Cichlid

Cichlids are fish from the order Perciformes. Cichlids are members of a group known as the Labroidei, along with the wrasses (Labridae), damselfishes (Pomacentridae), and surfperches (Embiotocidae). This family is both large and diverse. At least 1,650 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 2,000 and 3,000. Cichlids are among the most popular freshwater fish kept in the home aquarium. For more information, visit the Wikipedia entry Get back to Perciformes
