摘要: A species of the cichlid genus Pelmatochromis recently imported from West Africa has been observed in captivity and was bred several times. Whereas females all looked alike males differed respect two colour patterns: 1 the number eye spots tail fin is constant throughout individual's life but varies between 0 5 among different individuals; 1 some always become red on whole underside belly when courting (type 1) others hind part only 2). There strong evidence that these differences coloration are genetically determined.
