The removal of a single dominant individual has been shown to trigger a sex change in some coral-reeffish. In the saddleback wrasse (Thalassoma duperrey), however, female-to-male sex change requires visual stimulation from smaller conspecifics. This change is not dependent on the sex or color of the stimulus fish and can be inhibited by larger conspecifics. On the reef, a female probably changes sex when the relative numbers of larger and smaller conspecifics change within her home range.
研究表明，去除单一占主导地位的个体可促使某些珊瑚礁鱼类发生性别转变。然而，对于鞍背濑鱼（杜氏海猪鱼）而言，从雌到雄的性别转变需要来自较小同种个体的视觉刺激。这种转变并不取决于刺激鱼的性别或颜色，且会受到较大同种个体的抑制。在珊瑚礁上，当雌鱼活动范围内较大和较小同种个体的相对数量发生变化时，它可能会改变性别。
