Adult male guppies use brightly colored patches to attract female mates. juvenile guppies are colorless. the original predator in the trinidad guppy experiment was the pike-cichlid, which feeds only on adult guppies. populations with no pike-cichlid predators had more brightly colored adults than populations that lived with the pike-cichlid. the killifish is another predator that feeds on guppies, but it only feeds on juveniles. a population of guppies is taken from a pond with pike-cichlids and placed in a pond with killifish. what will happen to the coloration in this population?

With each generation, it will be more common to have brightly colored males. This is because brightly colored males have more advantage with mating and having more offspring. Also, the predators don't attack/hunt adults. They are most likely to survive.
