This species will feed mostly on suspended prey in the water column, but has also been known to pick food off the substrate. Its diet should consist of a variety of chopped or shaved seafood, vitamin-enriched brine shrimp, and mysis shrimp to ensure it is receiving the proper nutrients. Furthermore, it is important to feed the Helfrichi’s Firefish multiple small meals throughout the day to keep it healthy. Additionally, regular water changes of 10%-15% should be done to maintain water quality.
