Differenze di genere

The sexes are easy to distinguish based on their appearance: males are slightly smaller and more distinctive in color. Depending on the breed, their caudal fin is also much larger than that of the female animals. In the case of cultivars or the wild form as well, it is sometimes not that obvious. Here it is advisable to look at the anal fin. The anal fin of the females is triangular, while that of the males is elongated. The male’s anal fin is also known as the gonopodium. It is the copulation organ.

Riproduzione

Guppies are viviparous; a litter consists of around 20 young animals. After mating, the females are able to store the semen for some time. This means that several pregnancies can result from just one mating. This fish species do not take care of the brood. Adult animals even eat their own offspring. If you want to breed, you should separate the young guppies from their parents right after they are born. You can socialize them again later. If the offspring no longer fit into the mouth of the adult guppies, you no longer have to fear losses.

Dimensione del gruppo

The sociable guppies should always be kept in a group. With some guppy keepers, pure male keeping is popular because it is sure to keep offspring. It is common and very practicable to keep many females with a few males in a group. This gender ratio is justified by the fact that the individual female in this constellation is less exposed to the obtrusive advertising behavior of the males. However, behavioral researchers found that guppy advertising and mating behavior can be influenced by gender ratio. It may even be more beneficial to keep more males than females, for example, 6 males and 3 females. However, there shouldn’t be too many males per female: The study results suggest that this again leads to a stressful situation for the females. It is of course important to prevent this!
