母性口育慈鲷通常被归类为两性二色性（例如，Baerends & Baerends-van Roon, 1950；Trewavas, 1983），雄性比雌性更亮。据信，这与这些物种的一夫多妻制交配制度有关，该制度对雄性施加选择性压力，为了吸引配偶而表现出明显的颜色。虽然对 Oreochromis mossambicus (Baerends & Baerends-van Roon, 1950; Neil, 1964; Lanzing & Bower, 1974) 和 0. niloticus (Falter, 1987, in press) 的雄性繁殖颜色模式进行了详细研究，但对雌性繁殖模式的观察并不完整。在求偶和产卵期间（例如，Turner，1986），最近对口育罗非鱼的全面综述（Trewavas，1983）将Oreochroniis描述为两色性竞技场产卵者。然而，根据本作者的独立观察（此处以我们的姓名首字母标识），我们得出结论，该声明需要进行限定。
Maternal mouthbrooding cichlids have generally been categorized as sexually dichromatic (eg, Baerends & Baerends-van Roon, 1950; Trewavas, 1983) with the males being brighter than the females. It is believed that this is related to the polygynous mating system of these species, which puts a selective pressure on the males to exhibit conspicuous colouration for the purpose of mate attraction. While male breeding colour patterns have been studied in detail for Oreochromis mossambicus (Baerends & Baerends-van Roon, 1950; Neil, 1964; Lanzing & Bower, 1974) and 0. niloticus (Falter, 1987, in press), observations on female reproductive patterns are less complete.Although some evidence shows that not all polygynous maternal mouthbrooders are sexually dichromatic during courtship and spawning (eg, Turner, 1986), the most recent comprehensive review of the mouthbrooding tilapiine fishes (Trewavas, 1983) characterizes Oreochroniis as sexually dichromatic arena spawners. However, following observations by the present authors independently (here identified by our initials) we conclude that this statement needs to be qualified.
