Native to the rivers, lakes, and streams of Central and South America, these cichlids vary greatly in size and temperament, making them suitable for a wide range of aquarium setups. Some of the most popular species include the Jack Dempsey, famous for its bold colours or the Geophagus that sift the sand with their mouths, changing your aquatic landscape every day. An interesting fact about these cichlids is their ability to adapt to a wide range of environmental conditions, which has contributed to their extensive diversification. For example, the Midas Cichlid can change its colouration based on mood and environmental factors, while the Convict Cichlid is known for its prolific breeding, even in captivity.
