For instance, the bluegill sunfish has three male genders, each of which reproduces in a different way. The largest, most aggressive males show off a flashy orange breast, and actively court females to lay eggs in their territory. In contrast, the smallest males are duller in colour and have no territory of their own, but will dart into one of the dominant male's territory's to fertilise some of his mate's eggs.

It is the medium-sized males who are the most surprising. They appear to actively court the larger males with a dance in the water. If the big male accepts their advances, they may then form a ménage a trois with an approaching female, with both males both fertilising her eggs.

Why would the larger male team up with the weaker partner in this way? One possibility is that his presence helps to reassure the female that the larger male is not too aggressive. For this reason, Roughgarden describes these medium-sized males as marriage brokers.
