1. Newly bought koi will start feeding in a few days Newly bought koi will start feeding in three days. The reason why we have to wait for three days is that the newly bought fish will be affected by environmental changes, become a little nervous and don't eat much. It is useless to feed at this time, and it will pollute the water, stimulate the fish and even produce stress reaction. So you need to rest for a few days. After three days, the fish can get used to it and start feeding.
2. What food to feed koi fish1. Animal feed: Animal feed mainly includes fish insects, Cyclops, water earthworms, paramecium, wigglers and so on. This kind of food can survive for a long time in the fish tank, which can stimulate Koi's interest in eating. This kind of feed also contains a lot of protein, vitamins and other nutrients, which can promote the hair color and growth of koi.
2. Plant feed: Koi fish has a miscellaneous diet. Besides animal feed, it can also eat plant feed, such as weeds and aquatic plants, but don't use it as a staple food, because long-term feeding of plants may lead to stunting of fish.
3. Synthetic feed: Synthetic feed is rich in protein, sugar, vitamins, inorganic salts and fat, which can ensure the normal growth of koi. Eating these foods can also enhance the resistance of koi fish, so that they are not easy to get sick. Furthermore, eating this kind of food will make koi fish's hair color more uniform and make their gonads develop more soundly.
