Goldfish can eat crumbs of steamed buns, but you need to pay attention to the feeding amount. Steamed buns tend to expand in the goldfish's stomach. Overfeeding may lead to the death of goldfish. Moreover, steamed buns themselves lack other nutrients. Feeding them exclusively for a long time can cause goldfish to become malnourished and prone to diseases. Therefore, it is recommended to feed them in combination with fish food, fish worms, earthworms, etc., to ensure a balanced diet for goldfish.
Besides steamed bun crumbs, goldfish can eat a variety of foods. Goldfish are omnivores. Apart from fish feed, they can also eat millet, wheat grains, egg whites, lean meat, corn kernels, breadcrumbs, cookie crumbs, shrimp, egg yolks, noodles, vegetables, and other foods. These foods should be nutritious, clean, and hygienic, and small in size for easy digestion. It should be noted that the feed should not expand when it comes into contact with water, otherwise it may damage the fish's stomach.
