Actinopteri (ray-finned fishes) > Acanthuriformes
(Surgeonfishes) > Chaetodontidae
Etymology: Chaetodon: Greek, chaite = hair + Greek, odous = teeth (Ref. 45335). More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 1 - 36 m (Ref. 1602), usually 1 - 5 m (Ref. 90102). Tropical; 30°N - 32°S, 43°E - 130°W
Indo-Pacific: East Africa to the Hawaiian, Marquesan and Tuamoto islands, north to southern Japan and the Ogasawara Islands, south to New South Wales (Australia) and Lord Howe Island.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 13.0 cm TL male/unsexed; (Ref. 9710)
Common in shallow exposed reef flats, lagoons, and seaward reefs; in relatively open areas with scattered corals and occasionally at depth of 36 m (Ref. 205). Benthopelagic (Ref. 58302). May be solitary or in small groups (Ref. 90102). Usually in pairs. Juveniles often in small aggregations and commonly mix with other similar sized juveniles, especially C. kleinii. Feed on small worms, small benthic invertebrates, coral polyps, and filamentous algae. Oviparous. 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).

Estimates based on models
Preferred temperature (Ref. 115969
): 25 - 29.3, mean 28.3 °C (based on 2407 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01465 - 0.03581), b=2.95 (2.82 - 3.08), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.3 se; based on diet studies.
Generation time: 0.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
