Purple Glo Tetra

1. Physical Characteristics

• Coloration: The Purple Glo Tetra has a bright, neon purple body that glows under blue LED lighting, making it a standout addition to any aquarium. This vibrant color is achieved through genetic modification, specifically the introduction of fluorescent proteins.
• Size: They typically grow to about 1.5-2 inches (4-5 cm) in length.
• Lifespan: With proper care, Purple Glo Tetras can live for 3-5 years in captivity.

2. Natural Habitat and Distribution

• Origin: While the original tetra species are native to South America, the Purple Glo Tetra is a genetically engineered variant and does not have a natural habitat. It is based on species like the Gymnocorymbus ternetzi (Black Tetra).
• Tank Environment: In captivity, they thrive in well-planted aquariums that mimic their natural habitat, providing both shaded areas and open swimming spaces.

3. Behavior and Temperament

• Peaceful Schooling Fish: Purple Glo Tetras are social fish and should be kept in groups of at least 6-10 individuals. They are active swimmers, often seen schooling together.
• Social Behavior: Generally peaceful, they can exhibit mild territorial behavior during breeding but are not aggressive. Their vibrant colors tend to become more pronounced when kept in groups.

4. Aquarium Care

• Tank Size: A minimum tank size of 10 gallons is recommended for a small school of Purple Glo Tetras. A larger tank (20 gallons or more) is preferable to provide ample swimming space and stability in water conditions.

  Water Parameters:

  • Temperature: 70-78°F (21-26°C).

  • pH: 6.0-7.5 (slightly acidic to neutral water).

  • Water Hardness: 4-12 dGH (soft to moderately hard water).

  • Filtration and Aeration: They prefer well-oxygenated water, so a good filtration system is essential. Gentle water flow is ideal.

• Aquascaping: Provide open swimming areas along with dense planting using soft-leaved plants like Java fern, Amazon sword, and floating plants. Incorporating driftwood and rocks can create hiding spots and enhance the overall environment.

5. Diet

• Omnivorous: Purple Glo Tetras are omnivores and require a varied diet.

  Diet Options:

  • High-quality flake or pellet food formulated for tropical fish.
  • Live or frozen foods such as brine shrimp, bloodworms, and daphnia.
  • Plant-based foods, including spirulina and algae wafers, to ensure balanced nutrition.

  Diet Variation: A diverse diet helps maintain their health and enhances their coloration.

6. Breeding

• Egg-Laying Species: Breeding Purple Glo Tetras in captivity can be successful under the right conditions. They are egg scatterers and prefer spawning in soft, well-planted areas.
• Mating Behavior: Males may display more vibrant colors during breeding and can be seen courting females with swimming displays.
• Hatching: Eggs usually hatch in about 24-36 hours. Once the fry are free-swimming, they should be fed infusoria or specialized fry foods until they are large enough to eat baby brine shrimp or finely crushed flakes.

7. Tank Mates

• Compatible Tank Mates: Purple Glo Tetras are generally peaceful and can be housed with other similarly sized, non-aggressive species.

  Good tank mates include:

  • Other small tetras (such as Neon Tetras or Rummy Nose Tetras).
  • Rasboras, including Harlequin or Scissortail Rasboras.
  • Corydoras catfish, small loaches, or other peaceful community fish.

  Avoid Aggressive Fish: Larger or aggressive species should be avoided, as they may stress the Purple Glo Tetras or compete for food.

8. Fun Facts

• Fluorescent Glow: The Purple Glo Tetra's bright color is enhanced under blue light, making them a popular choice for aquarists looking to create visually striking displays.
• Community Favorites: Due to their unique appearance and easy care, Purple Glo Tetras are popular choices for community tanks and nano aquariums.
• Genetic Modification: Unlike traditional tetras, Purple Glo Tetras are genetically engineered, raising discussions around ethical considerations in fishkeeping.

9. Importance in Aquariums

• Visual Appeal: Their bright colors and active behavior make them a standout species in community tanks.

• Beginner-Friendly: Purple Glo Tetras are relatively easy to care for and can thrive in a variety of setups, making them suitable for both novice and experienced aquarists.

  Key Care Tips:

  • Stable Water Conditions: Regular water changes and good filtration are crucial for their health and overall appearance.
  • Group Size: Keep them in schools of 6-10 or more to encourage natural behaviors and enhance their vibrant coloration.
  • Balanced Diet: A varied diet with both plant and protein-based foods will help them maintain their health and overall appearance.
