Description
Dorsal spines (total): 13-15 (usually: 14); Dorsal soft rays (total): 16; Anal spines: 3; Anal soft rays: 16-17; Pectoral fin rays: 16; Pelvic fin rays: I, 5; Lateral line scales: 33-36. Dorsal and anal fin scaled (except for distal margin of anterior spinous part). Anterior part of caudal fin scaled. Pectoral fin without scales. Caudal fin rounded in small specimens (< 35 mm SL) and subtruncate in larger specimens. Soft part of dorsal and anal fin rounded. Dorsal fin spines progressively longer posterior (last spine usually more than 3 times longer than the first spine), soft rays longer than spines. Pectoral fin slightly pointed, reaching a vertical above origin of anal fin. Pelvic fin pointed, elongate; filamentous tips reaching spinous part of anal fin. Body relatively flat and elongate; Body depth: 2.02-2.21 in SL, strongly compressed laterally; Dorsal contour more arched than ventral one. In frontal aspect with slightly keeled nape and somewhat flat chest. Caudal peduncle longer than high. Head short; Head length: 2.98-3.48 in SL and moderately deep. Snout shorter than interorbital width. Orbit situated below forehead contour, interorbital area convex. Mouth terminal, wider than high and wider than snout length. Jaw teeth slender, very elongate, slightly curved inward terminally, close-set, flexible, tricuspid (central cusp longer than lateral cusps); About 65 teeth in outer row in upper and in the lower jaw 55 respectively. A large, elongate horizontal spine at ventro-caudal corner of preopercle, another much smaller spine on anteroventral margin of preopercle and 12-18 much smaller spines on upper caudal margin of preopercle. Anteroventral margin of preorbital with 2 very stout spines, in larger specimens (> 45 mm SL) sometimes with an additional third smaller spine. Max. length: 7.5 cm TL. Depth range: 10 - 95 m, usually: 24 - 60 m.
Color
Variable ranging from a dark purplish-black over head, body and median fins, to dusky orange on head, chest, dorsal and anal fins fading to orange-brown centrally on body; Dorsal and anal fins with a narrow blue margin; Posterior part of dorsal and anal fins with narrow alternating blue and black (or blue and orange) markings; Paler individuals with a dark blotch anteriorly on side of body, dorsal to pectoral fin and posterior to operculum; Pectoral fins transparent; Pelvic fins ranging from black to yellow with a blue pelvic spine; Caudal fin a translucent yellowish.
Etymology
Centropyge: from Greek, kentron = sting + from Greek, pyge = rump, buttocks, tail. Referring to his three anal-fin spines.
fisheri: named for Walter Kenrick Fisher (1878-1953), American zoologist, specilized in echinoderms.
Original description: Holacanthus fisheri Snyder, 1904 - Type locality: off Diamond Head, Oahu Island, Hawaiian Islands, depth 27-29 fathoms.
Distribution
Indo-West Pacific: East Africa, Mauritius (Mascarenes) and Maldives east to Hawaiian Islands, Marquesas Islands and Tuamotu Archipelago, north to southern Japan, south to Western Australia, New South Wales (Australia), Chesterfield Islands, New Caledonia and Tonga.
Biology
Benthopelagic species found in reefs, in coral bottoms of channels and over reef slopes; Also in areas with rubble bottom. Often in small loose groups on inner reefs in low patches of brittle corals and coralline algae mix that is shared by damselfishes and small wrasses. Herbivorous feeds on algae. Occasionally exported through the aquarium trade. Bi-directional sex change has been confirmed for this species.
