Peacock gudgeons are omnivorous and will readily accept a variety of live, frozen, and prepared foods. Their diet should consist of a balance of:

• Live foods: Brine shrimp, daphnia, mosquito larvae
• Frozen foods: Bloodworms, mysis shrimp, brine shrimp
• Prepared foods: High-quality flake food, pellets
