It is a very large family of fish made up of more than 2500 species. Cichlids come in many different sizes, from 2.5 centimeters to almost a meter long. All cichlids have some form of parental care for their eggs and fry. That parental care may come in the form of guarding the eggs and fry or it may come in the form of mouthbrooding. Cichlids are famous for their speciation in East African lakes.^[1][2]
