Presentation
The guppy is a small freshwater fish native to South America, now one of the most popular aquarium fish species worldwide. It is characterized by vibrant colors and diverse patterns that vary greatly among individuals.
The guppy has a slender, laterally compressed body. Males display brilliant colors with highly developed tail and anal fins, while females are duller, gray or silvery, with less spectacular fins.
Characteristics
Indicative values: they vary by subspecies, sex and region.
Habitat and distribution
In the wild, the guppy inhabits freshwater rivers and lakes in tropical Caribbean regions, particularly in Trinidad and Tobago. It prefers calm, shallow waters rich in aquatic vegetation. In captivity, it adapts remarkably well to various aquatic environments.
CURRENT RANGE
The guppy is native to Trinidad and Tobago and northeastern Venezuela. However, due to repeated introductions through the aquarium trade, it has become established in tropical and subtropical regions worldwide, particularly in Africa, Asia, and Oceania.
Behaviour
The guppy is an active, sociable, and curious fish that naturally lives in groups. It spends most of its time exploring its environment and feeding. Males display elaborate courtship displays to attract females.
Reproduction
The guppy is viviparous, meaning females produce live young rather than laying eggs. They can produce multiple broods per year, each containing 10 to 50 fry. Reproduction is rapid, contributing to its success in the aquarium hobby.
Peculiarities
The guppy demonstrates remarkable genetic adaptation to extreme environments, including polluted waters. Females can store sperm from males and produce multiple broods without new mating. Its color patterns are highly variable and heritable, making it popular with breeders.
Threats and conservation
The guppy is not threatened in the wild and remains abundant in its natural habitats. However, its repeated introduction outside its native range poses ecological concerns, particularly for endemic local species.
Numbers and trends vary across sources and regions. See the IUCN assessment for the latest reference data.
