    Summary
    It is assumed that the sexes always face a conflict of interest over mating: each aims to benefit at the other's expense. In the cooperatively breeding cichlid fish, Neolamprologus pulcher, no such conflict is apparent: males benefit from mating with several females, but this incurs no detectable fitness costs to their mates.
