The cichlid family is extremely large, comprising over 1000 species spread across Africa and the Americas. The members of this family are diverse in size, morphology and diet. Cichlids are some of the most celebrated freshwater aquarium fish in the hobby today. Important aquarium species include the Discus, Angelfish, Oscar, and the myriad African rift lake Cichlids. Of the latter group, those species from Lake Malawi and Lake Tanganyika in central Africa are the most popular. Cichlids are valued aquarium specimens because they are hardy, beautiful, and exhibit interesting behaviors. They are also commonly bred in aquariums. Some species, like the Oscar (Astronotus ocellatus) have a reputation for being intelligent and often form strong attachments to their keepers.
