Introduction Cooperative breeding describes a natural phenomenon where supernumerary sexually mature individuals (hereinafter called helpers) temporarily forgo their own reproductive opportunities and assist in raising the conspecific offspring of others, thus resulting in more than two

investigate how group members of a cooperatively breeding cichlid fish respond to simulated visitors, and whether a group member’s social status influenced their response to these visitors. There are multiple ways in which visitors could inflict costs and these costs are likely to differ across individual
described as despotic, with weak tolerance levels among group members and well-differentiated relationships organised in a strong linear hierarchy (Archie et al., 2006 ; Bergstrom & Fedigan, 2013 ). This type of hierarchy has been described in cooperatively breeding invertebrate societies (Cronin & Field

constraints (Matsumura & Hayden, 2006; Wong, 2010; Reddon et al., 2022), and therefore social stability relies on effective communication (Frommen, 2020). The daffodil cichlid ( Neolamprologus pulcher ) is a cooperatively breeding freshwater fish endemic to Lake Tanganyika, East Africa (Taborsky & Limberger
