Setting up a Tank
When setting up a tank for Glowlight Tetras, it is important to consider the size of the tank.
A minimum of 10 gallons is recommended for a small school of tetras, but a larger tank is always better.
I personally prefer a 20-gallon tank for my Glowlight Tetras, as it allows them more space to swim and explore.
Proper lighting is crucial for the health and well-being of your Glowlight Tetras. They require a well-lit tank with a light spectrum that mimics natural sunlight.
A good rule of thumb is to provide 1-2 watts of light per gallon of water.
I use a full-spectrum LED light for my Glowlight Tetras, which provides the perfect amount of light for their needs.

It’s a great feeling to see them swimming around and exploring their environment with such enthusiasm!
Tank Mates for Glowlight Tetra
When it comes to selecting tank mates for your Glowlight Tetras, it is important to choose fish that are peaceful and compatible with their gentle nature.
Here are a few options that I have found to work well in my own experience:
- Neon Tetras: These fish have similar water and temperature requirements as Glowlight Tetras and are known for their peaceful nature.
- Cherry Barbs: These fish are colorful and active, but also peaceful and not likely to bother your Glowlight Tetras.
- Corydoras Catfish: These bottom-dwelling fish are a great addition to any community tank and won’t compete with your Glowlight Tetras for food.
It is important to note that some fish should be avoided as tank mates for Glowlight Tetras. Avoid any fish that are aggressive or may nip at the fins of your tetras. Some examples of fish to avoid include:
- Betta Fish: These fish are known for their aggressive behavior and should not be kept with Glowlight Tetras.
- Cichlids: These fish are also known for their aggressive behavior and should not be kept with smaller, peaceful fish like Glowlight Tetras.
Overall, when selecting tank mates for your Glowlight Tetras, it is important to consider their peaceful nature and avoid any aggressive fish that may cause harm.
By choosing compatible tank mates, you can create a beautiful and harmonious community tank that everyone can enjoy.
Personally, I have found that adding a school of Neon Tetras to my Glowlight Tetra tank has been a great addition. The two species swim together peacefully and create a beautiful display of color and movement in my tank.
How Many Glowlight Tetras Should Be Kept Together?
When it comes to keeping glowlight tetras, it’s important to consider how many you should keep together in one tank.
As a general rule of thumb, it’s recommended to keep a minimum of 6 glowlight tetras together. This is because they are social fish and thrive in groups.
Personally, I have found that keeping a larger group of glowlight tetras together is even better. I have a group of 12 in my tank and they seem to be very happy and active.
However, it’s important to make sure that your tank is large enough to accommodate a larger group.
When deciding on how many glowlight tetras to keep together, it’s important to consider the size of your tank.
A 20-gallon tank can comfortably hold a group of 6-8 glowlight tetras. If you have a larger tank, you can keep a larger group of glowlight tetras.
It’s also important to consider the other fish in your tank. Glowlight tetras are peaceful fish and should be kept with other peaceful species.
Avoid keeping them with aggressive fish or fish that are much larger than them.
Overall, keeping a group of glowlight tetras together is the best way to ensure their happiness and well-being. Just make sure to provide them with a suitable environment and compatible tank mates.
I have found that Glowlight Tetras thrive on a varied diet that includes both flakes and live foods.
In the wild, they feed on small insects and crustaceans, so it’s important to provide them with a similar diet in captivity.
High-quality flake foods, such as those made with spirulina and other plant-based ingredients, are a good staple food for Glowlight Tetras.
In addition to flakes, I like to supplement their diet with live or frozen foods, such as brine shrimp, bloodworms, and daphnia.
These foods provide important nutrients and help to keep the fish healthy and active.
I feed my Glowlight Tetras twice a day, once in the morning and once in the evening. This schedule seems to work well for them, but it’s important to adjust the feeding frequency based on the needs of your specific fish.
If you notice that your fish are becoming overweight or underweight, you may need to adjust the amount or frequency of their feedings.
When it comes to feeding Glowlight Tetras, it’s important to avoid overfeeding. These fish have small stomachs and can easily become bloated if they eat too much.
I recommend feeding them only what they can consume in a few minutes, and removing any uneaten food from the tank after feeding.
A good rule of thumb is to feed your Glowlight Tetras an amount of food that is roughly equivalent to the size of their eye. This will ensure that they are getting enough to eat without overfeeding them.
Overall, a varied and balanced diet is key to keeping your Glowlight Tetras healthy and happy.
By providing them with a mix of high-quality flakes and live or frozen foods, and feeding them in moderation, you can help ensure that they thrive in your aquarium.
Health and Maintenance
As an aquarium owner, it’s important to be aware of the common diseases that can affect your Glowlight Tetras.
One of the most common diseases is ich, which is caused by a parasite and can be identified by white spots on the fish’s body.
Another common disease is fin rot, which can be caused by poor water quality or injury and can be identified by frayed or deteriorating fins.
I’ve personally dealt with both ich and fin rot in my own aquarium, and it’s important to act quickly to prevent the disease from spreading to other fish.
Quarantining the affected fish and treating them with medication can help prevent the spread of disease.
If you suspect that your Glowlight Tetras are sick, it’s important to act quickly to prevent the disease from spreading.
There are a variety of medications available to treat common diseases like ich and fin rot.
Follow the instructions carefully and be sure to remove any activated carbon from your filter before adding medication to the aquarium.
It’s also important to maintain good water quality and perform regular water changes to prevent the spread of disease. Keeping the aquarium clean and well-maintained can go a long way in preventing illness in your fish.
The best way to prevent disease in your Glowlight Tetras is to maintain good water quality and keep the aquarium clean.
Perform regular water changes and test the water regularly to ensure that the levels of ammonia, nitrite, and nitrate are within safe levels.
Quarantining new fish before adding them to the aquarium can also help prevent the spread of disease. It’s important to observe new fish for any signs of illness before adding them to the main aquarium.
Cleaning and Maintenance
Regular cleaning and maintenance of the aquarium is crucial for the health of your Glowlight Tetras.
Perform weekly water changes of 25% to 50% to remove any excess waste and maintain good water quality.
Clean the aquarium glass, decorations, and filter regularly to prevent the buildup of algae and debris.
Be sure to use a gentle cleaner and rinse everything thoroughly before returning it to the aquarium.
By following these simple steps, you can help ensure the health and longevity of your Glowlight Tetras.

It’s important to note that even if your glowlight tetra is exhibiting all of these signs, regular check-ups with a veterinarian specializing in aquatic animals is recommended to ensure their continued health and well-being.
Personally, I always make sure to observe my glowlight tetras closely and keep track of their behavior and appearance.
It’s a great way to catch any potential health issues early on and ensure my fish are happy and healthy.
Signs of a Sick Glowlight Tetra
As a fish owner, it is important to keep an eye on your glowlight tetra’s behavior and appearance. Here are some signs that your glowlight tetra may be sick:
- Loss of appetite: If your glowlight tetra is not eating or appears to be eating less than usual, it may be a sign of illness.
- Unusual swimming behavior: If your glowlight tetra is swimming erratically, such as swimming upside down or sideways, it may be a sign of a swim bladder issue.
- Discoloration: If your glowlight tetra’s color appears faded or dull, it may be a sign of illness or stress.
- Clamped fins: If your glowlight tetra’s fins are clamped against its body, it may be a sign of stress or illness.
- Gasping for air: If your glowlight tetra is gasping for air at the surface of the water, it may be a sign of poor water quality or a lack of oxygen in the tank.
If you notice any of these signs in your glowlight tetra, it is important to take action quickly to address the issue.
It may be helpful to consult with a veterinarian or a fish expert to determine the best course of action.
I remember when my glowlight tetra started swimming upside down. I was worried and didn’t know what to do.
After consulting with a fish expert, I learned that it was likely a swim bladder issue and was able to take the necessary steps to help my fish recover.
It’s important to pay attention to your fish’s behavior and take action when necessary to ensure their health and wellbeing.
Glowlight Tetras are egg scatterers and breed in groups. During mating, males will chase females around the aquarium and perform a courtship dance.
The female will lay her eggs, and the male will fertilize them. It’s important to have a good ratio of males to females to ensure successful breeding.
How to Know if a Glowlight Tetra is Pregnant
Unlike some other fish species, it can be difficult to tell if a glowlight tetra is pregnant.
However, if you notice a female has become rounder in the belly area, it’s possible she’s carrying eggs.
Females will also become more reclusive during this time and may hide in plants or decorations.
Breeding Tank Setup
If you’re planning to breed glowlight tetras, it’s recommended to set up a separate breeding tank.
The tank should be at least 10 gallons and have plenty of plants for the female to lay her eggs on. A sponge filter is a good choice for filtration as it won’t suck up any eggs or fry.
Egg Laying and Care
Once the female lays her eggs, it’s important to remove the adults from the breeding tank to prevent them from eating the eggs.
The eggs will hatch in about 24-36 hours, and the fry will become free-swimming a few days later. It’s important to keep the water clean and well-oxygenated during this time to ensure the fry’s survival.
When the fry are free-swimming, they can be fed infusoria or baby brine shrimp. As they grow, you can gradually increase the size of their food.
It’s important to keep up with regular water changes and monitor the water parameters closely to ensure the fry’s health. Within a few weeks, the fry will start to resemble adult glowlight tetras and can be moved to a larger tank.
Personally, I found breeding glowlight tetras to be a rewarding experience. It’s amazing to watch the whole process unfold, from the courtship dance to the hatching of the eggs. With a little patience and care, anyone can successfully breed these beautiful fish.
