The reason we have recommended the use of non-Tanganyikan cichlid hosts above is because a successful captive spawning using Tanganyikan cichlid species has never been recorded! This may be due to an evolutionary process that has been observed in the lake, in which many cichlid species appear to have learned to avoid S. multipunctata when breeding. This is similar to the rejection of alien eggs by the host species in brood-parasatising birds. Because no species of brood parasatising catfish occu...

Bitterlings (see 'Notes') exhibit an unusual spawning symbiosis in which the interlamellar spaces of the paired inner and outer gills of living unionid mussels are used as a spawning substrate. During the reproductive period females develop a long ovipositor which is used to deposit eggs through the mussel’s exhalant siphon. Males then move in to males release milt...
