More about Japanese swallow angelfish
The Japanese swallow angelfish (Genicanthus semifasciatus) is a marine fish characterized by its unique coloration; males are a blend of blue, black, and white, while females are predominantly white with a black stripe. Originating from the Western Pacific, particularly around Japan, this species is distinguished by its elongated, swallowtail-like caudal fins. Despite its visually appealing appearance, it is not among the most common species in the aquarium hobby, in part due to its regional specificity and care requirements.
