 Less important as predators of juvenile "L. capensis" are largemouth bass ("M. salmoides"), spotted bass ("M. punctalatus") and bluegills ("Lepomis macrochirus").Largemouth bass, bluegills and banded tilapia are also food competitors of young Clanwiliam yellowfish.Habitat destruction by canalisation and damming as well as water pollution by pesticides and fertilisers in the runoff of agricultural land are affitional threats.
