(Characins) > Distichodontidae
Etymology: Distichodus: Greek, di = two + Greek, stix, stichos = line, row (Ref. 45335). More on author: Peters.
Environment / Climate / Range
Freshwater; pelagic. Tropical, preferred ?; 11°S - 21°S
Africa: middle and lower Zambezi (including Lake Kariba), Pungwe and Buzi rivers (Mozambique) (Ref. 52193). Reports of Distichodus mossambicus from the Congo basin are based on misidentifications (Ref. 96324).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 57.0 cm SL male/unsexed; (Ref. 52193); max. published weight: 7.6 kg (Ref. 52193)
Inhabits swift flowing water, rapids or quiet, deep, sandy or rocky pools (Ref. 13337). Found only in the mainstream of larger rivers and even in Lake Kariba prefers more riverine habitats; omnivorous, feeds on insects, snails, small fish, and aquatic plants; breeds in summer, moving upstream to suitable sites (Ref. 7248, 52193).
