Altum Angelfish
Pterophyllum altum
Key differences: P. altum is significantly larger, reaching up to 18 cm (7 inches) in body length and over 30 cm (12 inches) in height. It has a more pronounced concavity above the snout, giving it a 'dished' face appearance, and its dorsal and anal fins are even more elongated and pointed. The vertical stripes on P. altum are typically darker and more defined, often extending into the fins. P. altum also has a higher ray count in its dorsal and anal fins and requires warmer, softer, and more acidic water conditions.
Leopold's Angelfish
Pterophyllum leopoldi
Key differences: P. leopoldi is the smallest of the Pterophyllum species, rarely exceeding 10 cm (4 inches) in body length. It has a straighter dorsal profile, less elongated fins, and a distinct dark spot at the base of the dorsal fin, often with a smaller spot above the eye. Its body is less disc-shaped and more elongated compared to P. scalare and P. altum.
