生物學特性     字彙 (例如 epibenthic)

Adults inhabit inshore and offshore coral reefs (Ref. 9710). Also found in harbors, lagoons and outer reef slopes. The only pomacentrid species that lacks a pelagic larval stage. One of the very few marine fishes where fry are guarded by the parents (Ref. 9710, 48636). School as they grow and sub-adults are usually seen in small groups. Adults form pairs and are territorial when breeding (Ref. 48636). Monogamous (Ref. 52884). Oviparous (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

棲息於岸邊與外海的珊瑚礁。 (參考文獻 9710) 也發現於港灣,潟湖與外礁斜坡。 缺乏一個大洋性的幼魚時期的唯一的雀鯛科種。 魚苗被由父母保衛的少許海洋的魚之一.(參考文獻 9710,48636) 魚群當他們生長,而且亞成魚通常被在小群魚群中見到。 當繁殖的時候,成魚形式配對而且是具有領域性。 (參考文獻 48636) 一夫一妻的.(參考文獻 52884)

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

Oviparous, distinct pairing during breeding (Ref. 205). Monogamous mating is observed as both obligate and genetic (Ref. 52884). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Does not have a juvenile bisexual phase and all males have the typical testicular morphology of gonochores (Ref. 103751).西太平洋: 印尼與菲律賓到澳洲東北方與美拉尼西亞。
