The koi may die. Under normal circumstances, they will not be stuffed to death. Because they know hunger and satiety, they will stop eating on their own initiative when they eat too much food. Moreover, although Koi have a strong desire to eat, they do not have the ability to eat food. If you eat too much food and can't digest it, the koi will spit it out automatically.
However, the quality of feed in the market is uneven, and some fish friends may choose inferior feed in order to be cheap. Inferior feed is mostly dry feed, this kind of feed, Koi do not feel when eating, but in the water, food will expand in the stomach, it is easy to support the stomach of Koi, so that it died. Therefore, the feed should choose a trustworthy brand. For the healthy growth of Koi, it is better to feed small fish, shrimp and other foods at ordinary times, which are easy to digest, nutritious and will not swell.
? Koi fish will freeze to death. Although Koi can survive at 5-30 degrees Celsius, it will freeze to death when the temperature is too low. When the water temperature is below 0 ℃, it will stimulate the mucosa of the koi. The existence of the mucosa can protect the koi. Once the mucosa is destroyed, the koi will easily die. If you want Koi to grow healthily, the water temperature should be stabilized at 20-25 C. When the temperature is low, it should be warmed up in time.
