Cichlid
Cichlids ( /ˈsɪklɨd/) are fishes from the family Cichlidae in the order Perciformes. Cichlids are members of a group known as the Labroidei along with the wrasses (Labridae), damselfish (Pomacentridae), and surfperches (Embiotocidae). This family is both large and diverse. At least 1,300 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 1,300 and 3,000.
