Lovely fish, Murfman! I thought dussumieri tangs have a white caudal spine?
this come from here;
Eyestripe Surgeonfish, Pencilled Surgeonfish, Acanthurus dussumieri
Description:
The Eyestripe Surgeonfish or Pencilled Surgeonfish are highly variable in color depending on the locality where each fish is found. The body can range from a grayish color to a Hawaiian variety that has yellow around the edges of the body with purple highlights. They have thin wavy lines on the face and gill cover, and an orange band over the eyes. A Great Barrier reef version sports irregular blue lines and a yellow head with more blue spots and lines. The caudal fin is blue with dark spots, sometimes with a lighter yellow area at the base, and is moon shaped in adults. On each side of the caudal peduncle is a single spine or scalpel, covered with a whitish sheath on a black patch. Juveniles are usually not as colorful as adults. They have a dusky colored body, yellowish dorsal fins, and the base of their caudal fin is whitish. This species can live up to 28 years.
The characteristic yellow band through the eye can also be seen on some very similar species, the Ringtail Surgeonfish A. blochii, Elongate Surgeonfish, A. mata, and Yellowfin Surgeonfish A. xanthopterus. But the Eyestripe Surgeonfish can be distinguished from these others by the dark spots in the center of its caudal fin and the lack of a yellow edge on its pectoral fins.
