Does a guppy lay eggs

The Guppy belongs to the Livebearer group and will give birth to free swimming fry instead of laying eggs. Guppies are easy to breed in aquariums and they will often spawn without any extra encouragement from their keeper. As soon as the fry are born, they will therefore be able to escape from their mother
Unlike most tropical fish, guppies give birth the live young, hence the guppy is classified as a mammal. :)
All types of guppies give birth to live young, hence they are classified as "livebearers".
