What do goldfish eat?

Goldfish are omnivorous, liking small aquatic animals and algae like daphnia, aquatic plants, and duckweed. For captive goldfish, use prepared feed as the staple with bloodworms, millet, rice grains, and bread crumbs.

Nutritional needs differ by stage; young goldfish need more high-protein food, so feed more animal feed. Adults do fine on pellet feed for balanced nutrition.
