Quick Overview of the Red Devil Angelfish
The Red Devil Angelfish (Pterophyllum scalare var. “Red Devil”) is one of the most sought-after and vibrant selectively bred color strains in the cichlid family. Reaching a majestic adult size of 6 inches (15 cm) in body length and over 8 inches (20 cm) in total height, this centerpiece fish stands out for its deep, fiery red-orange body pigmentation. Enhanced by dark marbled patches and shimmering iridescence along its fins, the Red Devil strain loses little of its intensity as it matures compared to lower-grade koi variants. Highly social and curious, they readily recognize their owners and glide gracefully across the middle and upper layers of the aquarium.

Local Care Tips for Bacolod Aquarists
Bacolod Tap Water Match & Filtration Needs: Red Devil Angelfish adapt smoothly to Bacolod’s typical neutral-to-slightly-hard tap water (pH 6.8–7.5) when properly conditioned with a high-grade dechlorinator during water changes. Because they prefer clean water with low nitrates, maintain a regular weekly water change schedule. Adding natural driftwood or local Talisay (Indian Almond) leaves releases beneficial humic acids that support slime coat health and enhance their fiery orange pigmentation.
Aquascaping Strategy & Epiphyte Care: Their tall, compressed bodies are designed to navigate around tall plants like Vallisneria and broad-leaved Amazon Swords. They are 100% safe with aquatic vegetation and look spectacular swimming among driftwood roots. Frame your hardscape with easy epiphytes like Anubias Barteri, Java Ferns, or Bucephalandra attached securely to rocks or wood—just ensure the creeping rhizomes of these epiphytes remain completely exposed above the substrate to keep them from rotting!
Dietary Needs & Tankmate Compatibility: To maintain their intense red-orange coloration, offer a varied diet rich in natural carotenoids, such as color-enhancing cichlid flakes, micro-pellets, and regular treats of frozen bloodworms, brine shrimp, and krill. Red Devil Angelfish make outstanding community centerpiece fish alongside Rummynose Tetras, Congo Tetras, Corydoras, Plecos, and Gouramis. Use caution with tiny micro-fish (like Chili Rasboras) or dwarf Neocaridina/Caridina shrimplets, as full-grown angelfish may view them as natural live snacks. A secure glass canopy or lid is recommended to prevent accidental leaps if startled.
