South America: Venezuela, Barbados, Trinidad, northern Brazil and the Guyanas. Widely introduced and established elsewhere, mainly for mosquito control, but had rare to non-existing effects on mosquitoes, and negative to perhaps neutral effects on native fishes (Ref. 12217). Africa: Feral populations reported from the coastal reaches of Natal rivers from Durban southwards, as well as in the Kuruman Eye and Lake Otjikoto in Namibia (Ref. 7248). Several countries report adverse ecological impact after introduction.
南美洲: 委內瑞拉,巴貝多,千里達,巴西北部與蓋亞那。 廣泛地在別的地方引入了而且建立了, 主要地對於控制蚊子, 但是在蚊子上對非現有的影響很少了, 而且在原生的魚上負面或可能沒有影響.(參考文獻 12217) 非洲: 野生的族群記錄自來自德爾班南方的納塔爾河的海岸範圍了, 以及在那米比亞的庫魯曼湖與湖 Otjikoto 中.(參考文獻 7248) 引入後的一些國家報告不利的生態衝擊。

生物学特性     字汇 (例如 epibenthic)

Inhabits warm springs and their effluents, weedy ditches and canals (Ref. 5723). Found in various habitats, ranging from highly turbid water in ponds, canals and ditches at low elevations to pristine mountain streams at high elevations (Ref. 11225). Occurs in wide variety of habitats with low predation pressure, usually in very small streams and densely vegetated lakes and springs (Ref. 59043). Has a wide salinity range but requires fairly warm temperatures (23-24 °C) and quiet vegetated water for survival (Ref. 7248, 44894, 79840). Feeds on zooplankton, small insects and detritus. One of the most popular aquarium fishes with many standardized varieties. Used in genetics research. Female reaches 5 cm SL (Ref. 2847). Males mature at 2 months and females at 3 months of age (Ref. 1672). Aquarium keeping: in groups of 5 or more individuals; minimum aquarium size 60 cm (Ref. 51539). A very popular and widely available species in the aquarium trade. In Australia, wild populations were established prior to the 1970s, undoubtedly the result of thoughtless aquarists discarding unwanted pets (Ref. 44894). Maximum length for female taken from Ref. 43281.

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | | 孕卵数 | 仔鱼

Males are about half the size of females with colorful tail and caudal fin; the anal fin is transformed into a gonopodium for internal fertilization. Males are continuously chasing and mating females. Females can store sperms for later fertilization and may produce young every four weeks. Pregnant females are recognizable by black triangle between anal and pelvic fins. After a gestation period of four to six weeks females give birth to 20-40 live young. No parental care is exercised and parents may even prey on their young.南美洲: 委內瑞拉,巴貝多,千里達,巴西北部與蓋亞那。 廣泛地在別的地方引入了而且建立了, 主要地對於控制蚊子, 但是在蚊子上對非現有的影響很少了, 而且在原生的魚上負面或可能沒有影響.(參考文獻 12217) 非洲: 野生的族群記錄自來自德爾班南方的納塔爾河的海岸範圍了, 以及在那米比亞的庫魯曼湖與湖 Otjikoto 中.(參考文獻 7248) 引入後的一些國家報告不利的生態衝擊。
