一夫一妻制的德克萨斯慈鲷（Cichlasoma cyanoguttatum）的父母双方都参与照顾后代和领土防御。这些活动通常是同步的，有或没有入侵者存在，使得只有一个父母远离后代。在卵和蠕虫阶段，雄性花更多的时间巡逻领土，而雌性花更多的时间照顾后代。在鱼苗阶段，父母双方都倾向于和后代呆在一起。任何一种性别都可以在没有配偶的情况下抚养后代。在失去配偶的情况下，雌性的活动基本上保持不变，而雄性（在没有雌性的情况下）变得像雌性一样。看起来好像雄性会根据雌性的活动来调整自己的反应。
Both parents of the monogamous Texas cichlid (Cichlasoma cyanoguttatum) participate in offspring care and territorial defense. These activities are typically synchronized, with and without intruders being present, such that only 1 parent is away from the offspring. During the egg and wriggler stage, the male spends more time patrolling the territory while the female devotes more time to offspring care. During the fry stage, both parents tend to remain with the offspring. Either sex can rear the offspring in the absence of the mate. With the removal of the mate, the female''s activities remain largely unchanged while the male (in the absence of the female) becomes female-like. It appears as if the male adjusts his responses according to the activity of the female.
