背棘 (總數) : 7; 背的軟條 (總數) : 10 - 12; 臀棘: 1; 臀鰭軟條: 9 - 10; 脊椎骨: 26. Two oblique pigment bars on the head posterodorsal to the eye.

Facultative air-breathing in the genus (Ref. 126274); Found in association with Acropora loripes and Acropora elseyi; commonly in pairs (Ref. 36585); a coral-commensal species (Ref. 72446). Feeds on copepods, forams, and unidentifiable flocculent material (may represent in part the remains of coral tissue) (Ref. 36585).

發現於鄰近 Acropora loripes 與 Acropora elseyi; 通常成對。吃橈腳類的動物，有孔動物與無法辨認的叢毛狀的材料 (部份地可能是那珊瑚組織保持) 。 (參考文獻 36585)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

營養階層 (Ref. 69278): 3.3 ±0.25 se; based on food items.

回復力 (Ref. 120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
