This taller-bodied, tank-raised variant bears a strong resemblance to the true Altum Angelfish!
The Peruvian Altum Angelfish (Pterophyllum scalare "Peruvian Altum") is an uncommon variant of the classic angelfish. It has an extra tall body for its species and for a time was misidentified by some as the uncommon true Altum Angelfish (Pterophyllum altum), which is often wild-caught and much less durable than P. scalare. The extra tall body shape is not as pronounced in juveniles, but becomes much more obvious as this fish approaches 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 Peruvian Altum 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.
