As well as the fish that survive in aquarium shops, in 1997 staff from the Taipei County fish breeding station discovered six individual paradise fish at locations in the Sanchih and Kungliao areas of Taipei County, and in Miaoli County. They were delighted, and in view of a growing epidemic of dengue fever at the time, embarked on a program for the large-scale breeding of these "mosquito hunters."
除了在水族館留下倩影，民國八十六年，台北縣農業局水產種苗場人員在三芝、貢寮、苗栗陸續發現零星落單的六隻鬥魚，養殖場見獵心喜，尤其當時登革熱疫情滋長難扼，「捕蚊魚」的大規模人工繁殖於焉展開。
