Guppies are small fish that are native to South America and the Caribbean Islands. They come in a variety of colors and sizes, but the smallest type of guppy is considered to be the Endler’s Livebearer, which can reach an adult size of just one inch in length. In comparison to other types of guppies, they have shorter bodies with more colorful markings on their faces and fins. These tiny fish live for up to four years on average and feed predominantly on algae-based foods such as flakes or pellets. The males tend to have brighter coloration than females, although both sexes have similar life spans. The Endler’s Livebearer makes a great addition to any freshwater tank due its peaceful nature and low maintenance requirements. This species is also quite hardy so it can adapt well even when water quality isn't ideal for most other tropical fish species.
