The Guppy is a tropical freshwater fish that has found success in aquaculture. Naturally occuring in northeast South America, they have been introduced across the world in an effort to control mosquito larvae. Female guppies will mate with multiple males, favouring the more colourful ones. She will birth up to 200 live fry (although usually 30-60). These tiny fish are indepedent from birth and the female is ready to breed again soon after. Popular in the pet trade, Guppies have been bred for flamboyance, with fancy tails and exaggerated fins.
