金鱼最好几天喂一次。因此，不同年龄的金鱼每天需要在不同的时间喂食。它们吃得更少，因此在生长阶段需要多次喂食，以确保它们能够正常发育。在幼年阶段，它们需要每天喂食两次

成年金鱼可以每天喂食一次，每次4-5粒。如果鱼不饿，可以调整为每2-3天喂一次。金鱼可以忍受饥饿，如果它们长时间不进食也没关系。如果你喂得太多或太频繁，金鱼很容易死亡。如果你喂得太多，你需要及时清理水中多余的食物，以防止它们污染水质

It is best for goldfish to feed once a few days

The speed of goldfish's digestion will change with age. Therefore, goldfish of different ages need to be fed at different times every day. They eat less, so they need to be fed several times during the growth stage to ensure that they can develop normally. In the juvenile stage, they need to be fed twice a day

Adult goldfish can be fed once a day, 4-5 fish grains each time. If the fish is not hungry, it can be adjusted to feed once every 2-3 days. Goldfish can endure hunger, and it is fine if they do not eat for a long time. If you feed too much or too often, goldfish will easily die. If you feed too much, you need to clean up the excess food in the water in time to prevent them from polluting the water quality
