Actinopteri (ray-finned fishes) > Acanthuriformes
(Surgeonfishes) > Chaetodontidae
Etymology: Chaetodon: Greek, chaite = hair + Greek, odous = teeth (Ref. 45335). More on author: Bloch.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 20 m (Ref. 1602), usually - m (Ref. ). Tropical; 0°C - ; 31°N - 30°S, 52°E - 179°W
Indo-West Pacific: East Indies and the Philippines, through Papua New Guinea and the Great Barrier Reef to the Solomon Island, Palau, and north to China; extends into the Indian Ocean at least to the Maldives, India and Sri Lanka.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 12.0 cm TL male/unsexed; (Ref. 9710)
(total): 10 - 12;
soft rays: 14 - 17. White to yellowish below with 7 black stripes over head and sides, one centrally on snout and another as a strong black margin on end of dorsal and anal fins. Third line extends onto ventral fin (Ref. 48636). Snout length 3.0-4.1 in HL. Body depth 1.4-1.6 in SL (Ref. 90102).
Swim in pairs in coral rich areas of sheltered lagoon and inshore reefs; juveniles seen in groups among Acropora corals. Feed exclusively on coral polyps. Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Distinct pairing (Ref. 205). Monogamous mating is observed as both obligate and social (Ref. 52884).
