Super Red Cenepa Pencilfish Care Guide

Introduction

The Super Red Cenepa Pencilfish, known scientifically as Nannostomus mortenthaleri, is a small, vibrant freshwater fish native to the Cenepa River in Peru. This species is highly sought after in the aquarium hobby for its striking red colouration and peaceful temperament, making it an ideal addition to a community tank.

Natural Habitat

In the wild, the Super Red Cenepa Pencilfish inhabits slow-moving streams and backwaters with dense vegetation and soft, acidic water. These environments provide abundant cover and feeding opportunities, creating the ideal conditions for these small and delicate fish.

Aquarium Setup

An aquarium for the Super Red Cenepa Pencilfish should include a soft, sandy substrate, plenty of live plants, and decorations such as driftwood and rocks to create hiding spots. A tank of at least 10 gallons is recommended, though larger tanks are preferable for maintaining stable water conditions. The use of floating plants can help replicate the shaded conditions of their natural habitat.

Water Parameters

Maintaining appropriate water conditions is crucial for the health of the Super Red Cenepa Pencilfish. The water temperature should be kept between 75°F and 82°F (24°C to 28°C), with a pH of 5.5 to 7.0 and soft to moderately hard water. Regular water changes of 10-20% weekly are necessary to keep the water clean and toxins-free.

Diet and Feeding

These pencilfish are omnivorous and prefer small live and frozen foods such as brine shrimp, daphnia, and bloodworms. Their diet should be supplemented with high-quality flake food or pellets. Feeding should occur twice daily, providing only as much food as they can consume in a few minutes to avoid overfeeding and water quality issues.

Behaviour and Social Structure

The Super Red Cenepa Pencilfish is a peaceful and social species that thrives in groups. Keeping them in schools of at least six will encourage natural schooling behaviour and reduce stress. Their peaceful nature makes them excellent companions for other small, non-aggressive fish.

Compatibility with Other Species

Due to their peaceful nature, these pencilfish can be housed with various other small, peaceful fish. Ideal tank mates include small tetras, rasboras, and other pencil fish. Avoid larger or aggressive species that might intimidate or eat these delicate fish.

Breeding

Breeding the Super Red Cenepa Pencilfish can be challenging but rewarding. They are egg scatterers, and successful breeding requires a separate breeding tank with plenty of fine-leaved plants or spawning mops. After spawning, the adults should be removed to prevent them from eating the eggs. The fry should be fed with infusoria or finely crushed flake food.

Health Considerations

Common health issues for pencilfish include bacterial infections, fungal diseases, and parasitic infestations. Maintaining clean water, a balanced diet, and a stress-free environment is crucial for preventing these health issues and ensuring the fish’s well-being.

Conclusion

The Super Red Cenepa Pencilfish is a beautiful and rewarding species to keep, offering a unique splash of colour and peaceful behaviour in a community aquarium. With proper care, suitable tank mates, and a well-maintained environment, these fish can thrive and provide much enjoyment to their keepers.
