In the wild, Glowlight Tetras live in big groups, known as shoals or schools, and they feed on small insects, worms, and other tiny creatures that live in the water. These days, you can find Glowlight Tetras in aquariums all around the world because they’re bred in captivity. Just be sure to buy them from a reputable source so you can be sure they’ve been raised in healthy conditions!
Glowlight Tetras are small fish that can add a big pop of color to your aquarium. They’re called “glowlight” because of their bright, almost fluorescent orange color. It’s really hard to miss them when they’re swimming around! If you look closely, you’ll also notice a contrasting black stripe that runs horizontally down their sides, which is what sets them apart from other tetra species.
Their fins are just as delicate and stunning as their body. The dorsal fin, located on their back, is tall and triangular in shape. It’s transparent, and if you look closely, you’ll see tiny little bones that give it structure. The anal fin, located on their belly, is long and pointed, and it also has a translucent quality that makes it look almost ethereal. Finally, the adipose fin, located on their back between the dorsal and tail fins, is small and rounded, and it doesn’t really serve any purpose other than to look cute.
Overall, the combination of their vibrant orange body and their delicate, translucent fins make Glowlight Tetras a great addition to any aquarium. When they swim around, their fins move gracefully through the water, making them a pleasure to watch.
Behavior and Temperament
Glowlight Tetras are known for their peaceful and social nature. They’re very active fish and love to swim around, exploring their environment. They can usually be found darting back and forth through the plants, or playing tag with their tank mates.
One thing to keep in mind about Glowlight Tetras is that they can be a bit skittish. They may get startled by sudden movements or loud noises, causing them to swim frantically around the tank. However, they quickly settle back down once they feel safe.
Glowlight Tetras are schooling fish, meaning they should be kept in groups of six or more. When they’re in a group, they’re more confident and less stressed. They tend to be more active and display their natural behaviors when they feel secure in their environment.
They’re also are easy-going fish that make great additions to any peaceful community aquarium. They get along with most other non-aggressive fish and enjoy having plenty of space to swim and play.
Glowlight Tetras are peaceful fish that get along well with most other non-aggressive species. When choosing tank mates for your Glowlight Tetras, it’s important to make sure that the other fish have similar temperaments and water requirements.
Some good tank mates for Glowlight Tetras include:
- Other peaceful tetra species, such as Neon Tetras, Green Neon Tetras, Cardinal Tetras, and Ember Tetras
- Small catfish, such as Corydoras or Otocinclus
- Guppies, Platies, and other livebearers
- Shrimp, such as Cherry Shrimp or Ghost Shrimp
Avoid keeping Glowlight Tetras with aggressive or fin-nipping fish, such as Cichlids, Bettas, or Barbs. These types of fish may see the Glowlight Tetras as prey or competition, leading to stress and potential injury.
It’s important to note that even though Glowlight Tetras are peaceful, they still need plenty of space to swim and hide. Overcrowding can lead to stress and disease, so be sure to provide enough room for all of your fish to swim comfortably.
Glowlight Tetra Care
If you’re thinking about adding Glowlight Tetras to your aquarium, it’s important to create a suitable environment for them to thrive in. Here are some key factors to consider when setting up your tank:
Glowlight Tetras are small fish, but they still need plenty of space to swim and play. A good rule of thumb is to provide at least 10 gallons of water for a school of 6 to 8 Glowlight Tetras. This gives them enough room to swim around and establish their territory without feeling cramped.
What to Put in the Tank
Glowlight Tetras are natural explorers and love having plenty of hiding places and things to swim around. A well-planted tank with plenty of hiding spots, such as caves, rocks, and driftwood, will make them feel more secure and less stressed. When choosing plants for your tank, be sure to select varieties that are compatible with your water parameters.
Glowlight Tetras are generally hardy fish that can adapt to a range of water conditions, but they still have specific requirements for optimal health and well-being. Maintaining good water quality is crucial for the health of your Glowlight Tetras, as they can be sensitive to changes in their environment. Here are some key parameters to consider:
- pH: 6.0-7.5
- Temperature: 75-80°F (24-27°C)
- Hardness: 5-12 dKH
- Ammonia and Nitrites: 0 ppm
- Nitrates: Less than 20 ppm
- Filtration: A good filtration system is essential for keeping the water clean and free from harmful toxins.
It’s important to monitor the water conditions in your tank regularly, using a test kit to measure the levels of ammonia, nitrite, nitrate, and pH. If any levels are outside the recommended range, it’s important to take action to correct them, such as performing a water change or adjusting the pH level with appropriate chemicals.

Diet and Feeding
Glowlight Tetras are omnivorous fish that will eat a variety of foods in the wild. In captivity, it’s important to provide them with a balanced and varied diet to ensure optimal health and growth.
A good diet for Glowlight Tetras should include a combination of:

- Frozen or live foods: Bloodworms, brine shrimp, and daphnia are good options for providing additional nutrition and variety.
- Vegetables: Fresh or blanched vegetables, such as zucchini or spinach, can also be added to their diet for added nutrition.
It’s important not to overfeed your Glowlight Tetras, as they have a small stomach and can easily become overweight. A good rule of thumb is to feed them small amounts 2-3 times a day, only giving them what they can eat in a few minutes.
In addition to providing a balanced diet, it’s also important to make sure your Glowlight Tetras have a suitable feeding environment. They should have plenty of hiding places to feel secure while they eat, and any uneaten food should be removed from the tank promptly to maintain good water quality.
Like all fish, Glowlight Tetras are susceptible to a range of diseases and health issues. While they are generally hardy and easy to care for, it’s important to monitor them regularly for signs of illness or distress. Here are some common diseases and health issues that can affect Glowlight Tetras:
- Ich (White Spot Disease): This is a common parasitic disease that causes white spots to appear on the fish’s body. It can be treated with medication, but it’s important to catch it early to prevent further spread.
- Fin Rot: This is a bacterial infection that causes the fins to deteriorate and fall off. It can be caused by poor water quality or stress. Treatment includes antibiotics and improving water quality.
