Study: Female Fish are Turned on by Male Gay Fish Sex
A study out of Germany found that a species of tropical male fish that are related to the guppy can attract female fish if it has sex with other males, the South African daily newspaper the Times Live reports.
German scientists from the University of Frankfurt claim that when small, non-dominant Atlantic molly males are passed up for larger and more colorful fish during mating season, they can increase their attractiveness by engaging in sex with other male fish.
Mollies are freshwater fish that come in a number of different colors and spot patterns, including black, white, black and white spots, orange and orange and white spots. The fish are also a relative of the guppy.
The researchers in the study questioned whether same-sex behavior in the Poecilla Mexicana would increase a male’s chances of mating with a female.
"P. mexicana females increase their preference for initially non-preferred males not only after observing those males interacting sexually with females, but also when having observed them initiating homosexual behavior," the scientists wrote of their findings in the journal Royal Society Biology Letters. They also wrote that female mollies usually prefer to mate with large, colorful and dominate males.
"As homosexual behavior is regularly seen in small P.mexicana males, we speculate that it might represent an alternative mating tactic used by subordinate, and thus, less attractive males," the researchers added.
