Etymology: Serranochromis: Latin, serra = saw + Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; demersal. Subtropical; 23°S - 27°S
Africa: Sabie-Sand tributaries, Incomati River system, Transvaal; coastal pans between Incomati and Limpopo Rivers, Mozambique; Mgobezeleni Lake, Natal. Introduced to impoundments in the Kruger National Park (Ref. 7248). Threatened by depleted water supplies, sedimentation, pollution and invasive plants (Ref. 7248).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 37.0 cm TL male/unsexed; (Ref. 5693); max. published weight: 1.2 kg (Ref. 7248)
Prefers standing or slow-flowing pools with marginal vegetation (Ref. 7248, 52307), thrives in impounded waters (Ref. 7248). Preys on small fish, insects and other invertebrates, including snails (Ref. 7248, 52307). Male clears small nest and attracts female with quivering display (Ref. 7248). Eggs laid in several bouts (Ref. 7248) and fertilized before female collects them (Ref. 7248, 52307). Agamous maternal mouthbrooder (Ref. 52307). Batch spawner.
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Male clears small nest and attracts female with quivering display. Eggs are laid in several bouts and fertilized before being collected by the female (Ref. 7248). Female incubates the eggs in the mouth (Ref. 12251).
