Betta Cloudy Eye Guide: Causes, Symptoms & Treatment

Is your Betta acting strange lately? Is it strange that it keeps banging into the tank or its tank mates as if he can’t see? This indicates that your betta’s eyes are fuzzy, or should I say cloud. This is a common betta condition that may be cured if caught early enough and with the proper medicine.

Even though this sickness is simple to treat, some individuals are irresponsible, and postponing treatment might result in your betta’s death. So you don’t have to do that; instead, take it seriously and deal with it promptly.

Betta’s cloudy eye is a disease in which the lens of Betta turns opaque or blurry. There are many causes of this disease i.e. infections, poor water quality, chemicals in water, poor nutrition, stress, injury, or old age.

As a result, this guide has been particularly created to provide every detail about the condition. It outlines all of the actions you must follow to properly treat your betta. So, without further ado, let us begin.

What does a cloudy eye mean?

A hazy eye is a condition that causes your betta’s lens to become cloudy and opaque. However, because hazy eyes can have a variety of reasons, it’s critical to have the right diagnosis for the best therapy.

Your Betta’s Eye Movements

The eyes of your betta friend operate similarly to the eyes of most creatures:

  1. The eye receives light.
  2. The pupil concentrates light.
  3. The light strikes a receptor, which generates an image.
  4. The fish’s brain interprets the image.

The specific gravity of water differs from the specific gravity of air. As a result of its adaptation to living underwater, a fish cannot see clearly outside of the water. Betta fish have eyes on the sides of their heads, allowing them to see to each side of their bodies, virtually straight behind and in front of them. However, the fish’s inability to understand two independent pictures at the same time indicates that it lacks depth awareness. The majority of fish species, including bettas, lack eyelids. This might cause harm to their eyes, which is one of the main reasons why you should never put sharp things in your betta’s tank.

Predatory fish like bettas require a certain level of depth awareness in order to view their prey properly. To compensate, the betta’s eyes are positioned somewhat further forward on his head. Using two nets and coming from two separate directions at the same time, you may take advantage of the fish’s poor depth perception.

Blindness in wild bettas is fatal for the fish since it prevents them from hunting and finding food. Obviously, this does not apply to your betta in a tank, however, you may need to hand-feed him to ensure that he gets enough food.

What causes cloudy eyes in Betta Fish?

Cloudy Eye in fish has a wide range of reasons.

1. Internal Parasitic Infections

Internal parasites, such as flukes and protozoa, can sometimes attack your betta. These parasites normally infect wild fish, but they might end up in your home aquarium if they catch a trip on plants or on live food. As a result, you should always wash whatever you add to your aquarium in an antibacterial and antiparasitic solution before putting it in.

Infected fish acquire clouded, enlarged eyes, which can sometimes include tiny worms. Affected fish typically lose vision in one eye and may develop a cataract in that eye.

Unfortunately, while you may treat the aquarium water to eradicate the parasites, your betta will stay blind once the harm has been done.

2. Cataracts

Fish, like humans and other pets, can get cataracts. Cataracts are a common eye ailment that causes the lens of the eye to become opaque and hazy, especially in older bettas.

Parasites (see above), hereditary causes, or improper diet can all induce cataracts. Cataracts in fish do not respond to therapy.

3. Infection With Bacteria

It’s critical that your betta’s tank be free of sharp or abrasive things. Smooth tank decorations are preferred over plastic, and if you don’t use real plants, soft silk plants are preferred over plastic. For your curious betta, everything pointy is a potential source of damage.

Injuries to the eyes are a common entrance route for germs, which can create an infection and result in permanent eye damage, vision loss, and cloudiness. If you catch the injury early enough, you might be able to salvage your betta’s sight. To heal the illness, place your wounded betta fish in a quarantine tank and treat the water with a unique antibiotic.

4. Nutritional Deficiencies

Your betta has to consume a well-balanced diet if you want him to be healthy, lively, and flourishing. Any dietary deficiencies, such as a vitamin A deficit, might injure the eyes of your fish.

As a consequence, offer your betta a well-balanced diet of high-quality tropical flakes, betta micro pellets, frozen meaty feeds, and dehydrated freeze-dried blood worms.

5. Poor Water Quality

But the most important thing to remember is that poor water quality will be the root of most of these problems.

The solution is straightforward: test the water in your aquarium on a regular basis. If the pH goes below 6.8, increase the frequency of water changes and test the water every day for a few days to ensure the pH remains stable. You should also test your tap water before putting it in your tank, as you might need to add a pH buffer as well as a de-chlorinator.

After the low water quality issue has been resolved, your fish’s eye condition should clear itself without any more intervention or permanent injury.

The emergence of a grey or opaque film over your betta fish’s eye or eyes is the major sign of a Cloudy Eye. In response to the infection, you may see a build-up of mucus on the fish’s body.

What Causes Cloudy Eyes In Betta Fish

Your betta may have trouble swimming and obtaining food, and he may lose his appetite as a result. Your fish may also grow anxious as a result of his situation and lounge about on the substrate or hide in a cave.

It might be another condition if you detect any other symptoms in addition to blurry eyes. Cloudy eyes, for example, are a common sign of Popeye. You should not treat your betta for clouded eyes if you observe his eyes popping out.

How do you treat a Betta’s eye cloud?

First and foremost, if your betta fish is housed in a tank with other fish, you should relocate him to a quarantine tank.

You should add a little amount of aquarium salt that you’ve already dissolved in a small tank of water once the fish has been transferred to the quarantine tank. One spoonful of salt per five liters of water is required. Add some stress coat water conditioner as directed by the manufacturer to assist your pet to relax and building up his slimy coat. When doing partial water changes, remember to replenish the stress coat and salt.

While your betta is in the hospital tank, do several partial water changes in your main tank. The more aquarium space you have, the less water you’ll need to refill. Change half of the water in your 5-gallon betta tank every three to four days. If the tank is 10 gallons, only replenish 25% of the water every three to four days. When your fish shows signs of recuperation, you can restore him to the main aquarium.

Malnutrition Causes Cloudy Eyes

If you believe your betta’s foggy eye is due to starvation, you should still follow the measures outlined above. But, on top of that, you should make sure he’s getting plenty of vitamins and nutrient-dense meals. A fantastic option is always live food. Once a week, add blood worms, daphnia, and mosquito larvae to your aquarium. Additionally, you should ensure that you are purchasing high-quality pellets for your betta.

How can you prevent cloud eyes in your Betta?

The simplest way to prevent cloudy eyes in your betta is to maintain adequate water quality in your tank. Keep ammonia and nitrite levels below 0 ppm and nitrate levels below 20 ppm to improve water quality. Here are some possibilities to consider:

Check the water in your aquarium at least once a week. Both ammonia and nitrite levels should be zero, with nitrate levels not exceeding 20 parts per million (parts per million). If the levels rise, make a partial water change to correct the situation.

Make careful to change the water once a week and vacuum the gravel to eliminate any fish waste, uneaten food, or other debris.

How Can You Prevent Cloudy Eyes In Your Betta

Remove all decorations, including silk plants, on a regular basis and clean them carefully. Use a high-quality filtration system to maintain your tank clean and the water quality in your pet’s house good. Mechanical, biological, and chemical components should all be present in the system. The mechanical filter gathers floating debris, the biological filter processes fish waste, and the chemical filter filters heavy metals and other chemical poisons out of the water.

Replace the cartridges as needed and clean the filter once a month. Overstocking your tank might put a strain on the filtering system. The standard is one inch of fish per gallon of water.

Keep your betta in a vase or aquarium with a minimum capacity of 5 gallons. The water will quickly get contaminated, the pH will most likely fluctuate, and your pet may have health problems as a result. Feed your betta a well-balanced, healthful diet with enough meaty protein.

Is cloud eye highly contagious?

A betta with a hazy eye can’t transmit it to other fish, therefore it’s not contagious in that sense. However, the same factors that create foggy eyes in one fish are likely to cause it in another. If you notice several fish in your tank, you’ll need to take immediate measures to improve the water quality. Remember that foggy eyes might be a sign of malnutrition or a sign of other, more serious conditions.

Is cloud eye a deadly condition? Is it Fatal?

Any ailment that betta contracts can be lethal if it is left untreated. A hazy eye, on the other hand, is less likely to be lethal on its own. As long as you cure your betta and modify the water, he should bounce back quickly. This is a different story if you discover the symptoms are growing worse or if you see more symptoms. If this is the case, you should seek treatment at your local aquatic facility. While a foggy eye on its own is unlikely to be lethal, it might be if it is an indication of something worse.

The Bottom Line on Betta Cloudy Eye Guide

If your betta fish has Cloudy Eye, start by doing a water test to determine the source of the problem. If the water conditions in the aquarium aren’t up to standard, make a partial water change to correct the problem. Put your betta in a hospital aquarium and treat him with aquarium salt and slime coat while you’re treating the tank.

Some forms of Cloudy Eye are incurable, and your fish will most likely go blind. The most common cause of this unpleasant disease is poor water quality, which is easily avoided by keeping your aquarium clean and well-maintained.
