Which group includes aquarium species such as guppies and swordtails?

Explanation:
Livebearing describes fish that give birth to live young instead of laying eggs. Guppies and swordtails are classic examples of livebearers in the aquarium world; fertilization is internal and the female gives birth to small, free-swimming fry rather than laying eggs. This differs from bubble-nest builders, which rely on surface nests to protect eggs, and from egg-layers and egg-scatterers, which lay eggs that hatch outside the body. So, the group that includes aquarium species such as guppies and swordtails is livebearers.
