Causes of Dragon Fish Bulging Eyes: What's Behind the C

There are numerous factors that can lead to a Betta fish developing bulging eyes. These include high levels of nitrites in the water, improper feeding, bacterial or parasitic infections, and more. When a Betta exhibits symptoms of bulging eyes, it is crucial for the keeper to take immediate notice and implement the right measures. Below, we delve into the causes of bulging eyes in Betta fish and how to address them effectively.

Causes and Solutions for Betta Fish Bulging Eyes

1. Aging Water Quality: When water becomes too old, it tends to have higher levels of nitrites, which can easily infect a Betta's eyes, leading to bulging eye disease.

Solution: If the bulging eyes are due to high nitrite levels, the keeper must act promptly by changing the water, running the filter continuously to prevent water degradation, and reducing nitrite levels. Maintaining clean and fresh water is essential for the Betta's health, so regular water changes are a must.

2. Incorrect Feeding: Betta fish can also develop bulging eyes if they are overfed with highprotein foods. Excessive protein intake combined with low activity levels can lead to fat accumulation and bulging eyes.

Solution: To address this, the keeper should adjust the Betta's diet to include lowerprotein foods and reduce the amount of protein given. Installing a wavemaking pump in the tank can also encourage more activity, which can help alleviate the bulging eyes over time.

3. Bacterial or Parasitic Infections: Bulging eyes can also be a result of infections following an injury. If a Betta's eye area is injured and becomes infected, the eye may bulge due to the infection.

Solution: In case of an eye infection, the keeper should change the water to reduce bacterial growth and treat the Betta with appropriate medication. The injured Betta should be removed from the tank, and eye drops should be administered to the affected eye to combat the infection and promote healing.

In addition to these, factors such as rising pH levels, high alkalinity, vitamin B deficiency, and exposure to intense light can also cause bulging eyes in Betta fish. Therefore, when a Betta shows signs of bulging eyes, the keeper should closely monitor the fish's health and the tank's water quality to identify the specific cause and treat it accordingly.

With timely treatment, Betta fish with bulging eyes can usually recover quickly. High nitrite levels in the water are preventable, so regular water changes are vital to maintain good water quality. This helps dilute harmful substances and is a key preventive measure against various diseases. Additionally, the keeper should feed the Betta a balanced diet to avoid oversupplementing with protein. In the early stages of bulging eyes, the keeper can try升温 (raising the temperature), 下盐换水 (saline water changes), and老三样 (the three old methods) treatments, as well as strengthening the filtration system. In severe cases, adding nitrifying bacteria to the water can help reduce harmful residues. Typically, the Betta's eyes will return to normal quickly. However, if the bulging eyes are due to dietary issues or bacterial infections, targeted treatment is necessary.

Understanding the causes and solutions for Betta fish bulging eyes is essential. Keepers should always prioritize maintaining good water quality and feeding their Betta fish properly to prevent such issues.
