In the wild, the Reunion Angelfish feeds on sponges and tunicates. In captivity, they should be offered a varied diet that includes high-quality marine angelfish preparations, enriched brine shrimp, mysis shrimp, and finely chopped seafood. Providing a balanced diet with plenty of marine-based proteins will help maintain their health and vibrant coloration.
