Beckford’s Pencilfish Red – Nannostomus beckfordi: A Comprehensive Care Guide
Introduction:
The Beckford’s Pencilfish Red (Nannostomus beckfordi) is a peaceful and colorful addition to freshwater aquariums. Known for its slender, elongated body and vibrant red tones, this species grows to about 1.5-2 inches (3.8-5 cm) in length, making it a perfect choice for nano tanks or community setups. Beckford’s Pencilfish is appreciated by aquarists for its calm behavior, unique body shape, and ability to thrive in planted tanks, creating a striking display in groups.
1. Natural Habitat and Behavior
Native to slow-moving streams and tributaries in South America, Beckford’s Pencilfish can be found in soft, acidic waters with dense vegetation. They are schooling fish, often seen swimming near the surface or middle of the water column. In the aquarium, these pencilfish display peaceful behavior and are best kept in groups of at least six to encourage natural schooling and minimize stress.
2. Aquarium Setup
A 20-gallon tank is suitable for a small school of Beckford’s Pencilfish, with soft, dim lighting that mimics their natural environment. Live plants, driftwood, and floating vegetation will make them feel secure and reduce stress. They prefer water parameters of pH 6.0-7.5, temperature between 73-80°F (23-27°C), and a gentle water flow. Fine, dark-colored substrate helps showcase their colors, while hiding spots and open swimming areas allow for comfortable, active behavior.
3. Diet and Feeding
Beckford’s Pencilfish are omnivores that primarily feed on small insects and invertebrates in the wild. In captivity, they thrive on a mix of high-quality micro-pellets, flakes, and frozen or live foods like brine shrimp, daphnia, and bloodworms. Feed them once or twice daily in small portions, offering a variety of food types to encourage their natural feeding behaviors and maintain optimal health.
4. Compatibility with Other Fish
As a peaceful community fish, Beckford’s Pencilfish can coexist well with other small, non-aggressive species. Ideal tankmates include tetras, rasboras, Corydoras catfish, and other peaceful fish. Avoid larger or aggressive tankmates that may intimidate them or view them as food. When kept in a school of six or more, they display the best behavior and remain less shy, as they gain confidence from being part of a group.
5. Common Challenges and Tips
- Water Quality: Beckford’s Pencilfish prefer soft, slightly acidic water. Ensure stable water parameters to prevent stress or illness.
- Diet Variety: To keep their colors vibrant and their health optimal, provide a balanced diet with live or frozen foods as a supplement.
- Tank Size: While they are small, they are active swimmers and enjoy space. Larger groups require a larger tank.
- Gentle Filtration: Pencilfish prefer gentle water flow, so adjust the filter to create a calm environment.
Conclusion
Beckford’s Pencilfish Red (Nannostomus beckfordi) is an elegant and peaceful species, ideal for aquarists seeking a colorful addition to a community tank. With the right environment and care, these fish can thrive and add a dynamic, natural feel to any planted aquarium setup.
