Found in various habitats, from flowing waters to lakes and isolated sinkholes, e.g., Lake Otjikoto, Namibia (see Ref. 27829); usually prefers vegetated zones. It feeds on insects, shrimps and even small fish (Ref. 52193). Breeds from early spring to late summer; males establish and defend a territory, construct a simple cleared nest and attract ripe females; eggs are laid in the nest, fertilized and collected by the female; the female withdraws to a quiet nursery area to brood the eggs, larvae and juveniles until they are able to fend for themselves (Ref. 7248, 52193). Ovophilic, agamous maternal mouthbrooder; no pair-bonding takes place (Ref. 52307).
從流動的水域到湖與孤立的陰溝入口處，例如，湖 Otjikoto ，發現於各種不同的棲息地了, 那米比亞;(見參考文獻 27829) 通常偏愛長滿植物的區域。 吃昆蟲，蝦甚至小魚。 從初春到夏末的繁殖; 雄性防護領土, 構造一個單一的被清除的巢而且吸引成熟的雌性。 卵在被受精而且收集母魚的巢中生產。 雌性撤回到一間育幼孵卵直到幼齡期。 (參考文獻 7248)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Female lays batches of eggs on a substratum which the male begins to inseminate. Female collects the eggs almost immediately after laying a batch and incubates eggs in her mouth for 12-14 days at 26°C, releasing the young after which. Parent guards the young for 5-7 days, keeping them into her mouth when approached by predators or divers. 非洲: 橘河系統，庫內內河，奧塔萬戈河，三比河流域，寬扎河， Cuango ， Cuilo ， Cassai ， Lufira, 盧阿拉巴河-Upemba ， Luapula-Moero ，馬拉威湖, 來自尚比西河下游的非洲東南部南至在納塔爾的 Vungu 河。
