" Among the ancient Great Lakes of East Africa, Lake Tanganyika is the oldest and possesses about 250 species of cichlid fishes. Most are endemic species and have rapidly evolved with high diversification in morphology, behavior, and ecology through adaptive radiation into novel habitats. Cichlids are distributed from the shallow margins to the deep area in the lake, while the assemblages of the cichlid community indicate higher density and diversity in the shallow rocky regions in which some cichlid species that utilize similar diet niches coexist. In this chapter, I summarize research about feeding ecology, morphological traits in relation to foraging behavior and diet utilization, and food web structure in the cichlid community of Lake Tanganyika. Furthermore, I point out future directions in terms of current novel approaches that would contribute to understanding sympatric speciation with expanding novel diet/feeding niches, the diversification of species, food web constructions, and mechanisms for coexistance; including evo-devo, symbiosis with microorganisms in guts, stable isotope analysis, and behavioral syndrome/personality studies for the Lake Tanganyika cichlids. The integration of these studies will help us understand the ecological and evolutionary insights of feeding ecology and provide new aspects of adaptive radiation and sympatric speciation in Lake Tanganyika cichlids "
