Guppies, Poecilia reticulata, have been extensively studied over the years and much is known about their mating habits and choices. Male guppies have varying color patterns that include many types of pigments.
Males prefer larger and more receptive females.
Whether males participate in mate-choice copying was unknown. To test this, focal males watched as model males courted females. Focal males were then allowed to choose between the same females. I found that not only did focal males not mate-choice copy, but they preferred the rejected females.
