对坦噶尼喀湖中三种类似虾虎鱼的慈鲷的亲代照顾模式和交配系统进行了研究。在Tanganicodus irsaca中，雌性用嘴孵卵和幼崽大约两周，然后雄性接管这一角色大约一周。对标记鱼的现场观察表明，该物种是一夫一妻制的：雄性的活动范围与其配偶的活动范围大部分重叠，而它们的活动范围与体型相似的同性成鱼的活动范围是分开的。Eretmoduscyanostictus也进行雌性到雄性的口育育转变，并且似乎是一夫一妻制的。然而，第三个物种，Spathodus marlieri，只表现出母性的口育行为。讨论了这三个物种在亲本照顾和交配系统方面的差异与其摄食习性的关系，并将类似虾虎鱼的一夫一妻制模式与其他鱼类进行了比较。
Parental-care patterns and mating systems of three goby-like cichlids in Lake Tanganyika were investigated. InTanganicodus irsacaefemales mouthbrooded eggs and small young for about two weeks and then males took over the role for about one week. Field observations of tagged fish suggest that this species is monogamous: a male's home range largely overlapped with that of its mate, while their home ranges were segregated from those of similar-sized consexual adults.Eretmodus cyanostictusalso performed female-to-male shift of mouthbrooding and appeared to be monogamous. The third species,Spathodus marlieri, however, exhibited exclusively maternal mouthbrooding. The differences in parental care and mating system among the three species are discussed in relation to their feeding habits, and the pattern of monogamy in the goby-like cichlids is compared with those of other fishes.
