Peruvian Altum Angelfish

The Peruvian Altum Angelfish (Pterophyllum altum) is a distinctive and highly sought-after species of angelfish that originates from the Amazon River basin in South America. Unlike the more common Pterophyllum scalare, which are often referred to as "angelfish," the Peruvian Altum Angelfish belong to a separate species known for their tall, laterally compressed bodies and unique characteristics.

Here's some information about the Peruvian Altum Angelfish:

1. Appearance: Peruvian Altum Angelfish are known for their tall body shape, with a more vertical and compressed body compared to the horizontally flattened Pterophyllum scalare. They have elongated dorsal and anal fins, and their overall appearance is often described as elegant and regal.

2. Size: Peruvian Altum Angelfish are notably larger than Pterophyllum scalare. They can grow to be around 10 to 12 inches (25 to 30 cm) in height, including their fins. This larger size distinguishes them from the common angelfish.

3. Habitat: These angelfish originate from the Amazon River basin in South America, specifically the Orinoco and Rio Negro river systems. They are often found in areas with slower-moving waters, including floodplains and submerged forest areas.

4. Behavior: Peruvian Altum Angelfish are known for their skittish and sensitive nature. They can be more challenging to keep in captivity compared to the common angelfish (Pterophyllum scalare). Altum Angelfish are typically more sensitive to water quality, changes in environment, and handling.

5. Tank Requirements: Due to their specific habitat preferences and sensitivity, Peruvian Altum Angelfish require specific tank conditions. A larger tank with ample vertical swimming space is necessary to accommodate their tall body shape. They prefer soft, slightly acidic water conditions that mimic their natural environment. High-quality filtration and regular water changes are essential.

6. Diet: Peruvian Altum Angelfish are omnivorous, meaning they eat both plant matter and small aquatic organisms. Provide a balanced diet that includes high-quality pellets, flakes, live or frozen foods such as brine shrimp, bloodworms, and daphnia.

7. Compatibility: When selecting tankmates, choose peaceful fish that share similar water requirements. Avoid aggressive or fin-nipping species.

8. Acclimatization: These angelfish can be sensitive to changes, so proper acclimatization is crucial when introducing them to a new aquarium. Slowly adjust them to the tank water parameters over time.

Peruvian Altum Angelfish are revered for their unique appearance and behavior, making them a captivating option for experienced aquarium enthusiasts. Due to their specific care requirements and sensitivity, they are considered more challenging to keep than the common angelfish. If you're interested in keeping Peruvian Altum Angelfish, thorough research and dedication to proper care are essential for their well-being.
