Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Assessed:	2006
Assessor/s:	Kasembe, J.
Reviewer/s:	Snoeks, J. (Freshwater Fish Red List Authority) & Darwall, W. (Freshwater Biodiversity Assessment Programme)
Justification: Endemic to Lake Malawi. Local decline reported in the southern arms of the lake, possibly due to the commercial trawl fishery, but the population is widespread throughout other parts of the lake where the fishery is absent.

Geographic Range [top]

Range Description:	Endemic to Lake Malawi with a lake-wide distribution.
Countries:	Native: Malawi; Mozambique; Tanzania, United Republic of

Population [top]

Population:	No information available.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	Found over mud/silt substrates normally in water deeper than 5 m but can penetrate to up to 100 m depth. Specimens caught at great depths are very large (with a maximum total length of 30 cm) occurring singly or in small groups. Feeds mainly on snails. It occurs in schools (a school may contain more than 100 fish) where there is only one male in breeding colouration. Each group has a large feeding territory. Spawning occurs at any site within the foraging territory of the school. This species may become territorial when more than one breeding male is present in a small area. Known by its scientific name in the aquarium trade.
Systems:	Freshwater
