What do guppies look like when mating

Male guppies will bend their spine to the side and will start flaring, dancing, and jiggling around female guppies. I can ensure you, that there is nothing wrong with your fish. This is the mating behavior of guppies. Males will do this mating ritual all day long. Nov 22, 2021 (source)
It is easy to determine when a female is pregnant by her body shape. The female will get much larger and develop a gravid spot on her abdomen, which becomes darker and darker as birth nears. After birth, she will be ready to produce another brood in one month’s time. (source)

In guppy courtship, the male guppy performs a type of dance around the female to express his interest. If the female wants to participate in this courtship ritual, she will respond to the approach and move toward the male. May 15, 2019 (source)
Signs that your goldfish are ready to mate include white spots along the gills of the males, and the female will become fatter and more rounded. The male will then chase the female around the tank to encourage her to release her eggs. Jun 26, 2018 (source)
Chasing. While some levels of guppy chasing are normal (especially when a male chases a female), constant chasing definitely isn’t. If a male is constantly chasing other males, or if a female is constantly being harassed, then it may be bullying and fighting occurring, rather than mating behavior. (source)
Many pregnant female guppies start to exhibit behavioral changes, too. Females tend to get pretty aggressive when they’re pregnant. While they can exhibit some feisty behavior towards any fish that gets in her way, pregnant females tend to direct most of their anger at the males. Jun 11, 2021 (source)

One of the most common signs of aggression is when one guppy is constantly chasing another. This is because they’re trying to assert their dominance by scaring them and attacking them. While it occurs more in males, it doesn’t mean females won’t do it either (you’ll find out more about this later). (source)

“If the female is receptive, she glides over to the male.” But, if females don’t show interest, males continue to pursue them. They sneak around the female from behind or below, and try to force sperm into her without her cooperation. This behavior is common in guppies in the wild, Kwan said. Jul 23, 2013 (source)
We confirmed that females in the multiple group had successfully copulated with more than one male by observing their behavior during mating trials and by using a highly polymorphic microsatellite marker to determine paternity in multiply sired broods. (source)
