Green Glo Tetra

Scientific Name

Gymnocorymbus ternetzi (genetically modified)

Physical Appearance

• Size: Grows up to 2.5 inches (6–6.5 cm).
• Coloration: Neon green glow under normal light; fluoresces more vividly under blue or blacklight.
• Body Shape: Oval and slightly compressed laterally, typical of the Black Skirt Tetra.

Temperament and Behavior

• Nature: Peaceful and social.
• Schooling Fish: Best kept in groups of 6 or more for comfort and natural behavior.
• Tank Level: Active swimmers that occupy the middle of the tank.

Tank Requirements

• Tank Size: Minimum of 15 gallons for a small group.
• Water Parameters:
  • Temperature: 72–82°F (22–28°C)
  • pH: 6.5–7.5
  • Hardness: 5–15 dGH
• Substrate: Sand or fine gravel.
• Decoration: Plants, driftwood, and hiding spots to mimic a natural habitat. Open swimming areas are essential.

Diet

• Type: Omnivorous.
• Food: High-quality flakes, pellets, freeze-dried, or frozen foods like bloodworms and brine shrimp. Vegetables (blanched spinach or zucchini) can also be offered occasionally.

Compatibility

• Good Tank Mates:
  • Other GloFish species
  • Small peaceful fish (e.g., neon tetras, rasboras, guppies)
  • Corydoras catfish, snails, and shrimp.
• Avoid: Aggressive or large predatory fish.

Care Level

• Difficulty: Easy, suitable for beginners.
• Maintenance: Regular water changes (25% weekly) and stable water parameters are critical. Avoid strong currents.

Breeding

• Difficulty: Moderate to difficult in home aquariums.
• Reproduction: Similar to Black Skirt Tetras. They are egg scatterers, and parents do not care for the eggs or fry.
• Setup: Use a separate breeding tank with fine-leaved plants or a spawning mop. Remove adults after spawning to prevent egg consumption.

Interesting Facts

1. Non-Toxic Modification: Their glowing color comes from harmless genetic modification, and they are bred in captivity, not taken from the wild.
2. Eco-Friendly Alternative: GloFish are marketed as a sustainable option for those who want colorful fish without impacting natural populations.
3. Regulations: Some countries restrict or prohibit the sale of genetically modified organisms, including GloFish, so availability may vary.
