The Africаn greаt lаkes (including Tanganyika and Malawi) are famоus fоr their diversity оf cichlid fish species. These fish have radiated out into a whole complex of species - with diverse coloring and behaviors and specialized adaptation to different niches found in the lakes. They are a famous example of sympatric speciation. In their native lakes, these species rarely mate, but in an artificial setting (such as aquariums) different species are able to successfully reproduce together (but only when given no other choice). Behavioral factors and sexual selection may be important. Which reproductive barriers are most likely involved in their speciation in nature? Choose all that apply (multiple answer question)
