[[ Chromidotilapia nana ^ZBK ]]

Considering it´s relatively slender body and the low number of gill rakers on the lower limb of the first branchial arch, C. nana ^ZBK (9-10 rakers) is similar to C. mrac ^ZBK (8-9 rakers), but differs from the latter species in a poorly developed sexual dimorphism and dichromatism as well as in breeding behaviour (ovophilic in the former vs. larvophilic mouthbrooder in the latter). However, both exhibit a characteristic pattern of two rows of dark spots and blotches on the flanks, a feature which is not evident in other species within the genus.
