Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 3 - 30 m (Ref. 89972). Tropical; 37°N - 32°S, 95°E - 134°W
Pacific Ocean: widespread from Japan and Australia to the Tuamoto Islands and Hawaii. Replaced by Chaetodon trifasciatus in the Indian Ocean (Ref. 37816). DNA (from tissue samples) expected to further distinguished Chaetodon lunulatus and Chaetodon trifasciatus (Ref. 86689).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 14.0 cm TL male/unsexed; (Ref. 48636)
Occur in monogamous pairs in coastal coral-rich areas (Ref. 47838, 48636). Juveniles hide among branches of small corals, often in lagoons (Ref. 9407). Benthopelagic (Ref. 58302). Feed solely on live corals (Ref. 47838). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 29.3, mean 28.3 °C (based on 1779 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02291 (0.01123 - 0.04674), b=3.00 (2.83 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.61 se; based on food items.
Generation time: 0.6 ( 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) .
