Betta Fish Cloudy Eye Conditions and TreatmentBetta fish cloudy eye is a serious disease that can worsen if proper care is not taken as soon as possible. This condition can turn from a simple white spot on betta eye to a whole eye getting infected.

It is important to find the reason behind this condition to successfully control it and prevent other betta’s (if any) from contracting the disease.

To find out more about cloudy eyes in betta, what causes them, and the ways to treat them, keep on reading this article.

What Is Betta Fish Cloudy Eye?

Betta fish cloudy eye is the eye disease that causes the lens of your betta to become opaque and cloudy, just like its name suggests. It is sometimes curable, but in extreme conditions, it can turn into cataracts in betta fish which can harm the fish and decrease its life expectancy. 

Finding The First Signs of This Disease

Many times, the first warning signs of disease in your fish appear first in its eyes, so it is very important to pay attention to the eye of the fish. If you don’t want a blind betta fish, you should immediately find the root cause and cure it while also making sure it doesn’t happen again.

Furthermore, the structure of the eye of betta is very similar to that of the human eye. There is a cornea which is the outer structure made to protect the internal structures. 

Behind the cornea is the iris, which adjusts the light coming into the eye, and the lens bends the light entering the eye. The betta fish white eye might be caused in the outer cornea layer or in the inner structure when their body fights infection. As you might have guessed, the inner cloudiness is much more dangerous.

Causes 

There are many causes for betta eye problems, and you have to find them out to prevent any other fish from suffering from this problem. Usually, this white eye is not a disease but rather a symptom that needs to be cured.

So here are some reasons for white eyes in your betta fish; just keep in mind that some of the symptoms are much more serious than others. If along with having an opaque lens, your fish also has difficulty swimming, finding food, and might prefer to stay hidden most of the time, then here are some reasons your betta has cloudy eyes.

  • Genetics

One of the reasons is genetics. This is, of course, irreversible since your fish was born this way. Saying that, this is not very common in betta fish.

To make sure betta fish’s white eyes are not genetic and so out of your control, check to see if the fish you bought has clear eyes. Some fish have cataracts genetically, so they have cloudy eyes; make sure to notice this before you purchase a betta fish.

Moreover, make sure to buy the fish from a reputable seller to have the best quality fish and avoid such an issue from the get-go.  

  • Physical Injury

This is one of the biggest causes of a white spot on betta’s eye. Physical injury is not only the biggest cause of cloudy eye in betta, but is also the biggest cause of damage in all fish. This is why it is so important to have a nice tank set up with no edges poking out or sharp plants.

If your betta has one cloudy eye, it is probably due to an injury. The physical injury could actually also be due to a scuffle with other fish in the tank. Usually, such a cause causes temporary betta eye problems that only exist on the outer cornea. 

This means that the eye will be okay by itself if the damage is not too grave and using eye drops is very unnecessary as it will wash away in the water anyway. In essence, it is important to find out how the betta got injured to prevent any future incidence.

  • Poor Water Quality

This is also one of the biggest causes of betta with the cloudy eye. Poor water quality is such a common cause because people don’t realize how even small water changes, especially in the pH of the water, can be so harmful to the fish.

Poor water quality occurs when the betta doesn’t have a big enough tank and filtration system. Many people assume that since bettas are so small in size, they don’t need a filter or proper water parameters.

This is very far from the truth; in fact, bettas produce a lot of waste. This waste accumulates in the water and changes the quality of water over time. 

Also, you have to ensure that the pH of the water does not fall below 6.8 as it can be deadly for the fish. If it does, having frequent partial water changes is essential until the water is of normal pH again.

If your fish has a bad eye due to water quality, it will go away as soon as you fix your water pH and other parameters. This is not permanent damage unless you fail to fix it as soon as you can.

  • Infection

If your betta has cloudy eyes due to infection, you should start worrying. This will need actual medical treatment and might be irreversible.

Many types of infections can lead to a blind betta fish or cause cataracts in betta fish if immediate actions are not taken. The infection might be a bacterial infection which is more common, or an internal parasite infection, which is much rarer and deadlier. 

The internal parasites are usually caused by a wild-caught fish or through live bait, and cannot easily develop in a home aquarium. You can also see the parasite through the cloudy eye, which is a very creepy view. Sadly, parasites can lead to a blind betta fish and this damage can never be reversed.

Furthermore, a bacterial infection is caused when your tank is dirty, and your fish gets injured by a said dirty object.

This is why everything in your tank needs to be super clean. This infection can easily be cured by medicine, and the damage is not permanent in most cases, thankfully. It can turn permanent if immediate actions are not taken, though.

  • Diseases

This cloudiness in the eyes of betta can also be a result of certain diseases that also affect humans. Sadly, once your fish develop these diseases, there is little to no way of curing the betta with cloudy eyes.

Cancer

The first disease is cancer. This is more common in fish living outside in the pond, but it can still occur in fish tanks. Cancer occurs when there is way too much UV exposure and a high level of metal contamination in the water, like lead and arsenic.

If your betta suffers from cancer, a tumor can grow in the eye, causing a cloudy experience. 

This can also cause serious neurological damage to the fish. The tumor is usually not removed unless it causes discomfort, in which case the eye has to be removed.

Cataracts

Another serious disease is cataracts in betta fish, which damage the lens of the fish. This is more common in fish that are old. Unlike cataracts in humans, there is no operation for fish eye cataracts. 

There are many reasons for this disease to develop, including parasitic infection due to flukes, genetic factors, incorrect feeding, and much more. Again this is irreversible, and your fish will just require extra care to survive.

  • Poor Nutrition

Like poor water quality, this is an avoidable cause of betta eye problems. A balanced diet with all the elements is very important for the health of betta.

If there is any dietary deficiency, especially a lack of vitamin A, there can be serious damage to the eye of your fish. Sometimes this can be difficult if your betta is a picky eater and has a favorite. 

To ensure all the nutrients are given to the fish, you will need to be more creative. A poor diet will make the fish more susceptible to bacterial and other infections, which can lead to cloudy eyes. If you start providing them with appropriate nutrients, they can be easily fixed.

How to Treat Cloudy Eye in Betta Fish

Once you know all the reasons for betta with cloudy eye, it is time to see how to solve this problem correctly. It is also important to take appropriate preventive measures so your fish never has to suffer from this issue again.

First of all, maintaining high water quality with partial water changes and an appropriate pH will cure the fish eye problems. Moreover, if you can, give your betta a proper diet containing high-quality flakes, pellets, frozen and dehydrated food items. 

Betta Fish Cloudy Eye Diseases, Treatments and Prevention

You should also look for the source of trauma if your fish has cloudy eyes due to that. Doing this will automatically cure the fish of any problems that it might have due to water and dietary issues.

If doing so still hasn’t fixed the eye issue, it is time to take the fish out in a separate quarantine tank and evaluate it properly. It is best to call your local vet at this point too. In this tank, add some salt to relieve stress in the fish. 

Provide the fish with a proper diet and maintain proper water conditions with partial changes. If the problem is serious, the vet will prescribe antibiotics that should be applied or given to the fish as per instructions.

Remember, even missing one dose of medicine can reverse all the progress you made, so follow the instructions carefully.

Preventive Measures

The best way to have healthy fish is by preventing the development of any disease in the first place. Remember, prevention is much better than cure. So here are some ways to maintain the health of your betta.

First of all, perform regular partial water changes; remember that a larger tank requires water changes less often than a smaller one. Moreover, test your tank every week to ensure ammonia and nitrate levels are as low as they need to be.

To keep your tank spotless and prevent bacterial infection, clean your tank once in a while by removing all items from it. 

Also, add some drops of solution in the water that will kill all bacteria. It is also important to have a good filter system and a water testing kit to maintain all necessary conditions. What’s more, don’t forget that stress can cause a lot of diseases and loss of appetite, so make sure to have a large enough tank for bettas.

Finally, you should always quarantine any new fish being introduced in the tank. This will reduce the chances of getting a parasitic infection, the worst cause for white eyes in betta. 

Following these instructions will ensure that the betta stays healthy and disease-free.

Can All Fish Get Cloudy Eyes?

Yes, there are a lot of fish along with betta that get cloudy eyes mostly fish that do not have eyelids. Some most known fish that suffer from this condition are bettas, fancy goldfish, and koi. Hence, you have to be careful with all the fish that you have. Actually, keeping pristine water quality in your tank is the best way to prevent betta fish white eyes.

Conclusion

Taking care of betta is not hard if you know what you are doing, and proper care will prevent the betta from developing white eyes. This problem is not contagious, so don’t worry if one of your bettas gets this issue; just try to fix it as soon as possible.

Furthermore, here is a summary of the most important points we discussed in this article:
