Leopoldi Angelfish Large (Pterophyllum Leopoldi) Wild caught

Leopoldi Angelfish (Pterophyllum leopoldi) — also known as the Long Nose Angelfish — is the rarest and smallest of the three recognized angelfish species in the Pterophyllum genus. Wild-caught specimens from the Essequibo and Rupununi river systems in Guyana and parts of the Amazon basin are especially prized for their natural beauty and unique behavior.

Species Overview

• Scientific Name: Pterophyllum leopoldi
• Common Names: Leopold's Angelfish, Long Nose Angelfish, Roman-Nosed Angelfish
• Size: Typically 4–5 inches; can reach up to 6 inches in ideal conditions
• Lifespan: Up to 10 years
• Temperament: Peaceful but territorial during breeding
• Difficulty: Intermediate to advanced aquarists

Natural Habitat

• Found in slow-moving, soft, acidic waters of the Essequibo and Rupununi river drainage in Guyana and the Amazon basin.
• Prefers areas with broad-leaved vegetation, gentle currents, and plenty of hiding spots.
• Coexists with other South American cichlids in diverse ecosystems.

Aquarium Setup

• Tank Size: Minimum 30 gallons for a small group; taller tanks preferred due to long trailing fins.
• Water Parameters:
  • Temperature: 75–82°F (24–28°C)
  • pH: 6.0–7.5
  • Hardness: 3–12 dGH (soft to moderately hard)
  • Nitrates: Keep below 20 ppm
• Décor:
  • Broad-leaved plants, driftwood, and hiding spots
  • Gentle filtration and subdued lighting
• Tank Mates: Peaceful South American species like Corydoras, tetras, and other small cichlids

Diet

• Omnivorous: Feed a varied diet of:
  • High-quality pellets
  • Live/frozen foods: brine shrimp, bloodworms, daphnia, mosquito larvae
• Feeding Tip: Observe during feeding to ensure all fish get their share

Breeding

• Breeding Behavior:
  • Territorial during spawning
  • Subtle sexual dimorphism: males may have more pronounced anal fins
• Spawning Setup:
  • Provide vertical surfaces (e.g., broad leaves or slate)
  • Maintain stable water conditions and low stress
• Fry Care:
  • Eggs hatch in 2–3 days
  • Fry feed on yolk sacs initially, then baby brine shrimp
