Cichlids are distributed in Central and South America, Texas (1 species), West Indies, Africa, Madagascar, Syria, Israel, Iran, Sri Lanka, and coastal southern India. Some species widely introduced. Body shape quite variable, mostly moderately deep and compressed. A nostril on each side of head. Interrupted lateral line in most species. Scales in lateral lines may be over 100, usually 20-50. Dorsal fin usually with 7-25 spines and 5-30 soft rays. Spines in anal fin 3-15 (generally 3); soft rays 4-15 (a few with 30). Subocular shelf absent. About 80 cm maximum length, in Boulengerochromis microlepis. Colorful cichlids are reared as aquarium fish. Breeding activities highly organized. Parental care in 3 forms: mouthbrooding, substratebrooding, and substratebrooding of eggs then mouthbrooding of young. Species flocks are reported from Africa. CLOFFSCA: The cichlids are the most species-rich non-Ostariophysan fish family in freshwaters world-wide, and one of the major vertebrate families, with at least 1300 species and with estimates approaching 1900 species (Kullander, 1998).
