How Many Male Guppies Can Live Together – Color Pattern Variation in Male Guppies: Males with rare color patterns acquire more mates and have more offspring. Credit: Helen Rodd and Anne Houde
() —New research shows that the color pattern of a rare male guppy is more attractive to females and more offspring fathers.
How Many Male Guppies Can Live Together
“We think females may show this preference because it helps them avoid mating with close relatives,” said Helen Rodd of the Department of Ecology and Evolutionary Biology. “Guppies breed in small pools isolated from other pools in their stream and are often surrounded by fathers, uncles, brothers and cousins. By choosing a male that is sufficiently different from the others, the female can try to increase the chances of it. Not mating. with her.”

The researchers examined this mate preference behavior to explain the different colors and patterns in natural fish populations. The bodies and tails of male guppies in nature are covered with spots and stripes of various colors: orange, yellow, blue, purple, green, black and white. The size and locations of the spots vary from person to person. “We think this variation exists because when females prefer unusual looking males, these rare males leave behind many children and grandchildren, and slowly the color pattern of him and his descendants becomes more common. But when this color pattern becomes more common. common, those who have it leave fewer offspring, and therefore the metamorphosis of the color gradually decreases in prevalence. We expect the cycle of the metamorphosis of the color “.
Rod says the phenomenon is like the fashions of previous decades that are recycled over time. “For example, a small group of hipsters in Greenwich, New York City or San Francisco decide to dress like people from the 70s, and then a fashion designer looks at them and thinks, ‘Hey, that’s great’ and spreads the message. which here it is. It’s nice to dress this way. “Eventually many people dress the same and it’s no longer innovative and goes out of style, until a decade later another fashion-conscious person rediscovers the fashion of the years ’70 “.
“Except that the situation with these fish is similar, in this study we have shown that this deceptive behavior in female fish actually translates into male success with females and the ability to pass their genes on to the next generation. New ‘fads’. they appear as new color combinations. They arise and eventually we see many different species today. A visual balance is achieved with color patterns. It’s like living in a big city: we see a whole range of styles, including Gothic. “
Over time, the female guppy’s preference for males with unusual color patterns and the discovery of new color morphs and the recycling of old color morphs should have created the stunning range of colors we see in these fish, has explained Rod.
How Do Guppy Fish Reproduce?
The research team conducted its experiments in the natural habitat of guppies, small ponds in the streams of Trinidad. They captured all male and female guppies from four to six pools and divided them into two types: those with a lot of color on the caudal fin or those with very little color on the tail fin. In their experimental manipulation, they positioned males in pools so that in some pools, 75% of males had a lot of color on their tails and 25% of males had little color on their tails. They used the opposite ratio in other pools. He gave the girls little tattoos to mark which pool they came from and put them back in his own pool.
After 16 or 17 days, they collected the females, brought them to the laboratory, raised their offspring and found out which male was the father of each offspring. They repeated this experiment in three different streams, four to six pools each time. Females constantly prefer rare males.
