I love you and I'll eat it

This phenomenon occurs not only in the artificial living community, but also among wild fish. Filial cannibalism is when parents devour their offspring, either in the form of lice, larvae or eggs, just like the newborn or hatching.

With human thinking this is very rough, bizarre and unthinkable. The other is why it is strange that reproduction serves to maintain species. Then why do parents eat their offspring?

In the case of fish species, filial cannibalism is most common in fish species where the male is responsible for raising the offspring.

Scientists have made experiments to find out why the fish eat their juveniles. Where both parents take care of their offspring, there is pre-drinking egg consumption, but after they lay their own eggs, their activity is completely eliminated. It does not consume its own eggs or other eggs. It has also been observed that if the eggs are deposited from their parents for a longer period of time, the eggs will be destroyed.

Even if the twin box is small, they can eat the eggs, because the baby care would require more energy from the parents than the chance of growing offspring.

In the case of the offspring preparing for the female fish, it is more typical to devour the eggs because they have free access to the juveniles.
