Black Neon Tetra – Detailed Product Description

• Overview & Appearance
  The Black Neon Tetra (Hyphessobrycon herbertaxelrodi) is a sleek and elegant freshwater fish known for its bold horizontal black stripe contrasted by a shimmering iridescent white or greenish line above it. This glowing line reflects beautifully under aquarium lighting, giving the fish a subtle yet captivating appearance. Its body is generally silver with translucent fins, making the dark stripe stand out even more. When kept in schools, their synchronized swimming creates a striking visual effect, especially in planted tanks.

• Tank Size & Setup
  Black Neon Tetras are schooling fish and should be kept in groups of at least 6–10 individuals. A minimum tank size of 10–15 gallons is suitable, though a 20-gallon tank or larger is recommended for a more natural display.
  Ideal tank setup includes:

  • A planted aquarium with live plants such as Java fern, Anubias, or Cryptocoryne

  • Dark substrate to enhance their coloration

  • Driftwood and natural décor for shelter

  • Moderate to dim lighting to highlight their iridescent stripe

A well-structured environment with both hiding spots and open swimming space helps them feel secure.

• Water Conditions
  Black Neon Tetras are hardy and adaptable but prefer stable conditions:

  • Temperature: 22°C – 28°C (72°F – 82°F)

  • pH Level: 5.5 – 7.5

  • Water Hardness: 2 – 15 dGH

  • Filtration: Gentle to moderate flow

  • Water Changes: Weekly 20–30% water changes recommended

They are more tolerant than many other tetras, making them beginner-friendly.

• Behavior & Temperament
  Black Neon Tetras are peaceful, calm, and social fish. They thrive in groups and display smooth, coordinated swimming in the mid-water level. They are non-aggressive and rarely nip fins, making them ideal for community aquariums. If kept in small groups, they may become shy and less active.

• Tank Mates
  Their gentle nature makes them compatible with a wide range of peaceful species:

  • Other small tetras (neon, glowlight, ember)

  • Rasboras

  • Corydoras catfish

  • Otocinclus

  • Dwarf gouramis

  • Small shrimp

Avoid aggressive or large fish that may stress or prey on them.

• Feeding Habits
  Black Neon Tetras are omnivores and easy to feed:

  • Staple Diet: High-quality flakes or micro pellets

  • Protein Foods: Brine shrimp, daphnia, bloodworms

  • Supplemental Foods: Occasional plant-based foods like spirulina

Feed 1–2 times daily in small portions. A varied diet helps enhance their coloration and health.

• Care & Maintenance
  These fish are low-maintenance and ideal for beginners:

  • Maintain stable water parameters

  • Provide a planted, low-stress environment

  • Avoid overfeeding

  • Perform regular tank maintenance

They are hardy but can still be affected by poor water quality if not maintained properly.

• Breeding Information
  Black Neon Tetras are egg scatterers and can be bred in captivity with the right conditions. A separate breeding tank with soft, slightly acidic water and dim lighting is recommended. Provide fine-leaved plants or spawning mops. Remove adults after spawning to prevent egg predation. Eggs hatch within 24–36 hours, and fry should be fed infusoria before transitioning to baby brine shrimp.
