– The herbivorous cichlid fish Tropheus duboisi in Lake Tanganyika held feeding territories that were defended against individuals of the same but not the opposite sex. The male home ranges were 3 times as large as female home ranges, each overlapping with the ranges of 2–5 females. After spawning in the male's territory, each female foraged actively within her own territory while brooding the young in the buccal cavity. Both males and females rarely shifted their territories during the 6‐month observation period. The social organization of this fish was compared with that of a congener, Tropheus moorii.
