The Philippine Blue Smokey Angelfish (Pterophyllum scalare), also known as the Philippine Blue or Cobalt Angelfish, is a very in-demand color variant of the classic angelfish. Juveniles often do not display the blue/turquoise coloration, but will develop it generously as they grow and approach maturity. This shoaling cichlid is relatively peaceful compared to other members of the cichlid family. It also has a very thin, tall body unlike most other cichlids. The Philippine Blue Smokey Angelfish is indigenous to several river systems in Northern South America, but virtually all specimens in the aquarium hobby have been tank-raised for generations.
