Guppy (Poecilia reticulata)

Care basics

Guppies are livebearers, which means females give birth to free swimming fry instead of laying eggs. Males have the long, colorful tails.

Keep two or three females for every male so no female gets chased constantly. Expect fry often. A planted tank gives babies places to hide.
