Abstract Group living may engender conflict over food, reproduction, or other resources and individuals must be able to manage for social groups persist. Submission signals are an adaptation establishing maintaining hierarchy position, allowing a subordinate individual avoid protracted costly aggressive interactions with dominant individuals. In the daffodil cichlid fish (Neolamprologus pulcher), subordinates use submission resolve conflicts maintain their status within group. The complexity of physical environment affect value compared fleeing avoidance, which require certain features such as shelters effective. We investigated how ecological context affected expression in cichlids by examining behavior under different arrangements territories. altered number provided between each shelter condition scoring cooperative behaviors group members. found that members were modulated environment: displayed fewer more structurally complex environments dominants when present. Our results help elucidate role modulation group-living animals have implications welfare captively housed groups.
