Genetic data collected on co-operatively breeding Neolamprologus pulcher groups from Lake Tanganyika revealed mixed parentage in 80% of the groups examined. A case (1/11) of shared maternity was detected where a subordinate female bred alongside the dominant female in a social group. Extra-pair paternity was assigned to other dominant males who held their own social groups, but subordinate males were not found to father young in any group (0/9).
从坦噶尼喀湖合作繁殖的 Neolamprologus pulcher 群体中收集的遗传数据显示，80%的被检查群体存在混合血统。在一个社会群体中，一只从属雌鱼与一只优势雌鱼一起繁殖，检测到了一个共享母性的案例（1/11）。额外的父权被分配给其他拥有自己社会群体的优势雄鱼，但没有发现从属雄鱼在任何群体中生育后代（0/9）。
