[Ebook] The New Guide to Aquarium Fish – Ciclilids – GROUPS OF CICHLIDS – Medium/large South American Cichlids
In these regions cichlids are not the dominant predators and are rarely found in open water (where they would be easy prey for other fishes, birds, and reptiles) ; instead they occupy the margins of permanent bodies of water – lakes, rivers, and streams – where they can shelter among overhanging vegetation, roots, and fallen trees. Some are found beneath floating islands of plant debris. Most prefer still or slow-moving water, and do not appreciate bright lighting.
