Common Causes & Solutions for Dragon Fish Pectoral Fin

Part 1: The Causes of Betta Fish's Bowed Mouth

Betta fish can exhibit a bowed mouth, which can be categorized into congenital and acquired forms.

Congenital bowed mouth is influenced by genetic factors and typically becomes noticeable as the fish grows to about 20 to 25 centimeters. Unfortunately, it is challenging to correct through dietary adjustments, so it's crucial to inspect the mouth shape of young bettas carefully when selecting them.

Acquired bowed mouth often relates to the fish's care routine. Since bettas swallow food by moving their jaws, as they age, the jaw muscles can become more pronounced, making the lower jaw slightly longer than the upper one. However, if the overbite is severe, it may require intervention through proper feeding and other measures.

Causes of acquired bowed mouth in bettas include:

Overly Large Food Portions: Many cases of bowed mouth are due to improper feeding. Feeding large pieces of food can make it difficult for bettas to chew and swallow, while overfeeding can lead to obesity and an overdeveloped lower jaw. Regularly feeding floating food or irregular feeding schedules can also exacerbate the issue.

Insufficient Tank Size: Bettas are active swimmers, and a cramped tank can lead to collisions with the glass, causing stress and difficulty in breathing. Over time, this stress can cause the lower jaw to grow upwards, resulting in a bowed mouth.

Stress and Scaring: Poor water quality or a noisy environment can cause significant stress, leading to collisions with the tank. This stress can result in jaw injuries and, subsequently, a bowed mouth.

Male Betta's Reproductive Mechanism: As male bettas mature, they naturally develop a bowed mouth. This is because they are responsible for mouth brooding the fry during the breeding process, and their jaws grow larger to accommodate more offspring.

1. Upgrade the Tank Size: Provide a larger tank to ensure a comfortable living space for your betta, preventing collisions and stressrelated issues.

2. Regulate Feeding: Feed your betta on a schedule, with portions that leave them 7080% full. Avoid long periods of fasting and overfeeding to prevent obesity and an overly developed lower jaw.

3. Keep the Environment Calm: Maintain a quiet environment to reduce stress and the likelihood of collisions or injuries.

4. Adjust the Diet: Serve smaller, but still manageable, food portions to encourage jaw movement and prevent overdevelopment. Ensure a varied diet and avoid feeding floating food consistently to minimize the risk of bowed mouth.

Severe bowed mouth can be challenging to correct, whether through feeding or surgery. It's important to accept the condition and focus on managing it. Mild cases, however, can often be improved. Fishkeepers should monitor their bettas' mouth shapes and adjust their care routines accordingly to say goodbye to the problem of a bowed mouth once and for all.
