Green Neon Tetra (Paracheirodon simulans) – Full Product Description

The Green Neon Tetra, also known as Paracheirodon simulans, is a stunning, peaceful freshwater fish native to the upper Orinoco and Negro River basins in South America. Often confused with the classic Neon Tetra, the Green Neon Tetra is slightly smaller and features a more vibrant green-blue iridescent stripe that runs across its slender body. Perfect for nano and community tanks, this species is prized for its dazzling color, ease of care, and schooling behavior that adds life and movement to planted aquascapes.

Key Features:

• Scientific Name: Paracheirodon simulans
• Common Name: Green Neon Tetra
• Adult Size: 1.5–2 cm (0.6–0.8 inches)
• Lifespan: 2–3 years
• Temperament: Peaceful and sociable
• Coloration: Bright iridescent green-blue stripe across a semi-transparent body
• Minimum Tank Size: 10 gallons

Water Conditions:

To maintain the health and coloration of your Green Neon Tetras, it's essential to replicate their natural blackwater habitat:

• Temperature: 22–28°C (72–82°F)
• pH Range: 5.0–7.0 (slightly acidic preferred)
• Hardness: Soft water (1–6 dGH)
• Water Flow: Low to moderate; avoid strong currents
• Tank Setup: Heavily planted with subdued lighting, dark substrate, and driftwood to simulate the natural Amazonian environment. Leaf litter and Indian almond leaves may be used to lower pH and create tannin-rich water, mimicking their native habitat.

Compatible Tank Mates:

Green Neon Tetras are peaceful community fish that do best in groups of six or more. When kept in larger schools, they feel secure and display their best coloration and natural schooling behavior.

Ideal tank mates include:

• Other small, peaceful tetras (e.g., Ember Tetras, Rummy Nose Tetras)
• Corydoras catfish
• Otocinclus
• Dwarf rasboras
• Peaceful dwarf shrimp (e.g., Amano or Cherry shrimp)
• Dwarf gouramis or Apistogramma (with caution)

Avoid housing them with larger, aggressive fish like cichlids or fin-nipping species that may stress or harm them.

Feeding Habits:

Green Neon Tetras are omnivores and accept a wide range of foods, making them easy to feed in captivity:

• Staple diet: High-quality micro pellets or tropical flakes
• Supplements: Live or frozen foods like baby brine shrimp, daphnia, and micro worms to enhance color and health
• Feeding frequency: 1–2 times daily in small amounts they can consume within 2 minutes

General Care:

• Perform weekly water changes of 25–30% to maintain pristine water quality
• Use a sponge filter or gentle filtration to prevent strong currents
• Maintain consistent water parameters; sudden changes can stress or kill tetras
• Acclimate slowly when introducing to new tanks, especially if soft, acidic water is used

Breeding:

While breeding in home aquariums is more challenging than with other tetras, it is possible under the right conditions:

• Separate breeding tank with very soft, acidic water (pH ~5.0)
• Temperature of 26–28°C (78–82°F)
• Spawning triggered by dim lighting and regular feeding of live foods
• Remove adults after spawning to prevent them from eating the eggs
• Fry should be fed infusoria or powdered fry food until they are large enough for baby brine shrimp
