生态学
海洋 礁区鱼类; 深度上下限 ? - 30 m (Ref. 86942). ; 30°N - 30°S
Indian Ocean: from East Africa and islands of western and central Indian Ocean to Andaman Sea, Cocos-Keeling Islands, Christmas Island, and western Indonesia (western Sumatra, Java, Bali ad Nusa Penida).. According to Randall, pers. comm. 1995 Chaetodon trifasciatus occurs only in the Indian Ocean while Chaetodon lunulatus occurs only in the Pacific). DNA (from tissue samples) expected to further distinguished two distinct species (Chaetodon lunulatus and Chaetodon trifasciatus (Ref. 86689).
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 13.8, range 13 - 15 cm
Max length : 15.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5372); common length : 12.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5450)

Occur in coral-rich lagoons and semi-protected seaward reefs. Territorial and aggressive to other Chaetodon. Small juveniles secretive in corals (Ref. 48636). Swim in pairs. Feed exclusively on coral polyps, particularly of the Pocillopora type (Ref. 5503, 48636). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01585 - 0.03467), b=3.06 (2.94 - 3.18), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.3 ±0.6 se; based on diet studies.
Generation time: 0.8 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (K>1).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 141 [69, 248] mg/100g; Iron = 1.12 [0.63, 2.02] mg/100g; Protein = 18.7 [17.5, 19.9] %; Omega3 = 0.116 [0.061, 0.225] g/100g; Selenium = 44.1 [20.8, 94.0] μg/100g; VitaminA = 29.6 [7.5, 114.6] μg/100g; Zinc = 1.73 [1.09, 2.68] mg/100g (wet weight);
