科普一段坦湖圣经里关于藻垫的文字： The various cichlids living in the shallow Rocky habitat feed from the layer of algae and micro - organisms covering the rocks of their environment, so-called aufwuchs. In many places in this algal mat small invertebrates, such as crusraceans, mites, and insects and their larvae, find refuge and food, and these organisms are specifically preyed upon by some carnivorous cichlids, such as Neolamprologus and Julidochromis species.
