There are many reasons why betta fish don't eat feed. When they find that they don't eat feed, they need to find relevant reasons and treat them:

1. Adjust water temperature: They don't eat feed may be because the temperature is not suitable. When the temperature in the fish tank exceeds 28 ℃ or is lower than 18 ℃, it will affect their body activity and then affect their appetite. In this case, the water temperature should be adjusted to 22-24 ℃.

2. Treatment of enteritis: It may also be indigestion caused by eating too much. At this time, a small amount of enteritis spirit can be dissolved in water to promote their digestion. When the food in the stomach is completely digested, they will slowly regain their activity.

3. Change food: It may also be because the food you feed is not suitable. When they are fed food they don't like or food they often eat, they may refuse to eat. At this time, they can be fed some favorite foods, such as live bait, to improve their diet and increase nutrition.

Betta fish eat support, and if they are fed too much, they will eat support easily. When they are fed bread, steamed bread and other foods that swell with water, they may also eat too much. When they eat, their stomachs will swell and they don't like swimming. They are being fed at this time, and they will spit out the food. There are also a small number of fish that will become swollen and lose their balance slowly after eating. When they eat, they don't need to continue feeding them. If they are fed again, they will easily suffer from enteritis.
