The guppies have strong survival ability and strong genes. They can inbreed, so guppies in the same brood can mate and reproduce. But even the best genes. Too much inbreeding can also lead to degeneration problems in their offspring. If the offspring are mated within three generations, the degeneration will not be too serious. The offspring can also grow and develop normally and continue to reproduce.
However, if more than the third generation, then inbreeding. The fish they produce are prone to disease or do not develop properly. In severe cases, stillbirth will occur. Therefore, the guppies bred in the same nest can be controlled within three generations at most.
Guppies have many strains, including hybrid varieties. They have a strong reproductive capacity, even if the species is different, they can also reproduce and mate. By stringing seeds, their shape and body color can be changed. Different species of guppies are mixed together, and their offspring are different. The pattern and color of the small fish are different from those of the parent fish, and almost every one looks different. However, only in the case of human intervention, they will cross species mating.
