''Pterophyllum'' is a small genus of freshwater fish from the family Cichlidae known to most aquarists as "angelfish". All ''Pterophyllum'' species originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. The three species of ''Pterophyllum'' are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface. Naturally occurring angelfish are frequently striped longitudinally, colouration which provides additional camouflage. Angelfish are ambush predators and prey on small fish and macroinvertebrates. All ''Pterophyllum'' species form monogamous pairs. Eggs are generally laid on a submerged log or a flattened leaf. As is the case for other cichlids, brood care is highly developed. ==Species== The currently recognized species in this genus are: * ''Pterophyllum altum'' Pellegrin, 1903 * ''Pterophyllum leopoldi'' (J. P. Gosse, 1963) * ''Pterophyllum scalare'' (Schultze, 1823) (freshwater angelfish) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pterophyllum」の詳細全文を読む スポンサード リンク
