Quelques espèces sont des prédateurs qui se nourrissent d'autres poissons et de leur progéniture. On ne trouve de plantes que dans quelques zones riveraines du lac. La plupart des régions sont faites de bancs de sable avec des pierres.

El lago Malawi de África ha desarrollado una fauna totalmente particular a lo largo de millones de años. Los cíclidos se han adaptado durante la evolución a los distintos hábitats del lago y formado especies endémicas (que únicamente viven allí). También dentro de las mismas especies han surgido variedades de color, ya que las distintas zonas rocosas están separadas a menudo entre sí por grandes superficies arenosas, por lo que constituyen una barrera natural para los peces. Por tanto, una especie en un lugar puede ser de color azul liso, mientras que en el siguiente conjunto rocoso a 1000 m de distancia es azul a rayas. Muchas especies de aguas poco profundas (hasta 15 m de profundidad) se alimentan de aufwuchs (algas con microorganismos) que van raspando de las rocas. Algunas especies son depredadoras que se alimentan de otros peces y sus crías. Solo se encuentran plantas en pocas zonas de los márgenes del lago. La mayoría de regiones se componen de superficies arenosas con rocas.

Il lago Malawi in Africa ha formato nel corso di milioni di anni una fauna unica, tutta sua. Nel corso dell’evoluzione i ciclidi si sono adattati ai differenti habitat del lago e hanno formato delle specie endemiche. Anche entro le specie stesse si sono formate delle varietà di diversi colori, essendo le scogliere separate tra di loro da grandi aree sabbiose e rappresentando così per i pesci una barriera naturale. Una specie che si trova in un certo punto può essere completamente azzurra e mille metri più avanti, sulla scogliera seguente, azzurra a righe. Molte specie da acqua bassa (fino a 15 m di profondità) si nutrono di Aufwuchs, raschiando dalle rocce le alghe e i microorganismi. Alcune specie sono predatori che si nutrono di altri pesci e della loro prole. Le piante si trovano solo in poche zone della riva. La maggior parte delle rive sono aree sabbiose disseminate di pietre.

The Lake Malawi in Africa has developed a quite unique fauna over millions of years. The cichlids have evolved to adapt to the lake’s diverse habitats and developed endemic (only existent there) species. Even within the species colour varieties have developed since rocky reefs are often separated by large areas of sand, which are a natural barrier for the fish. This way a species can be blue monochrome coloured at one spot and blue striped 1000 m away at the next rocky reef. Many species from the shallow water (up to 15 meters in depth) are grazing fish species which scrape the growth (algae with the microorganisms) from the rocks. Some species are predators which feed off other fish and their brood. Plants are only to be found at a few shore areas of the lake. Most of the regions consist of sandy areas with stones.

В озере Малави в Африке за миллионы лет возникла своя собственная фауна. Цихлиды адаптировались в ходе эволюции к различным местам обитания в озере и образовали эндемичные виды. Цветовые формы также развивались в пределах вида, так как скалистые утёсы часто разделены большими песчаными участками и представляют собой естественный барьер для рыб. Так один и тот же вид может быть в одном месте одноцветным синим, а в 1000 м дальше на следующем рифе - в синюю полоску. Многие виды с мелководных участков (глубиной до 15 м) соскабливают обрастания с камней (водоросли с микроорганизмами). Некоторые виды - хищные, которые питаются другими рыбами и их молодью. Растения растут только на прибрежных участках озера. Большинство регионов - песок и камни.
