Since Goldfish are omnivouros, they can eat a wide variey of food such as brine shrimp, earth worms, lettuce, de-shelled peas, oranges, krill, daphnia, tubifex worms, elodea, duckweed, blood worms, and other shrimps. However, Goldfish flakes provide the important nutrients your goldfish needs on a daily basis. Other foods should be fed once or twice a week as a treat. Also, peas are very good for goldfish and solve most consipation issues.
