Description
The Barred Knifejaw is a robust marine fish characterized by its strong, beak-like mouth and prominent vertical black and white bands, which are more pronounced in juveniles. Native to rocky reefs of the Western Pacific, it is an active and powerful swimmer. This species requires a large aquarium and careful tankmate selection due to its size and potential territoriality.
