It occurs in temporary pools, swamps and ditches or rain pans, usually without connection to river courses (Ref. 30558). The adults die when waterbodies dry out with low rainfall (Ref. 30558). Males display to attract ripe females, pair off and spawn, grasping the female by folding over the large dorsal and anal fins (Ref. 30558). Spawning occurs daily for an extended period with a few eggs laid at a time (Ref. 30558). It is a bottom spawner (Ref. 27139, Ref. 30558) and development is suspended when the water bodies dry out (Ref. 30558). The eggs hatch the following rainy season when the pan fills, the fish growing to maturity in a few weeks (Ref. 30558). It are aggressive predators on insects and other aquatic invertebrates (Ref. 30558); therefore it is used for mosquito larva control (Ref. 30558). It is easy to maintain in the aquarium (Ref. 27139) and thus a popular aquarium fish (Ref. 30558).
它出現於暫時的水池，沼澤與溝渠中或者下雨窪地, 通常沒有和河段的關聯.(參考文獻 30558) 當 waterbodies 以低的降雨乾掉的時候，成魚死。 (參考文獻 30558) 雄性顯示吸引成熟的雌性, 成對分開而且產卵, 抓母魚被折疊的在大的背鰭與臀鰭之上.(參考文獻 30558) 每日產卵對於一個延長的時期具有一些卵放置一次.(參考文獻 30558) 它是一隻底部產卵魚 (參考文獻 27139, 參考文獻 30558) ，而且當水體乾掉的時候，發展被懸浮。 (參考文獻 30558) 當窪地裝滿的時候，卵孵化下列的雨季, 在幾個星期之內對成熟生長的魚.(參考文獻 30558) 它在昆蟲與其他的水生無脊椎動物上是侵略性掠食者;(參考文獻 30558) 因此它被用來蚊子幼體控制.(參考文獻 30558) 它是容易的在水族館 (參考文獻 27139) 維持與如此一個受歡迎的水族館魚.(參考文獻 30558)

Males display to attract ripe females, pair off and spawn, grasping the female by folding over the large dorsal and anal fins; spawning occurs daily for an extended period; few eggs are laid at a time; eggs are laid in the bottom sediments and development is suspended when the waterbodies dry out; eggs can endure dessication; eggs hatch the following rainy season when the pan fills, fish growing to maturity in a few weeks; males grow larger than females and are brightly colored; usually complete their life within a year (Ref. 30558).非洲: 在南方的索馬利亞的東方肯亞與下面的 Juba 河流域的低的 Tana 與 Sabaki 河流域.(參考文獻 27139) 在衣索比亞記錄來自 Wabi Shebele 流域了。 (參考文獻 58460)
