One of the favourite Tanganyikan cichlids among hobbyists, this species occurs in several geographical morphs. Each of these further exists in both blue and yellow-tailed forms. They congregate in large shoals of several thousand in nature, preying on zooplankton.
In the hobby you may also see C. leptosoma sp. “Jumbo” for sale. These fish grow to the size quoted above, whilst the “true” leptosoma only reaches around 4″ in length. Although it’s likely we are dealing with two different species (especially as different forms of sp. “Jumbo” also exist), for now all are classed as C. leptosoma and so are included together here. Care for all is virtually identical, although the smaller varieties such as C. leptosoma ‘Utinta’ should be kept with correspondingly smaller tankmates. None of these forms or morphs should be housed together in the confines of a tank as they can hybridise.
All are ideal Tanganyikan community fish, being peaceful, colourful and inhabiting a different area of the tank to most other species available. They also perform a useful function in acting as dither fish for more nervous tankmates.
