Closely resembles L. capensis in coloration and in having well developed anterior barbels. Survives temperatures below 10°C. Found mainly in standing waters, shallow dams and muddy shallow areas such as in large impoundments. Juveniles feed on small invertebrates while adults feed on detritus and mud. Valued as an important, nutritious food source and is recommended for use in wastewater aquaculture in combination with other aquatic organisms (Ref. 6465).
