One Fish, Two Fish, Red Fish, Blue Fish: How Variations in Color and Size Affect Frequency of Mating Behaviors in Guppies

Abstract

Abstract

When it was noticed that male guppies varied in colors in different parts of a stream, we wanted to know which variations were more attractive.  Using guppy models of various colors, we measured the mating behaviors of male guppies when presented with various options such as difference in color and difference in size (as opposed to the control).
