Synodontis multipunctatus

Synodontis multipunctatus, also known as the cuckoo catfish, cuckoo squeaker, or multipunk, is a small catfish from Lake Tanganyika, one of the lakes in the Great Rift Valley system in Africa. It is a brood parasite upon mouthbrooding cichlids. This species grows to a length of 27.5 centimetres (10.8 in) TL. This species is a minor component of local commercial fisheries.[2]

General
Synodontis multipunctatus

Synodontis multipunctatus is one of a number of species of upside-down catfish in Lake Tanganyika, which is more famous for its cichlids. It gathers in large schools at depths of about 40 metres (130 ft) in the lake.

S. multipunctatus is notable for its breeding behaviour - it is a brood parasite, similar to the cuckoo from which it takes its common name. Lake Tanganyika is home to a number of mouthbrooding 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.

In the aquarium

Synodontis multipunctatus are a popular addition to cichlid aquariums. They grow to about 15 cm, and can be bred in captivity provided suitable hosts are present(?). Some aquarists have had success with host cichlids from Lake Malawi and Lake Victoria as well as those from Lake Tanganyika.[3] 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.

gollark: I think it's entirely possible that a generalized editor framework supporting injection into geometry dash and stuff would be *harder* than just making two editors.
gollark: Yes.
gollark: ffmpeg can apply filters and stuff.
gollark: Well, it would if all your usecases were exactly the same except some minor detail, but they aren't.
gollark: Just do all editing via ffmpeg.
