There can be some confusion about the term “angelfish” since the saltwater aquarium hobby has marine angelfish, so we are specifically referring to the angelfish cichlids of the Pterophyllum genus that have long, wing-like fins and come from freshwater rivers in South America. The three known species of angelfish include P. altum (the largest species), P. leopoldi (the rarest species to find in fish stores), and P. scalare (the most available species found in pet stores).
What are the different angelfish types and colors? New colors and patterns of angelfish are constantly being developed, but some of the most well-known varieties include silver (or wild type), veil, koi, zebra, marble, albino, leopard, and platinum.
How big do angelfish get? These fish get to the size of a small saucer, so be prepared to give them plenty of space. The common P. scalare angelfish has a body length of up to 6 inches (15 cm) and a height (including their fins) of 8 inches (20 cm). Altum angelfish (P. altum) can grow up to 7 inches (18 cm) long and 10-13 inches (25-33 cm) high.
