Diamond Head Neon Tetra:

A Comprehensive Care Guide

The Diamond Head Neon Tetra ($Paracheirodoninnesivar.$ “Diamond Head”) is a stunning and popular freshwater fish, a selectively bred variant of the classic Neon Tetra. Known for its brilliant metallic blue body and a distinct shimmering “diamond” patch on its head, this peaceful and active species is a captivating addition to any community aquarium.

Scientific Classification

• Scientific Name: $Paracheirodoninnesivar.$ “Diamond Head” (a selectively bred variety of the Neon Tetra)
• Family: Characidae
• Origin: Tank-bred (original Neon Tetra indigenous to the Amazon River Basin, South America)

Appearance and Size

Diamond Head Neon Tetras typically reach an adult size of 5 cm. They possess the iconic iridescent blue stripe running horizontally along their body, complemented by a bright red stripe beneath it. Their defining feature is the sparkling “diamond” shaped patch on their head, which gives them their name.

Temperament and Social Behavior

These fish are highly peaceful and are excellent for community tanks. Being schooling fish, they thrive and feel most secure when kept in groups of at least six or more individuals. A larger school will not only reduce stress but also showcase their natural schooling behaviors and vibrant colours more effectively.

Tank Requirements

• Tank Size: A minimum of 40 liters is recommended for a small group, but a larger tank 80 litres is preferable for better water stability and to accommodate a larger school.
• Substrate: A dark, soft, sandy, or fine gravel substrate is ideal. This helps to enhance their colours and mimics their natural habitat.
• Decorations: Provide a well-planted aquarium with plenty of hiding spots. Live plants such as Java fern, Amazon sword, and floating plants are highly beneficial. Driftwood and rocks can also be added to create a natural and secure environment.
• Lighting: Moderate lighting is suitable. Floating plants can help to diffuse the light and create shaded areas, which the Tetras appreciate.
• Filtration: A gentle filtration system is recommended, as strong currents can stress these small fish. A reliable filter will ensure clean and well-oxygenated water.
• Water Changes: Regular water changes of about 20% weekly are essential for maintaining excellent water quality and a healthy environment.

Water Parameters

Maintaining stable water parameters is crucial for the health and vibrancy of Diamond Head Neon Tetras.

• Temperature: 22∘C to 26∘C (72∘F to 79∘F)
• pH: Slightly acidic to neutral, with a range of 6.0 to 7.5. Some sources suggest a preference for slightly more acidic water (5.5 – 7.0).
• Hardness (GH): Soft to moderately hard water, generally 4-12 dGH (50 – 150 ppm).
• KH: 2-6 dKH (carbonate hardness)

Diet and Feeding

Diamond Head Neon Tetras are omnivorous and require a varied diet to thrive.

• Staple Diet: High-quality flake food or micro-pellets designed for tropical fish should form the basis of their diet.
• Supplements: Supplement their diet with live or frozen foods such as brine shrimp, daphnia, and bloodworms to provide essential protein and variety.
• Vegetable Matter: Including blanched vegetables (e.g., spinach, zucchini) or spirulina-based flakes can help ensure a balanced diet.
• Feeding Frequency: Feed small amounts once or twice a day, only what they can consume within one to two minutes.

Tankmates

Diamond Head Neon Tetras are peaceful and compatible with other non-aggressive community fish of similar size. Good tankmates include:

• Other small Tetras (e.g., Ember Tetras)
• Rasboras
• Guppies
• Corydoras catfish
• Dwarf Gouramis

Avoid keeping them with large or aggressive fish that may intimidate, stress, or prey on them. While generally safe with adult dwarf shrimp, they may prey on shrimp fry.

Breeding

Breeding Diamond Head Neon Tetras in a community tank can be challenging. If breeding is desired, a separate breeding tank with fine-leaved plants (like Java moss) and soft, slightly acidic water is recommended. They are egg scatterers.

Special Considerations

• Water Quality: Consistent monitoring and maintenance of water quality are paramount for their well-being.
• Shy Nature: These fish can be shy, especially in brightly lit tanks. Providing ample hiding spots will help them feel more secure and display their natural behaviors.
• Captive-Bred: As a selectively bred variant, Diamond Head Neon Tetras are readily available from reputable aquatic stores.

By providing these ideal conditions, the captivating Diamond Head Neon Tetra will flourish, bringing vibrant colour and active schooling behavior to your aquarium.
