Inhabits shallow coral reefs over coral, sand, rubble or seagrass substrata (Ref. 46844). Forms tight coherent schools when chased (Ref. 80499). Feeds on zooplankton and forms evasive, compact schools when threatened (Ref. 46844).
棲息於在珊瑚，沙子，碎石或海草下層土壤上的水淺珊瑚礁。 (參考文獻 46844) 當危險時吃浮游動物而且形成逃避又緊密的魚群。 (參考文獻 46844)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00451 - 0.02020), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.4 ±0.45 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.
