Frequently Asked Questions
The most-asked questions about Narc angelfish.
What exactly is a Narc angelfish?
It is a recognized color morph of the freshwater angelfish (Pterophyllum scalare), distinguished in the hobby by its particular hue and fin patterning. Like all angelfish, it is a cichlid native to the Amazon River basin.
What species does the Narc belong to?
Every Narc angelfish is a Pterophyllum scalare, the same species behind silver, marble, koi, and zebra varieties. The 'Narc' label is a hobbyist designation for a specific color expression within that species.
How large do Narc angelfish typically grow?
Adults generally reach six to eight inches measured from the tip of the dorsal fin to the anal fin, with males often growing slightly larger. Providing a tall tank helps them display their full vertical fin spread.
What are the basic tank requirements?
A minimum of 55 gallons of water, a temperature around 78–82 °F (25–28 °C), and a slightly acidic to neutral pH (6.0–7.0) are the usual starting points. Smooth décor and gentle filtration are preferred because their long fins are easily damaged by sharp or rough surfaces.
What should I feed a Narc angelfish?
They are omnivores that do well on a mix of high-quality flakes or pellets supplemented with frozen or live foods like brine shrimp, bloodworms, and daphnia. Varying the diet helps maintain the vivid coloration the variety is known for.
Are Narc angelfish aggressive or territorial?
They can become noticeably territorial, especially a breeding pair guarding eggs or a large male defending a corner of the tank. Keeping them in a spacious setup with visual barriers and providing multiple hiding spots usually keeps interactions manageable.
Can I keep them with community fish?
Yes, provided the tankmates are of similar size and temperament and the tank is large enough to reduce competition. Small, fast swimmers like tetras or rasboras are common choices, while slow or long-finned fish are at higher risk of nipping.
How long can a well-cared-for Narc angelfish live?
With stable water parameters, a proper diet, and low stress, most individuals live five to ten years, and some exceed that. Consistent water changes and avoiding sudden parameter shifts are the biggest factors in longevity.
What is a notable behavior fans love to watch?
Narc angelfish are known for their graceful, slow gliding and the way they orient vertically to 'kiss' a mate or inspect the glass. Many keepers describe the long, flowing dorsal and anal fins swaying as the fish turns as one of the highlights of freshwater aquariums.
Where should a newcomer start learning about Narc angelfish?
Dedicated angelfish subreddits, hobbyist forums, and local fish-club meetups are good first stops for variety-specific tips. Pairing that with a few hours of reading on general cichlid care and water chemistry will cover most of what a new keeper needs before bringing one home.
