生物學特性     字彙 (例如 epibenthic)

Adults are found in lagoons, harbors, and coastal reefs, shallow habitats, deep sand or mud slopes with outcrops of debris or coral rubble pieces, or on rocky substrates in sheltered bays. They usually occur in large aggregations, sometimes forming mixed aggregations with Neopomacentrus sp. Abundant around sponge-encrusted mooring buoys and their anchor lines and occur in smaller colonies around rocks and refuse (Ref. 1602). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 113699).

發現於潟湖,港灣與岸礁了, 淺灘棲息地 , 和殘礫或者珊瑚殘礫塊的露頭深沙或泥斜坡,或在掩蔽的海灣的岩石的底部上。 通常一大群出現, 有時用 Neopomacentrus sp. 形成混合的群集豐富的在海綿的周圍鑲飾荒野浮標與他們的錨線的而且出現於在岩石的周圍更小的集群中並且拒絕。
