Cichlid fish exhibit a complex behavioral repertoire, mainly regarding social and reproductive behaviors. Nevertheless, although dwarf cichlids exhibit a remarkable diversity of behaviors, only a few studies have been conducted with these fish. Apistogramma trifasciata is a common dwarf cichlid in the Neotropics and widely used as ornamental fish. Both males and females are territorial and engage in biparental care. Here we observed the behavior of A. trifasciata males and females to construct an ethogram. We registered the parental care of a couple since the spawn until the moment when the offspring became independent. Striking behaviors were observed, such as male-male contests involving circling displays and mouth wrestling, and parental care, which involved mouth brooding and parental color change. Finally, we suggest that our results may be used to establish this species as a model for parental care and territoriality studies.

Apistogramma trifasciata（双鱼座：慈鲷科）双亲照顾的行为清单

慈鲷鱼表现出复杂的行为谱，主要是关于社会和繁殖行为。然而，尽管侏儒慈鲷表现出惊人的行为多样性，但对这些鱼进行的研究很少。Apistogramma trifasciata是新热带地区常见的侏儒慈鲷，广泛用作观赏鱼。雄性和雌性都是领土，并从事双亲照顾。在这里，我们观察到A的行为。三筋膜雄性和雌性以构建 ethogram。我们登记了一对夫妇从出生到后代独立的父母照顾。观察到了引人注目的行为，例如涉及绕圈展示和嘴角摔跤的男女比赛，以及涉及嘴巴育雏和父母颜色变化的父母照顾。最后，我们建议我们的结果可以用来建立这个物种作为父母照顾和领土研究的模型。
