Pterophyllum altum – AquaInfo
Introduction
Pterophyllum altum, also known as the Altum Angelfish or Orinoco Angel, is a species of freshwater fish that belongs to the cichlid family. Native to the Orinoco River basin in South America, these magnificent angelfish are highly sought after by aquarium enthusiasts for their striking appearance and peaceful nature.
Description
The Altum Angelfish is known for its tall and elongated body, which sets it apart from other angelfish species. It has a laterally compressed shape and can grow up to 20 centimeters in height. The dorsal and anal fins are long and flowing, giving the fish an elegant and graceful appearance. The body coloration can vary from silver to golden, with vertical black bars running along the body. These dark bars help the fish camouflage in its natural habitat.
In terms of behavior, Pterophyllum altum is a peaceful and social fish. They are best kept in groups of six or more to promote a sense of security and reduce stress. These angelfish are not aggressive towards other fish species and can be kept in a community tank with compatible tankmates. However, it is important to ensure that the tank is spacious enough to accommodate their tall body shape.
Habitat and Distribution
Pterophyllum altum is native to the Orinoco River basin in South America. They inhabit slow-moving rivers, flooded forests, and other freshwater habitats in the region. These angelfish are typically found in areas with dense vegetation and submerged tree roots, which provide them with shelter and protection.
Water Parameters
When keeping Altum Angelfish in captivity, it is crucial to replicate their natural habitat as closely as possible. The water temperature should be maintained between 26-30 degrees Celsius (78-86 degrees Fahrenheit), with a pH level of 6.0-7.5. It is recommended to use a high-quality filtration system to ensure optimal water quality.
Diet and Feeding
In the wild, Pterophyllum altum primarily feeds on small insects, crustaceans, and plant matter. In captivity, they should be offered a varied diet consisting of high-quality flake food, pellets, frozen or live foods such as brine shrimp, bloodworms, and daphnia. It is important to feed them small portions multiple times a day to prevent overfeeding and maintain their health.
Reproduction
The breeding behavior of Pterophyllum altum is fascinating to observe. During courtship, the male and female engage in a series of intricate displays, including fin flaring, body tilting, and mouth wrestling. Once a pair has formed, they will select a flat surface, such as a broad leaf or rock, to lay their eggs on. The parents take turns guarding and aerating the eggs until they hatch, which usually takes about 48-60 hours. The fry can be fed with newly hatched brine shrimp or commercially available fry food.
Conclusion
Pterophyllum altum, the Altum Angelfish, is a stunning fish species that adds elegance and beauty to any freshwater aquarium. With their peaceful nature and striking appearance, they are a favorite among aquarists. By providing them with the right habitat, water conditions, and diet, you can enjoy the company of these magnificent angelfish and create a thriving aquarium ecosystem.
