Altum Angelfish (Pterophyllum altum)
The Altum Angelfish, scientifically known as Pterophyllum altum, is a striking freshwater fish that hails from the Orinoco and Amazon River basins in South America. Revered for its majestic appearance and graceful swimming style, this species is a sought-after addition to aquariums, particularly for enthusiasts looking to showcase unique and beautiful fish.
Appearance
Altum Angelfish are distinguished by their tall, elongated bodies and long, flowing fins. They can grow up to 6 to 8 inches (15 to 20 cm) in length, with some individuals reaching even larger sizes. Their coloration is typically a stunning combination of silvery hues with vertical black stripes, and they often exhibit vibrant accents in shades of orange or yellow, especially in mature specimens. Their unique shape and striking colors make them a standout in any aquarium setting.
Habitat and Behavior
In the wild, Altum Angelfish inhabit the calm, acidic waters of flooded forests and slow-moving rivers. They prefer environments rich in vegetation and submerged structures, where they can find hiding spots and forage for food. These fish are social creatures and are often found in groups, displaying peaceful and curious behavior in their natural habitat.
Diet
Altum Angelfish are omnivorous and require a varied diet to thrive. In captivity, they should be fed high-quality flake food, pellets, and live or frozen foods such as brine shrimp, bloodworms, and daphnia. A balanced diet will not only promote their health but also enhance their vibrant colors.
Tank Requirements
To successfully keep Altum Angelfish, a spacious aquarium of at least 75 gallons is recommended, as they require ample swimming space. They thrive in slightly acidic to neutral water conditions, with a pH range of 6.0 to 7.5 and a temperature between 78°F and 84°F (26°C to 29°C). A well-planted tank with plenty of hiding spots, such as driftwood and rocks, will help mimic their natural environment and provide them with a sense of security.
Compatibility
Altum Angelfish are generally peaceful but can be territorial, especially during breeding. They can be housed with a variety of community fish, including larger tetras, rasboras, and other non-aggressive species. It’s best to avoid keeping them with small fish that may be seen as food or with overly aggressive tankmates.
Conclusion
The Altum Angelfish is a stunning and graceful addition to any freshwater aquarium, offering both beauty and intrigue. With proper care, a suitable environment, and a varied diet, these fish can thrive and flourish, captivating the attention of fish enthusiasts. Their majestic appearance and social nature make them a favorite choice among both novice and experienced aquarists, enriching the overall aquatic landscape.
