Masked Swallowtail Angelfish: The Elegant & Reef-Safe Angelfish

The Masked Swallowtail Angelfish (Genicanthus semifasciatus), also known as the Japanese Swallowtail Angelfish, is a peaceful and highly sought-after fish that serves as a graceful addition to any marine aquarium. Unlike many other angelfish, this species is a true planktivore and is considered reef-safe. This fish is known for its beautiful, elongated fins and its unique sexual dimorphism. Males have a pale body with faint vertical black or yellow bands, and a distinct dark mask-like pattern on their face. Females have a more uniform blue-white body with a black stripe on their dorsal fin. It is an active and graceful swimmer that requires plenty of open space to thrive. It is a fantastic choice for a well-established community tank.
