专性生活在珊瑚中的鹰鱼被认为是一夫一妻制的。这种假设的交配系统与已知的其他胆管虫的交配系统不一致。研究人员对栖息在柳珊瑚和反帕拉珊瑚中的红珊瑚和尖角红珊瑚进行了检查，以寻找一夫一妻制交配系统的证据。对这两个物种有利于珊瑚礁鱼类一夫一妻制的生活史标准（Barlow 1986）进行了检查。两者都存在兼性一夫一妻制。在这种交配系统中，雄性获得和维持雌性的能力有限，因此只有一个配偶，但如果条件有利，可能会获得更多的雌性。
Obligate coral-dwelling hawkfishes have been hypothesized to be monogamous. This hypothesized mating system is at odds with what is known of those of other cirrhitids.Neocirrhites armatus, which inhabitsPocilloporaspp. corals, andOxycirrhites typus, which inhabits gorgonians and antipatharian corals, were examined for evidence of a monogamous mating system. Life history criteria that favor monogamy in reef fishes (Barlow 1986) were examined for these two species. Facultative monogamy was found in both. In this mating system, males are limited in their ability to acquire and maintain females, and thus have only a single mate, but may acquire additional females if conditions for doing so are favorable.
