GloFish Tetra: The Bright and Lively Glow in Your Aquarium

If you want to bring some dazzling neon colors and lively activity into your freshwater community tank, GloFish Tetras are an eye-catching and fun choice. These genetically enhanced fish feature glowing fluorescent colors that pop beautifully under LED and blacklight aquarium lighting, creating an exciting and futuristic underwater display.

What is a GloFish Tetra?

GloFish Tetras are a genetically modified version of the popular Black Skirt Tetra (Gymnocorymbus ternetzi). They come in vibrant fluorescent colors such as bright red, green, blue, and orange. This vivid coloration is visible even under normal aquarium lighting but truly shines under blue or blacklight, making them a favorite for aquarists who love bold colors.

Why Choose GloFish Tetras?

  • Bright Neon Colors: Their glowing fluorescent hues create a spectacular visual effect, especially in dim or blacklight conditions.

  • Peaceful and Social: Like other tetras, they’re schooling fish and thrive in groups of 6 or more.

  • Hardy and Easy to Care For: Great for beginners and experienced aquarists alike.

  • Active Swimmers: Add constant movement and life to the mid-level of your aquarium.

Tank Setup and Care

  • Tank Size: Minimum 20 gallons to comfortably house a small school of 6 or more.

  • Water Temperature: 70–82°F (21–28°C).

  • pH Level: 6.0–7.5, neutral to slightly acidic water preferred.

  • Lighting: Regular aquarium lighting is sufficient, but blue or blacklight brings out their fluorescent colors best.

  • Decor: Provide plenty of plants, driftwood, and open swimming areas. Floating plants help diffuse light and reduce stress.

Feeding GloFish Tetras

  • Feed a balanced diet including high-quality flake food or micro pellets.

  • Supplement with live or frozen foods like brine shrimp, daphnia, and bloodworms for enhanced health and color.

  • Feed small amounts 2 times daily.

Behavior and Tankmates

  • GloFish Tetras are peaceful and do well in community tanks with other small, non-aggressive fish such as guppies, rasboras, and other tetras.

  • Avoid large or aggressive species that may intimidate or eat them.

Breeding GloFish Tetras

  • Breeding GloFish Tetras is similar to Black Skirt Tetras, but their fluorescent trait may vary in offspring.

  • Provide soft, slightly acidic water and spawning plants or mops.

  • Remove adults after spawning to protect eggs and fry.

  • Fry require tiny foods such as infusoria or specially prepared fry food.

Final Thoughts

The GloFish Tetra adds a splash of electric color and lively energy to any freshwater tank. Their stunning fluorescent glow and peaceful nature make them a favorite for aquarists wanting to create a visually striking and vibrant community aquarium.
