Diamond Head Neon Tetra

Diamond Head Neon Tetra

The Diamond Head Neon Tetra (*Paracheirodon innesi*) is a stunning freshwater fish known for its vibrant colours and unique diamond-shaped markings. This species is particularly cherished in the aquarium hobby for its shimmering body and peaceful disposition, making it a popular choice for community tanks.

Physical Characteristics:

• Size: Diamond Head Neon Tetras typically grow to about 3-5 cm (1.2-2 inches) in length.
• Coloration: They are characterised by their bright blue bodies with a prominent red stripe running horizontally along the length of their bodies. The 'diamond head' refers to their unique shape and patterning.
• Fins: Their fins are relatively small and delicate, contributing to their graceful swimming style.
• Shape: The body is laterally compressed, which is common among tetras, allowing for agile movement in the water.

Behavior:

• Temperament: Diamond Head Neon Tetras are generally peaceful and can coexist with a variety of tankmates. They thrive in schools and are more comfortable in larger groups.
• Activity Level: These fish are moderately active swimmers, often seen schooling together and exploring their surroundings. Their lively nature adds movement to the aquarium.
• Community Behavior: They can be housed in community tanks, but care should be taken to select peaceful tankmates. Providing plenty of swimming space and hiding spots will help reduce stress.

Aquarium Care:

• Tank Size: A minimum tank size of 40 liters (10 gallons) is recommended for a small group of Diamond Head Neon Tetras, although larger tanks are preferable for better water stability.
• Water Parameters:
  • Temperature: Diamond Head Neon Tetras thrive in warm water, with an ideal temperature range of 22°C to 26°C (72°F to 79°F).
  • pH: They prefer slightly acidic to neutral water, with a pH range of 6.0 to 7.5.
  • Hardness: Soft to moderately hard water, with a general hardness (GH) of 4-12 dGH, is ideal.
• Tank Setup:
  • Substrate and Decorations: A soft, sandy substrate is recommended. Diamond Head Neon Tetras appreciate a well-planted tank with plenty of hiding spots. Live plants like Java fern, Amazon sword, and floating plants provide cover and mimic their natural habitat.
  • Lighting: Moderate lighting is ideal for showcasing their colours. Floating plants can help diffuse the light and create shaded areas.
  • Filtration: A gentle filtration system is recommended, as strong currents can stress tetras. Regular water changes (about 20% weekly) are essential for maintaining a clean and healthy environment.

Diet:

Diamond Head Neon Tetras are omnivorous and require a varied diet to thrive. Their diet should include:

• Pellets: High-quality flakes or micro-pellets designed for tropical fish should form the staple of their diet.
• Live or Frozen Foods: Offer live or frozen foods such as brine shrimp, daphnia, and bloodworms to provide essential protein and variety.
• Vegetable Matter: Including blanched vegetables, such as spinach or zucchini, can help ensure a balanced diet.

Tankmates:

Diamond Head Neon Tetras can be housed with a variety of peaceful tankmates, including:

• Small Tetras: Such as Neon Tetras or Rummy Nose Tetras.
• Peaceful Rasboras: Like Harlequin Rasboras.
• Bottom-Dwellers: Corydoras catfish or other peaceful bottom-dwellers.

Avoid housing them with aggressive species or fin-nippers, as this can lead to stress or injury.

Breeding:

Breeding Diamond Head Neon Tetras can be rewarding and relatively straightforward under the right conditions:

• Breeding Setup: A separate breeding tank with shallow water (about 10-15 cm or 4-6 inches) is ideal. The water should be warm (around 24°C to 26°C or 75°F to 78°F) and slightly acidic (pH 6.0-6.5).
• Spawning Behaviour: The male will court the female and guide her to the spawning site. After spawning, the adults should be removed to prevent them from eating the eggs.
• Fry Care: Once the fry are free-swimming, they can be fed infusoria or newly hatched brine shrimp.

Special Considerations:

• Water Quality: Regular monitoring and maintenance of water quality are crucial for the health of Diamond Head Neon Tetras.
• Shy Nature: These fish can be shy, particularly in brightly lit tanks. Providing plenty of hiding spots can help them feel more secure.
