Common name: Swallowtail Angelfish

Genicanthus is a genus of marine angelfish known for their distinct sexual dimorphism and elongated finnage. Members of this genus, such as the popular Genicanthus lamarck, are unique among angelfish for their planktivorous diet, making them less likely to nip at corals, which is a common concern with other angelfish. They are generally peaceful and can be kept in pairs or harems in larger aquariums. Their graceful swimming and striking patterns make them a favorite among aquarists.
