海葵Amphiprion clarkii(Bennett)的繁殖行为是在日本三宅岛描述的。寄主海葵属的海葵提供大小差异很大的筑巢栖息地，导致社会行为的差异。在大而拥挤的群体中，环境行为比只有一对优势鱼和2·`3条劣势鱼的小群体更明显。只有优势鱼具有性活动。求偶行为由雄性发起，仅包括清理巢，有时身体接触，并咬海葵的触须。摇头，背侧和腹侧倾斜，下巴点击，通常被描述为求偶行为，在这里被认为是激励性行为，在新建立的配对中发生的频率更高，在配对纽带较弱的情况下，比在已建立的“老兵”中更常见。产卵发生在上午9点·下午3点之间。雄性负责照看蛋的大部分，雌性很少扇蛋。除了孵化的晚上，夜间没有蛋的照看。蛋在日落后34·`70分钟之间孵化。
The reproductive behavior of the anemonefish,Amphiprion clarkii(Bennett)is described from the island of Miyake-jima,Japan.Host anemones of the genus Parasicyonis provide nesting habitats which vary considerably in size,resulting in differences in social behavior.Agonistic behavior is more pronounced in large,crowded colonies than in small ones with a single dominant pair and 2•`3 subdominant fish.Only dominant fish are sexually active.Courtship behavior is initiated by the male and consists merely of nest cleaning,sometimes with bodies touching,and nipping at the tentacles of the anemones.Head-shaking,dorsal and ventral leanings,and jawclicking,often described as courtship displays,are considered here as agonistic behavior,occurring more regularly in newly established pairs where the pair bond is weak than in established"veterans" . Spawning takes place between 9 AM•`3 PM.The male assumes most of the responsibility for egg-care,the female only rarely fanning eggs.Nocturnal egg care is lacking except on the night of hatching.Eggs hatch between 34•`70 min after sunset.
