PTEROPHYLLUM ALTUM – MAJESTIC
Pterophyllum altum, commonly known as Altum, is a species of freshwater fish belonging to the family Cichlidae. It is native to the Orinoco River basin in South America, specifically in the countries of Colombia, Venezuela and Brazil.
Here is some comprehensive information about Pterophyllum altum:
Pterophyllum deep This graceful and beautiful fish has a laterally compressed body, a high dorsal fin, and long anal and pelvic fins. It has a deep body that ranges in color from silver to gold. A distinctive feature of this species is its long, triangular dorsal and anal fins, which extend vertically and can reach halfway up the fish's length. The dorsal and anal fins have a black stripe running along their base. The fish also has three vertical black stripes on its body.
Size:
Altumas are relatively larger compared to other angelfish species. They can grow up to 15–20 centimeters (6–8 inches) long and stand around 25–30 centimeters (10–12 inches) tall.
Behavior and temperament:
Pterophyllum altum is known for its shy and somewhat timid nature. They tend to be more sensitive and easily stressed than their closely related species, Pterophyllum scalare (common angelfish). Therefore, it is recommended to keep them in a peaceful and well-established aquarium with minimal disturbance. They are best kept in small groups or pairs, as they are social fish and feel more secure in the presence of their conspecifics.
Aquarium requirements:
To provide a suitable environment for Altums, the following aquarium requirements should be considered:
Tank size:
A spacious aquarium is essential for Altums. Ideally, a tank of at least 200 liters (50 gallons) or more is recommended to accommodate their size and swimming habits, and ideally, the tank should be at least 60cm high.
Water parameters:
Altumas prefer warm, acidic, and soft water, similar to their natural habitat. Ideal temperatures range from 25-29°C (77-84°F), a pH of 5,5-6,5, and a hardness of 1-5 dH. Aquarium-bred individuals are more tolerant and thrive in higher pH and hardness levels.
