Purple Pencilfish (Nannostomus Rubrocaudatus) Aquarium Glaser

The Purple Pencilfish (Nannostomus rubrocaudatus) is a small and attractive freshwater fish native to the Amazon basin in South America. Here are some details about their care requirements:

1. Temperature: Purple Pencilfish prefer a tropical water temperature range between 73°F to 82°F (22.5°C to 28°C). Keeping the water temperature within this range will help ensure their well-being and promote their natural behaviors.

2. Minimum Tank Size: For a small group of Purple Pencilfish, a tank with a minimum capacity of 10 to 15 gallons is sufficient. It's important to remember that while they are small fish, they still need adequate space to swim and explore. A larger tank, such as a 20-gallon long tank, would provide more swimming space and allow for better water quality.

In terms of tank setup and care, here are some additional details:

• Tank Décor: Purple Pencilfish thrive in a well-planted aquarium. Provide plenty of live or artificial plants, driftwood, and hiding spots using rocks or caves. These fish are quite shy and appreciate areas to retreat to when they feel threatened or stressed.

• Water Parameters: Maintain good water quality with a pH level between 6.0 and 7.0 and soft to slightly acidic water. Use a good quality filtration system to keep the water clean, and regular water changes are essential to ensure optimal conditions.

• Lighting: Provide moderate to subdued lighting to mimic their natural habitat in dimly lit, shaded areas of Amazonian streams and creeks.

• Tank Mates: Purple Pencilfish are peaceful by nature but may become stressed if kept with aggressive or larger tank mates. They are often best suited for a community tank with similarly sized, peaceful fish. Small tetras, rasboras, and other peaceful species make good companions.

• Diet: These fish are omnivores and accept a variety of foods. Their diet can include high-quality flake food, small pellets, frozen or live foods such as daphnia, brine shrimp, and mosquito larvae. Variety in their diet is important for their overall health.

• Behavior: Purple Pencilfish are known for their interesting social behavior, often seen swimming in small schools or pairs. They are generally peaceful but can be a bit shy, so providing them with a well-planted tank and compatible tank mates will help them feel secure.

• Breeding: If you plan to breed Purple Pencilfish, provide them with ample vegetation for egg deposition. They are egg scatterers, and the fry can be raised on a diet of infusoria or very small live foods.

It's important to research and understand the specific needs of any fish species you plan to keep and to regularly monitor water quality to ensure the health and well-being of your aquarium inhabitants.
