The blunthead cichlid, ''Tropheus moorii'', is a species of cichlid endemic to Lake Tanganyika in Africa. There are over 40 different color morphs of this species dispersed throughout the lake ranging from dark green to flame red and yellow. They mostly feed on filamentous algae on the rocky shallows that they inhabit.〔Takamura, Kenzi. "Interspecific Relationships of Aufwuchs-eating Fishes in Lake Tanganyika." Environmental Biology of Fishes 10.4 (1984): 225-41. Web. 22 Oct. 2013. .〕 ''T. moorii'' are maternal mouthbrooders so eggs are fertilized and carried in the mouth of the female while they hatch and develop.〔Steinwender, Bernd, Stephan Koblmüller, and Kristina M. Sefc. "Concordant Female Mate Preferences in the Cichlid Fish Tropheus Moorii." Hydrobiologia 682.1 (2011): n. pag. 31 May 2011. Web. 22 Oct. 2013. .〕 ==Territorialism== Both male and female adults occupy individual feeding territories.〔Yanagisawa, Yasunobu, and Mutsumi Nishida. "The Social and Mating System of the Maternal Mouthbrooder Tropheus Moorii (Cichlidae) in Lake Tanganyika." Japanese Journal of Ichthyology 38.3 (1991): n. pag. 28 June 2010. Web. 22 Oct. 2013. .〕 ''T. moorii'' inhabiting territories at greater depth tend to have smaller adult body sizes and larger territories.〔Kohda, Masanori. "Intra- and Interspecific Social Organization among Three Herbivorous Cichlid Fishes in Lake Tanganyika." Japanese Journal of Ichthyology 38.2 (1991): n. pag. 28 June 2010. Web. 22 Oct. 2013. .〕 Males have larger territories than females. A female will leave her territory to pair up with a male and usually visits several territories multiple times before choosing a male. After the male and female form a pair bond the female will forage in his territory for up to three weeks under his protection before spawning. A female's ovaries do not fully mature until she pairs up with a male and feeds from his territory. After spawning, the female will leave the male's territory to occupy a small unclaimed area for the mouthbrooding period. In contrast to the frequent movement of females, a male usually remains in his territory for months even if he is never visited by females.〔
