 Because of the asymmetrical energy costs associated with internal fertilization, females in many Poeciliid species act as the choosy sex, with males exhibiting ornate coloration and morphology as well as elaborate courtship displays.However, "Limia" mostly lack display or extreme sexual dimorphism/dichromism.Of the known species, only the humpback limia ("L. nigrofasciata"), Perugia's limia ("L. Perugiae") and the blackbelly or Jamaican limia ("L. melanogaster") have been found to exhibit male courtship displays.
