生物学特性     字汇 (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).

栖息于岸边与外海的珊瑚礁。 (参考文献 9710) 也发现于港湾,舄湖与外礁斜坡。 缺乏一个大洋性的幼鱼时期的唯一的雀鲷科种。 鱼苗被由父母保卫的少许海洋的鱼之一.(参考文献 9710,48636) 鱼群当他们生长,而且亚成鱼通常被在小群鱼群中见到。 当繁殖的时候,成鱼形式配对而且是具有领域性。 (参考文献 48636) 一夫一妻的.(参考文献 52884)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

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。
