor water quality。Poor water quality is the most common cause of the white membrane of the fish eye. Poor water quality can cause irritation and infection of the fish's eyes, which can cause inflammation and edema of the eyelids, making the eyelids opaque and whitish. The manifestations of poor water quality are: unstable water temperature, excessive ammonia, nitrite, nitrate and other harmful substances in the water, lack of oxygen in the water, too many impurities and residues in the water, etc.
Injuries to fish。Injuries to fish can also lead to the appearance of the white membrane of the fish's eyes. Injuries to fish can be caused by fights between fish, collisions between fish and aquarium decorations or filters, or injuries sustained by fish during water changes or fishing. Injuries to fish can expose the fish's eyes to trauma and infection, which can lead to inflammation and edema of the eyelids, making the eyelids opaque and white.
Diseases of fish。Diseases in fish can also lead to the appearance of the white membrane of the fish's eyes. Fish diseases can be caused by weakened immunity in the fish, or by parasites or bacteria in the fish. Diseases in fish can cause infection and erosion of the fish's eyes, which can lead to inflammation and necrosis of the eyelids, making the eyelids opaque and whitish. The manifestations of fish diseases are: the body color of the fish becomes lighter, the body surface of the fish appears white spots, white spots, white hair, white membrane, etc., the respiration of the fish is accelerated, the appetite of the fish decreases, the activity of the fish decreases, and the body shape of the fish is deformed.
Whether the white membrane of the fish eye can heal itself depends on the cause and degree of the white membrane of the fish eye. If the alba is caused by poor water quality or injury to the fish, and the degree of the alba is not very severe, then it is possible for the alba to heal on its own. As long as we improve the water quality in time, avoid fish injuries, and provide a comfortable and safe environment for fish, the white membrane of the fish's eyes will slowly fade and the fish's eyes will return to normal. However, if the tunica of the fish eye is due to a disease of the fish, or if the degree of the tuna alba of the fish eye is severe, then it is impossible for the tunica of the fish eye to heal itself. At this time, we need to give the fish timely and correct **, otherwise the white membrane of the fish's eyes will become more and more serious, and even lead to blindness of the fish's eyes, or the death of the fish.
How to ** the white membrane of the fish eye, according to the cause and degree of the white membrane of the fish eye, different methods should be taken. Here are some common methods::
Improve water quality。Improving water quality is a basic and necessary measure for the white membrane of the fish eye. We should change the water regularly, keep the water clean and fresh, control the temperature and pH of the water, add the appropriate amount of salt and disinfectant, increase the oxygen content of the water, reduce the hardness of the water and harmful substances, and avoid excessive impurities and residues in the water. This relieves irritation and infection of the fish's eyes and promotes the rapid recovery of the fish.
Isolation**。Isolation is an effective and necessary measure for the tunica alba of the fish eye. We need to separate the fish with the alba membrane of the fish eye from the original aquarium and put it in a separate aquarium for isolation**. This can avoid the infection and spread of the white membrane of the fish's eyes, and can also avoid fights and injuries between fish, providing a quiet and comfortable environment for the fish, which is conducive to the recovery of the fish. The aquarium should keep the water quality clean and fresh, the water temperature should be appropriate, the amount of water should be sufficient, the appropriate amount of salt and disinfectant should be added to the water, the oxygen content of the water should be increased, the hardness and harmful substances of the water should be reduced, and too many impurities and residues in the water should be avoided.
Medications**。The drug is an important and necessary measure for the tuna alba of the fish eye. We need to choose the appropriate drug according to the cause and degree of the white membrane of the fish's eyes, and give the fish a drug**. The purpose of the drug** is to eliminate inflammation and infection of the fish's eyes and promote the healing and recovery of the fish's eyes. There are several ways to use drugs:
Topical medications。Topical medications are medicines that are applied directly to the eyes of the fish, such as eye drops, eye ointments, eye creams, etc. The advantage of topical drugs is that they can act directly on the eyes of fish, and the effect is fast and small. The disadvantage of topical drugs is that they need to be used frequently by fish, which is inconvenient to operate, and is easy to be shaken off or washed away by fish. The method of using topical drugs is: first wipe the fish's eyes with a cotton swab or a clean cloth to remove the white film and secretions on the eyelids, then apply the medicine to the fish's eyes, gently massage to allow the drug to be fully absorbed, use 2-3 times a day for 7-10 days, or until the fish's eyes return to normal.
Medications taken internally。Oral drugs refer to drugs that enter the body of fish through oral administration or injection, such as antibiotics, anti-inflammatory drugs, antiparasitic drugs, etc. The advantage of taking the drug internally is that it can be used to treat fish diseases systemically, and the effect is long-lasting and small. The disadvantage of oral medication is that it needs to be taken orally or injected into fish, which is inconvenient to operate and easy to cause discomfort and resistance in fish. The method of using the drug for internal administration is to calculate the amount of drug that the fish needs to take each time according to the weight of the fish and the dose of the drug, and then dissolve the drug with food or water, and give it to the fish orally or injected, using it 1-2 times a day for 7-10 days, or until the fish's eyes return to normal.
Bath medicine**。Bath medicine** refers to the method of dissolving the medicine in water and allowing the fish to soak in the medicine, such as salt bath, iodine bath, ofloxacin bath, etc. The advantage of bath medicine is that it can be used at the same time for diseases on the eyes and body surface of the fish, and the effect is good and small. The disadvantage of bath medicine** is that it is necessary to prepare a separate aquarium for the fish, which is inconvenient to operate and easy to affect the water quality. The method of using bath medicine** is: first calculate the amount and concentration of the potion that the fish needs to soak each time according to the weight of the fish and the dose of the drug, then dissolve the medicine in the water, put the fish in the potion, let the fish soak in the potion, use it 1-2 times a day, soak for 15-30 minutes each time, continue to use it for 7-10 days, or until the fish's eyes return to normal.
The above is the topic I introduced to you about the white membrane of fish eyes, I hope it will be helpful to you.
