Ecologia
; acqua dolce benthopelagico; pH range: 7.0 - ? ; dH range: 12 - ?. Tropical; 22°C - 25°C (Ref. 2059); 5°S - 35°S
Africa: from the Orange River system and southern KwaZulu-Natal northwards throughout southern Africa, extending to southern Congo basin tributaries (Ref. 7248, 52193) and lagoons and rivers associated with Lake Malawi, but not the lake itself (Ref. 55954). Also in Lake Rukwa (Ref. 27292). Three subspecies are recognized: Pseudocrenilabrus philander dispersus, Pseudocrenilabrus philander luebberti and Pseudocrenilabrus philander philander.

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).
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
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.
