Foxfish are omnivorous fish and their food sources include plants, animal foods and artificial feeds. Foxfish like to eat small aquatic organisms such as small shrimps, small fish and plankton. These live foods are packed with nutrients and help your foxfish stay healthy. However, live foods may carry parasites or pathogens, so you need to make sure they come from a reliable source and are handled appropriately before use.

When feeding foxfish, you need to ensure that you are providing adequate nutrients to meet their needs for growth and maintenance of health. But feeding too much or too little can have negative effects on a foxfish's health. When feeding, ensure that the foxfish eats the feed within a few minutes to avoid waste and contamination of water quality.
