对非洲坦噶尼喀湖南端85 km湖岸线上沿着20个地点的48种常见丽鱼的地理颜色变异和分布进行了研究。16种有两种或两种以上的颜色变种，11种在研究区表现出有限的分布。他们都是岩石居民。分布边界主要分布在两个长桑迪上，长7和13 km。我们认为，长桑迪可以有效的障碍，对浅水岩栖慈鲷鱼的扩散。
Geographical colour variation and distribution of 48 common cichlid fish species were studied at 20 sites along an 85 km shoreline at the southern end of Lake Tanganyika, Africa. Sixteen species had two or more colour morphs and 11 species showed a limited distribution in the study area. They were all rock-dwellers. Distributional borders of the color morphs and species with a limited distribution mostly lay in two long sandy beaches, 7 and 13 km long. We suggest that the long sandy beaches can be effective barriers against dispersal of shallow-water rock-dwelling cichlid fishes.
