Red Devil Koi Angelfish (Pterophyllum scalare)

The Red Devil Koi Angelfish is a stunning designer variant of the classic angelfish, combining the elegance of Pterophyllum scalare with intense, fiery red and orange koi-style patterning. Each fish is completely unique, with bold splashes of red, white, and black that resemble high-end koi—making every specimen a one-of-a-kind showpiece.

With their tall, triangular fins and graceful movement, these angelfish command attention in any aquarium. The “Red Devil” line is especially prized for its heavy red coverage and vibrant coloration, which continues to develop and intensify as the fish matures.

Originating from selectively bred Amazonian angelfish strains, this variety thrives in well-maintained freshwater aquariums with stable water conditions. They are semi-peaceful cichlids, best kept in carefully selected communities or species-focused setups.
