Map of Nicaragua showing the partial distribution of Midas cichlids in Nicaragua. Midas cichlids from the two great lakes (Managua and Nicaragua) colonized crater lakes Apoyo and Xiloá. In these two young crater lakes, multiple endemic species evolved in sympatry, representing a compelling case of parallel adaptive radiations. Within each crater lake, several deep-bodied, benthic and one elongated, limnetic species (A. sagittae in Xiloá and A. zaliosus in Apoyo) occur, which evolved rapidly within less than 2000 generations. White inset: Stable isotope analysis of carbon (δ13C) and nitrogen (δ15N) based on muscle tissue. δ13C and δ15N values vary significantly not only among environments, but also within each of the crater lakes where substantial variation can be observed among species. Within each of the crater lakes, variation in δ15N indicates differences in trophic ecology among species
