goldfish can eat millet grains and feed them once every two days. When feeding goldfish with millet grains, we should pay attention to changing water frequently and keep the water quality good at all times, because millet grains are very easy to destroy the water quality and cause pollution. In addition, there is no nutrition needed by goldfish in millet grains. Long-term use of millet grains to feed goldfish can easily lead to malnutrition and even illness. And millet grains are not digestible. If you feed rice grains, it is best to crush the rice grains first and match them with some other complementary foods, such as insects. Because the nutrition in rice grains can't satisfy goldfish. Therefore, we should take animal feed such as fish, insects and earthworms as our staple food.

goldfish eat live bait. For goldfish, live bait such as fish and insects is the best food, which can not only promote the growth of goldfish, but also be rich in protein, calcium, vitamins and other nutrients, which can meet the growth and development needs of this kind of fish. Fish and insects, also known as "Daphnia", belong to Cladocera or Flexible Foot, and are the best choice for bait. Fish and insects can live in fresh water, so they will not damage the water quality and absorb impurities such as organic matter in the water. Fish and insects are small in size and easy to digest, so they are the first bait for feeding goldfish. In addition to fish insects, you can also feed grain insects, earthworms, red worms, water earthworms and so on. When feeding, we should pay attention to nutrition collocation, feed regularly and quantitatively, and pay attention to controlling the food intake of each meal, so as not to let them eat.
