Size
Reaching a height of up to 15 inches from the tip of the dorsal to the tip of the anal fin, the Altum Angelfish is the largest of the angelfish species.
Diet
In their natural habitat, Altum Angelfish feed on small fish and invertebrates. In captivity, they require a varied diet of live, frozen, and prepared foods to maintain their health and coloration.
Sexing
Sexing Altum Angelfish can be difficult. Males may develop a nuchal hump, a common trait among cichlids, but this is often only visible during the breeding season.
Breeding
Breeding Altum Angelfish is challenging but rewarding. They require very soft, acidic water conditions for successful spawning. A dedicated breeding tank is recommended for those interested in raising fry.
Water Conditions
The Altum Angelfish thrives in warm water, with temperatures ranging from 82 to 90°F (28 to 32°C), a pH of 4.8-6.2, and extremely soft water hardness of 0-5°H. Learn how to create the perfect water conditions.
Ease of Care
Caring for Altum Angelfish can be demanding. They are sensitive to water quality and require a stable, well-maintained environment, making them best suited for the experienced aquarist.
Community Tank Compatibility
While peaceful, their size and dietary habits mean they should be kept with larger, similarly peaceful fish to prevent them from preying on smaller tank mates.
Species Variations
The Altum Angelfish is distinct from its relatives, with no recognized color variations. Its impressive size and finnage set it apart from other angelfish species.
Conclusion
The Altum Angelfish is a breathtaking species that offers a glimpse into the complexity and beauty of the Amazonian ecosystem. While not the easiest fish to keep, the rewards of maintaining this graceful giant are immense for those who are up to the challenge. With proper care, the Altum Angelfish can become the crowning jewel of any large, species-appropriate community aquarium.
