cichlids, which care for their eggs and young by carrying them in their mouth. ''S. multipunctatus'' uses these, particularly '' Ctenochromis horei'' and '' Simochromis babaulti'', as unwitting caretakers for their children. The smell of spawning cichlids excites ''S. multipunctatus'' into spawning, and as the cichlids lay their eggs the catfish will quickly slip in and eat its eggs before they can be collected by the mother. While doing so they also release and fertilise their own eggs. The female cichlid will hastily attempt to scoop up her eggs and, in doing so, will also collect eggs from ''S. multipunctatus''. These eggs will then hatch inside the unwilling adoptive mother's mouth, and proceed to eat the cichlid eggs present before being released by the cichlid. This technique removes the burden of parental care from the ''S. multipunctatus'', and allows them to breed again sooner.

as well as those from Lake Tanganyika. They can be very aggressive and territorial towards other ''Synodontis'' species, they should be kept in groups over 3 to avoid competition between two, and proper cover and cave-like structures should be provided. They seem to be active in the day as much as the night and can prove quite lively. If kept in larger groups territorial issues are less likely.
