一些有领地意识的物种对不熟悉的同种物种的反应比已建立的邻居更有攻击性，这种行为被称为“亲爱的敌人”现象。研究人员进行了一项实验室实验，以确定一种名为Neolamprologus pulcher的非洲域鲷的雄性是否能够区分大小匹配的熟悉和不熟悉的雄性邻居，以及它们是否会对不熟悉的雄性做出更具攻击性的反应。研究发现，雄性在与不熟悉的邻居共享的领土边界附近花费的时间明显更多，并且对这些个体的攻击行为明显更多。
Some territorial species have been shown to react more aggressively toward unfamiliar conspecifics than established neighbors, a behavior referred to as the "dear enemy" phenomenon. Laboratory experiments were conducted to determine whether males of a territorial African cichlid, Neolamprologus pulcher, can discriminate between size-matched familiar and unfamiliar male neighbors and whether they respond more aggressively toward unfamiliar males. It was found that males spent significantly more time near the territorial boundary that they shared with unfamiliar neighbors and directed significantly more aggressive behavior toward these individuals.
