What do Ranchu goldfish eat?

Ranchu goldfish can eat animal-based feed, plant-based feed, and commercial feed. Animal-based options include brine shrimp, bloodworms, mealworms, yellow mealworms, daphnia, and water lice. Plant-based options include aquatic plants, algae, moss, tender vegetable leaves, and carrots.

Fry have higher nutritional needs, so during the juvenile stage animal-based feed can be the staple, paired with an appropriate amount of plant-based feed for balanced nutrition. Once adult, commercial pellets can become the main diet.
