First, goldfish may have digestive problems or gastrointestinal diseases. In this case, stop feeding the goldfish and observe its activities closely. Once other abnormal conditions occur, it is necessary to make reasonable diagnosis and treatment, and do not delay the treatment time of goldfish.

Second, goldfish will spit out the food they eat. Maybe it's not hungry, but its stomach is still full. In this case, you can look at the fish's belly carefully first to see if it is bulging and round. If so, you can also temporarily stop eating a few meals and feed the goldfish new food after the food in the body is completely digested and decomposed.

Third, the goldfish spit out the food, or it may be because the bubbles were swallowed when eating, which caused the stomach to hold the rest of the food and had to spit it out. In this case, we should stop eating first and then observe the goldfish closely. As mentioned above, once the abnormal situation occurs, it must be dealt with as soon as possible, otherwise the goldfish may die.

Fourth, the goldfish spit out the food, which may be that the prepared food is not suitable. The food block is too big for goldfish to eat normally. Then before feeding, the breeder had better make the food as small as possible, and then give it to the goldfish to avoid the problem of goldfish spitting again.

Goldfish can't eat:

1. Goldfish is a variety of crucian carp, which is the product of genetic variation. During the Sui and Tang Dynasties in ancient China, goldfish were already kept in ponds. Then it began to spread abroad in the Ming Dynasty, 1502 to Japan, 17 to Britain at the end of the year, and 19 to the United States at the beginning of the year. Scientists at home and abroad have published a large number of works on the formation process and factors of goldfish varieties, confirming that goldfish is a typical mutant variety produced under domestic conditions, and the reason for not eating goldfish lies in people's concern about genetic mutant varieties.

Goldfish has always been loved by people because of its beautiful appearance. The ornamental value of goldfish is much higher than its edible value. In the long river of time, goldfish has been endowed with many beautiful meanings by China, such as: more than one year, beautiful, auspicious, safe and so on. Ornamental fish, such as goldfish, have evolved into many kinds after several generations of cultivation, which can be roughly divided into three categories: literary species, dragon species and grass species. After human cultivation, goldfish itself contains many factors such as culture and emotion, so it is not included in people's recipes, just as people usually don't eat it after their beloved dog dies.

3. Goldfish is cultivated artificially in a small water body. The fish is not very good, but it tastes bad.
