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 diet of Pterophyllum scalare consists of a wide spectrum of prey; they feed on tiny fish fry and younger, juvenile fishes, young and mature shrimps, crabs, prawns, various worms, mosquito larvae, and water bugs. Additionally, they will opportunistically catch any smaller-sized floating insects that have fallen onto the surface of the water.
Pterophyllum filicoides, a species named by Schlotheim in 1822, was established as the type species of Pterophyllum by Zeiller in 1906. [1] The name Pterophyllum was first introduced in 1825 by Brongniart, who described two species from the Upper Triassic found in Sweden. These species were P. minus and P. majus.
The most common species in hobbyist aquaria is Pterophyllum scalare from the Amazon River basin in tropical South America, known in the trade as the "angelfish". Other popular or readily available species include the oscar (Astronotus ocellatus), convict cichlid (Archocentrus nigrofasciatus) and discus fish (Symphysodon). [8]

Unlike P. scalare which prefer to spawn on the submerged leaves of plants and trees in the flooded rainforest, P. altum prefers to spawn on submerged roots and tree branches in a moderate water current. This species is recommended for intermediate to advanced aquarists due to the detailed maintenance it requires for proper health.
