Yes, guppies have been known to eat their own babies. This behavior is known as filial cannibalism and is common among many fish species. Guppies are livebearers, meaning that they give birth to live young rather than laying eggs. After giving birth, female guppies may eat their own offspring as a way to conserve energy and ensure the survival of their strongest offspring.
There are several reasons why guppies may eat their babies. One reason is that the mother may not have enough energy to care for all of her young. By consuming some of her offspring, she can conserve energy and provide better care for the remaining offspring. Another reason is that guppies may eat their weaker offspring as a way to ensure the survival of their strongest offspring. This is known as selective filial cannibalism and is a common behavior among many fish species.
While filial cannibalism may seem cruel, it is a natural behavior that has evolved over time to increase the chances of survival for the species. In the wild, guppies face many predators, and by consuming their weaker offspring, they can ensure that their strongest offspring have a better chance of survival.
However, in aquariums, filial cannibalism can be a problem for fish owners. If you want to prevent guppies from eating their babies, there are several things you can do. One is to provide plenty of hiding places for the young guppies to hide in. Another is to separate the mother guppy from her offspring once she gives birth. This can be done by placing her in a separate tank or using a breeding box.
In conclusion, while guppies do eat their babies, this behavior is a natural and necessary part of their survival strategy. By understanding this behavior, fish owners can take steps to prevent it and ensure the survival of their guppy offspring.
