The guppy (Poecilia reticulata), also known as millionfish and rainbow fish, is one of the world’s most widely distributed tropical fish and one of the most popular freshwater aquarium fish species. It is a member of the family Poeciliidae and, like almost all American members of the family, is live-bearing. Guppies originate from northeast South America, but have been introduced to many habitats and are now found all over the world. They are highly adaptable and thrive in many different environmental and ecological conditions. Male guppies, which are smaller than females, have ornamental caudal and dorsal fins. Wild guppies generally feed on a variety of food sources, including benthic algae and aquatic insect larvae. Guppies are used as a model organism in the fields of ecology, evolution, and behavioural studies.
Guppies are native to Antigua and Barbuda, Barbados, Brazil, Guyana, Jamaica, the Netherlands Antilles, Trinidad and Tobago, the U.S. Virgin Islands, and Venezuela. However, guppies have been introduced to many different countries on every continent except Antarctica. Sometimes this has occurred accidentally, but most often as a means of mosquito control. The guppies were expected to eat the mosquito larvae and help slow the spread of malaria, but in many cases, these guppies have had a negative impact on native fish populations. Field studies reveal that guppies have colonized almost every freshwater body accessible to them in their natural ranges, especially in the streams located near the coastal fringes of mainland South America. Although not typically found there, guppies also have tolerance to brackish water and have colonized some brackish habitats. They tend to be more abundant in smaller streams and pools than in large, deep, or fast-flowing rivers. They also are capable of being acclimated to full saltwater as well as being used to cycle saltwater aquariums like their molly cousins.
Guppies are highly prolific livebearers. The gestation period of a guppy is typically 21–30 days, varying considerably. Reproduction typically continues through the year, and the female becomes ready for conception again quickly after parturition. Male guppies, like other members of the family Poeciliidae, possess a modified tubular anal fin called the gonopodium, located directly behind the ventral fin. The gonopodium has a channel-like structure through which bundles of spermatozoa, called spermatozeugmata, are transferred to females. In courted mating, where the female shows receptive behavior following the male’s courtship display, the male briefly inserts the gonopodium into the female’s genital pore for internal fertilization. However, in the case of sneaky mating where copulation is forced, the male approaches the female and thrusts the gonopodium at the female’s urogenital pore.
Once inseminated, female guppies can store sperm in their ovaries and gonoducts, which can continue to fertilize ova up to eight months. Because of the sperm-storage mechanism, males are capable of posthumous reproduction, meaning the female mate can give birth to the male’s offspring long after the male’s death, which contributes significantly to the reproductive dynamics of the wild guppy populations.
The guppy has been successfully hybridised with various species of molly (Poecilia latipinna or P. velifera), e.g., male guppy and female molly. However, the hybrids are always male and appear to be infertile. The guppy has also been hybridised with the Endler’s livebearer (Poecilia wingei) to produce fertile offspring, with the suggestion that, despite physical and behavioural differences, Endler’s may represent a subspecies of Poecilia reticulata rather than a distinct species.
