In the wild, the Japanese swallow angelfish is found in coral reefs and rocky areas, where it feeds on algae and small invertebrates. It is a peaceful fish that can be kept in a community aquarium, but it should not be housed with aggressive fish or other angelfish, as it may be bullied.

Its diet should consist of a variety of meaty foods, such as frozen shrimp and squid, as well as vegetable matter, such as spirulina and nori.
