Guppies mature within 10-20 weeks and can live up to 4 years, in that time females can have many broods of fry. Lifespan in the wild differs from that of a live tank, but depending on the dynamics of the aquarium guppies can live slightly longer than in the wild.

With a well planned out aquarium that has plenty of rocks and vegetation, guppies can be a great addition. Be careful of predator fish within the tank, however, and make sure the guppies have plenty of hiding spots for themselves and their fry. Guppies have also been known for infanticide, so make sure your guppies are well fed and not crowded, as these are common reasons for them to do it. With the proper knowledge and care, guppies make a great addition to any tank.
