Darkstripe Tuskfish

Choerodon zosterophorus

Darkstripe Tuskfish are marine fish found in the Western Central Pacific, particularly around the East Indies and the Philippines. They inhabit tropical waters, preferring semi-open sandy substrates along reefs. These fish are often seen in deep channels and lagoons that experience strong tidal currents, thriving in environments where seawhips are abundant. Divers can expect to encounter them at depths ranging from 10 to 40 meters, although they are most commonly found up to 20 meters deep. The Darkstripe Tuskfish can be identified by its fusiform body shape and distinctive coloration. It has a broad pale band running from below the base of the last few dorsal-fin spines to the upper side of the pectoral-fin base. A large dark spot is situated dorsally on the side and on the ventral edge of the dorsal fin at the dorsoposterior end of the pale band. This dark spot usually extends as a tapering marginal band along the pale band. The caudal fin of adults is uniformly pale. These fish can grow up to 25 cm in length. Darkstripe Tuskfish are oviparous and exhibit distinct pairing during breeding. They are harmless to humans and currently listed as Least Concern by the IUCN. Divers might find them in areas with strong currents, making encounters dynamic and interesting.
