The distribution of the percentage of the body of male guppies Poecilia reticulata covered with orange coloration influenced alternative mating tactics. At 15% mean coverage, male guppies interfered with other courting males more and engaged in courtship activities longer than males with 10% mean coverage. When males were tested in a situation with a wide variety of male types, males switched among females less frequently than when the variance among males was low.
