1. Animal feed: goldfish belong to omnivorous fish, and their food requirements are not high, and there are many kinds of food that can be eaten. Breeders can choose animal feed as their staple food when feeding, and the animal feed suitable for them to eat includes bumper shrimp, earthworm, water flea, water earthworm, red worm, bread worm, yellow mealworm, lean meat, animal viscera and so on. These foods contain more protein and fat, which is of great help to their growth and development.

2, plant feed; Breeders can also match them with some plant feeds, such as tender leaves of vegetables, apples, bananas, cantaloupe, moss, aquatic plants, rice, bread crumbs and so on. This can ensure the diversity of their food and the balance of their nutrition.

3. Synthetic feed: Many breeders don't have time to make these feeds, and they can choose synthetic feed as their staple food. However, the nutrition of synthetic feed is not sufficient, so breeders need to feed some animal feed regularly to supplement nutrition.

The feeding frequency of goldfish is different at different growth stages. Juvenile goldfish can choose to feed twice a day, and the amount of each feeding can be finished within 3 minutes. As an adult, you can feed it once a day, and the amount of each feed can be eaten within 5 minutes. If the temperature is low, you can choose to feed it once every 2-3 days.
