Glow Neon Tetra Overview

Glow Neon Tetras are a species of freshwater fish originating from South America, specifically from the Amazon basin. They are a smaller species, growing to an average size of about 1.5 inches (3.8 cm) in captivity. What sets them apart from their non-glowing counterparts is their remarkable bioluminescence. These fish exhibit vibrant neon colors, primarily consisting of blue and red hues, creating a visually stunning display in your aquarium.

Bioluminescence in Glow Neon Tetras

The captivating glow of Neon Tetras is a result of specialized cells called chromatophores, which contain pigments and reflect light. These cells are more pronounced in certain areas of their bodies, such as their fins and adipose tissue. Under the right conditions, the pigments in these cells emit a mesmerizing glow, making these fish a true spectacle to behold.

Tank Setup for Glow Neon Tetras

Tank Size and Parameters

When setting up a home for your Glow Neon Tetras, it’s essential to provide them with an environment that mimics their natural habitat. Here are some key considerations:

  • Tank Size: A minimum tank size of 10 gallons is recommended for a small group of Neon Tetras. However, larger tanks are better, as they allow for more swimming space and a more stable environment.
  • Water Temperature: Maintain a stable temperature between 72°F and 78°F (22°C to 26°C). Neon Tetras are sensitive to temperature fluctuations, so a reliable heater is essential.
  • pH Level: Aim for a slightly acidic to neutral pH level between 6.0 and 7.0.
  • Water Hardness: Keep the water hardness in the range of 2 to 10 dKH.

Substrate and Decorations

Glow Neon Tetras thrive in planted tanks with plenty of hiding spots and swimming spaces. Here are some tips for decorating their habitat:

  • Substrate: Use fine gravel or sand as the substrate. This mimics their natural environment and is gentle on their delicate fins.
  • Plants: Incorporate live or silk plants into the tank to provide cover and create a natural-looking habitat.
  • Driftwood and Rocks: Adding driftwood and rocks can enhance the aesthetics of the tank and provide additional hiding spots.


Achieving the perfect lighting conditions is crucial to bring out the neon glow of these fish. Opt for subdued lighting with a timer to simulate the natural day-night cycle. This helps in reducing stress and enhances their coloration.

Glow Neon Tetra Care


Glow Neon Tetras are omnivorous and have a small mouth, so it’s essential to provide them with appropriately sized food. Their diet should consist of:

  • High-quality Flake or Pellet Food: A staple in their diet, choose a food specifically formulated for tetras.
  • Live and Frozen Foods: Offer occasional treats like brine shrimp, daphnia, and bloodworms to diversify their diet and enhance their coloration.
  • Vegetables: Infrequently, you can offer blanched vegetables like spinach or zucchini for added nutrition.

Tank Mates

Glow Neon Tetras are peaceful by nature, making them excellent community tank residents. However, it’s crucial to choose tank mates wisely. Compatible species include:

  • Other Tetras: Neon Tetras thrive in the company of their own kind or other small tetra species like Cardinal Tetras and Ember Tetras.
  • Corydoras Catfish: These bottom-dwelling catfish make great companions as they are peaceful and help keep the tank clean.
  • Small Gouramis: Dwarf Gouramis and Honey Gouramis are suitable choices due to their non-aggressive nature.

Water Quality Maintenance

Maintaining pristine water quality is paramount for the health and well-being of Glow Neon Tetras. Regular water changes of 20-25% every two weeks, along with proper filtration, are essential. Ensure that the water parameters remain stable to prevent stress and diseases.

Breeding Glow Neon Tetras

Breeding Glow Neon Tetras can be a rewarding endeavor for experienced hobbyists. Here’s a brief overview:

  • Separate Breeding Tank: Set up a separate breeding tank with fine-leaved plants for the females to lay their eggs.
  • Conditioning: Prior to breeding, feed high-quality foods and maintain optimal water conditions to ensure the health of the breeding pair.
  • Egg Scattering: Glow Neon Tetras are egg scatterers, meaning they do not provide parental care. The eggs will attach to plants and hatching typically occurs within 24-36 hours.
  • Rearing Fry: After hatching, provide tiny food options like infusoria or commercial fry food for the fry’s initial growth stages.

Glow Neon Tetra Tank Mates
Choosing the right tank mates for Glow Neon Tetras is crucial to ensure a harmonious aquarium community. These peaceful fish thrive when paired with compatible species. Suitable tank mates include other small tetras like Cardinal Tetras and Ember Tetras. Additionally, non-aggressive bottom-dwellers like Corydoras Catfish make excellent companions. Avoid aggressive or fin-nipping species that can stress out your Neon Tetras.

Glow Neon Tetra Male or Female
Distinguishing between male and female Glow Neon Tetras can be a bit challenging. Both sexes share similar characteristics, but females are typically slightly plumper when they are carrying eggs. During breeding, males may appear more slender, and females may exhibit a rounder belly. Otherwise, their colors and fin shapes are quite similar, making it challenging to differentiate them outside of the breeding context.

Glow Neon Tetra for Sale
Glow Neon Tetras are readily available in most pet stores and online aquarium retailers. You can purchase them individually or as part of a school. Ensure you buy from reputable sources that provide healthy, well-cared-for fish. Always check for signs of good health, such as vibrant colors and active swimming, when making a purchase.

Glow Neon Tetra Price
The price of Glow Neon Tetras can vary depending on several factors, including their size, coloration, and where you purchase them. On average, you can expect to pay around $1 to $3 per fish. Rare color variations or larger specimens may command a higher price. Shopping around and comparing prices from different suppliers is a good practice to ensure you get a fair deal.

Caring for GloFish Tetras is similar to caring for their non-genetically modified counterparts. They require suitable tank conditions, proper nutrition, and compatible tank mates. The primary distinction lies in their vibrant fluorescent colors, which add a unique aesthetic to your aquarium.

GloFish Tetra Care Sheet
A GloFish Tetra care sheet is a valuable resource for aquarists looking to provide the best possible care for these genetically modified tetras. It typically includes information on tank setup, water parameters, feeding, and more, tailored specifically to the needs of GloFish Tetras.

GloFish Tetra Care for Beginners
GloFish Tetras can be a great choice for beginners due to their hardiness and ease of care. They thrive in well-maintained aquariums with stable water conditions. Novice aquarists should focus on providing them with proper nutrition, a suitable tank size, and compatible tank mates.

GloFish Tetra Tank Size
A suitable tank size for GloFish Tetras depends on the number of fish you plan to keep. For a small group of GloFish Tetras, a tank size of 10 to 20 gallons is sufficient. Larger tanks provide more swimming space and can accommodate a larger community of these colorful tetras.

Do GloFish Need Light at Night
GloFish Tetras do not require light at night. Like most fish, they benefit from a consistent day-night cycle. It’s advisable to provide a period of darkness during the night to mimic their natural environment and promote their well-being.

GloFish Tetra Lifespan
GloFish Tetras have a similar lifespan to their non-modified counterparts. On average, they can live for about 3 to 5 years with proper care. Ensuring a suitable tank environment, a balanced diet, and a stress-free atmosphere can contribute to a longer and healthier life for these captivating fish.

GloFish Tetra Food
Feeding GloFish Tetras is straightforward. They are omnivorous and readily accept high-quality flake or pellet food. Additionally, offering occasional treats like freeze-dried or frozen foods such as bloodworms or brine shrimp can enhance their diet and coloration.

Do GloFish Need a Heater
GloFish Tetras, like many tropical fish, thrive in a stable and warm environment. To maintain the recommended water temperature of 72°F to 78°F (22°C to 26°C), it’s advisable to use a reliable aquarium heater to ensure the well-being of your GloFish Tetras.
