Environment / Climate / Range
Freshwater; benthopelagic. Subtropical; 18°C - 24°C (Ref. 12468); 30°S - 34°S
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.5 cm TL male/unsexed; (Ref. 7248)
Africa: Cape coastal streams and rivers from the Keurbooms (south coast) to the Clanwilliam Olifants system (west coast), South Africa.
Occur mostly in coastal and lowland areas but may penetrate some distance inland; widespread in lakes and rivers (Ref. 3563). Prefer gentle currents within shelter of banks near the head of pools. Small but extremely hardy, they are known to tolerate a wide range of water and temperature conditions. Their small size and cryptic color enable them to avoid predators. Feed on small drifting invertebrates (Ref. 7248). Spawning period occurs in spring up to middle of summer (Ref. 33843).
