Show Guppies are a FRESH WATER TROPICAL FISH. They only differ from regular guppies by being more colorful, beautiful, larger, more healthy and with more elaborate fin structures and cosmetic traits — due to the careful intervention of humans. No chemicals or other harmful elements are used in producing show guppies. (Poecilia reticulata), also known as the millionfish, is one of the most popular freshwater aquarium fish species in the world. It is a small member of the Poeciliidae family (females 46 centimeters (1.62.4 in) long, males 2.53.5 centimeters (1.01.4 in) long) and like all other members of the family, is live-bearing. Guppies are native to Antigua and Barbuda, Barbados, Brazil, East Timor, Guyana, Mayotte, Netherlands Antilles, Trinidad and Tobago, the US Virgin Islands, Venezuela, and Vietnam. However, guppies have been introduced to many different countries on all continents, except Antarctica. Sometimes this has occurred accidentally, but most often as a means of mosquito control, the hope being that the guppies would eat the mosquito larvae slowing down the spread of malaria.
