Neon Tetra Origin and Habitat in the Wild
Neon Tetra was discovered by August Rabaut, a French traveler during his expedition around the Amazon Jungles. Europeans became a big fan of neon tetra when August Rabaut brought them to Europe for sale.
Neon Tetra (Paracheirodon innesi) lives in the Blackwater stream and tributaries in the Western and Northern Amazon and Orinoco basin in Brazil, Columbia, and Peru.
These streams are full of driftwoods and plants as if nature itself created the art of aquascape for the fish.
Neon tetra spends most of the time roaming around these plants and driftwoods, which also gives some sort of protection and hiding place from its predator.
In the wild, they live in the middle of the slow stream water, where they feed on insects, worms, and small creatures.
Neon tetras are schooling fish, so they swing together in a tribe with energetic movement that creates a magnificent display of its color.
Neon Tetra lives around eight years in their natural habitat. However, they generally live for five years in the aquarium.
It is usually found in water, having a temperature of 20 and 28 °C (68-82 °F) and a pH of 4-7.5. It is not found in the white-water Rivers.
They are peaceful, non-aggressive fish, which makes them a fantastic addition to the community tank and is a great tank mate for almost all fishes that are mostly non-aggressive.
They tend to fill up the aquarium and usually swim in the middle of the water column. In the wild, it lives around eight years, and in captivity, its lifespan is about five years only.
Neon Tetra Distribution

Neon Tetras are bred and brought up in captivity of Eastern Europe and the far east to fulfill the demand of aquarists worldwide. Less than 5 percent of Neon Tetra you see in the market is wild-caught.
Today, due to its popularity, some countries like Hong Kong, Thailand, and Singapore have also started captive breeding trade.
More than 1.50 million Neon tetras are imported to the United States each month.

Like humans, fish also gets attracted to bright colors, so as for neon tetra, it is essential to choose non-aggressive tankmates.
Likewise, because of their little body, the fish should not be kept with any fishes that can fit them in their mouth, predatory fishes should be strictly avoided.
Choosing tankmates for neon tetra is a tricky part, if you keep them with the wrong fish, your neon tetra will definitely get killed.
The best tank mates for Neon tetra is neon tetra itself. These neon tetras are schooling fish and will do well in the presence of their own kind.

Neon Tetra Diet and Feeding
Food is an essential factor in surviving, whether it’s for humans or animals.
Maintaining a proper diet in day-to-day life can be a difficult task, especially when you don’t have enough time for your fish.
Just like the human body need a certain amount of diet to function, this tetra also needs a proper diet if you don’t want to see them suffer and die.
Although Neon tetras can go without food for a week, you need to make sure not to push their limit or experiment with no food.
Maintaining a diet for Neon tetra is not a difficult task as Neon tetras are omnivorous, which means they will eat both meat and vegetables.
They accept any form of food that you provide them. All you need to do is to take care of the nutrients.
In their natural habitat, their primary diet relies on small insects, algae, and other minuscule invertebrates.
But in your aquarium, you need to provide them good food. Feed them with fine flakes food, tiny granules, pellets, Brine Shrimp, blood worms, and other forms of fish food like live worms, daphnia, and tubifex once in a while this will give enough nutrients to the fish to be healthy.
The tetras would love these, and they are supplemented evenly to help them with attaining their vibrant colors.
They are comparatively little to swallow and ingest the food, so they should be fed with small pellets.
Neon Tetra Disease
Fish do get sick and sometimes die without any trace.
This is something that every fish keeper needs to know that will help them to take adequate measures.
Unluckily, Neon Tetra suffers from one deadly disease that is caused by the Microsporidian parasite. The disease is called Neon Tetra Disease, as this disease was first discovered in Neon Tetras. Once the fish is infected with the parasite, it will literally eat the fish inside out.
The diseases can also spread quickly and attack other tetras, as well as fish from other breeds.
Symptoms Of Neon Tetra Disease
- The colors on the fish body slowly fade away, which is often seen on one part of the body.
- Fish infected with Neon Tetra Disease will have trouble swimming and can turn into a bottom dweller.
- Neon Tetra Disease causes a curved spine and a shrunken stomach.
- Swollen and rotten fins.
- Develop cysts on the stomach area as the body begins to have lumps.
Prevention Of The Disease
There is no cure for the Neon Tetra disease to date. If your fish catches this disease, then it will spread all over the tank and kill other fish. So, it’s better to separate the fish infected with NTD.
“Prevention is better than cure.”
- Whenever you buy a new fish, quarantine them first. Look for any strange behavior before adding them to your display aquarium.
- Avoid purchasing sick fish from the store.
- Always maintain your water quality properly.
- Always buy fish from trustworthy suppliers. However, if you are buying fish online, then make sure to check the reviews.

Aquarium Care For Neon Tetra
Neon Tetra is such a wonderful striking fish and the first pet fish for a lot of people. Anyone can fall in love with neon tetra at first glance.
You will require an intermediate fish keeping skill to keep Neon Tetra. Although neon tetras are hardy fish, they still require some care.
There are few things Neon tetras need in their tank to survive and live healthily and it’s your duty to give them that.
You will need a good-sized aquarium, lightings, filtration system, substrate to make them feel at home in your aquarium.
As it is necessary to know how to take care of neon tetra in a tank, here are some things you need to know to keep them happy.
Tank Size For Neon Tetra
Most beginner aquarists make a mistake while choosing an aquarium. No matter what fish you choose, you will always need a bigger tank than the fish requirement. This gives enough room for you to play with, like adding decorations and all.
You need to be extra careful with neon tetras and know the best tank size for Neon tetras. You also have to know how many neon tetras to keep per gallon of water in the tank.
Neon Tetras are schooling fish so you need to remember this while choosing an ideal tank. For Neon Tetras, if you are planning to keep five or six of them in a school, a 20-gallon tank is enough. However, if it’s a community tank, you need to go for a bigger tank at least 40-Gallon.
Let me give you an example: one inch of fish requires 2 gallons of water to survive, if you have five fish that are 2 inches long, then you need to have at least a 20-gallon aquarium to house them.
Neon Tetras are schooling fish, they move in a group, and requires a bigger area to swim freely. So, bigger is always better.
Water Parameters For Neon Tetra
Just like we humans need fresh air, fish also need fresh and clean water to survive.
Neon tetras are sensitive to the environment they live in. So, you need extra care while keeping these tetras. Do not add your neon tetra into the tank you just set up the day before or on the same day. Let the water in the tank mature so that it will be suitable for your fish. You can find chemicals and good bacteria in your pet store to speed up the maturing process that takes place as the Aquarium Nitrogen Cycle.
Water Temperature, pH, and Hardness For Neon Tetras
You need to maintain the water temperature for your Neon Tetras well. The best water temperature for Neon tetra is between 70°F and 81°F.
The room temperature cannot help you attain the tropical temperature these tetras ask for. That’s why Neon tetras needs an aquarium heater for their survival in the tank environment.
Use a good quality aquarium heater that has an automatic feature. These heaters will automatically adjust the water temperature in your aquarium.
Hitop Submersible Adjustable Aquarium Heater is highly recommended for your neon tetra tank. All you need to do is set the water temperature and plug the heater on.
Likewise, the change in water pH level can affect your Neon tetras bringing various health issues and diseases. You need to keep a pH level below 7.0 and above 6.0.
Also, always maintain soft water or slightly acidic water (<10 dGH) in your aquarium. Simple things can make a huge impact on these small fish even though they are hardy.
Maintaining Water Quality For Neon Tetras
You will need to maintain the aquarium water quality. As the aquarium is a closed system, the pollutants will stay in the aquarium unless you clean them.
The best way to maintain your aquarium water is to use a good quality aquarium filter for Neon Tetras to survive. And do at least 10% water change every week.
You can find chemicals in your pet store that are sold as aquarium water cleaners or purifiers. I would not recommend using those chemicals in your tank. Let the tank be as organic as possible. If you can eliminate these chemicals and waste just by changing your water, why would you spend an extra buck on these useless chemicals?
Changing water will not only help to eliminate waste and chemicals but will also help to maintain pH and water hardness. You need an aquarium kit to check and maintain your pH between 6 – 7 and water hardness less than ten dGH.
Neon Tetra fish can deal with the hardest water for maximum ranges of time. However, the introduction of the fish to hard water could have a negative effect on their life expectancy. It is recommended to use soft water.
Water Filtration For Neon Tetras Tank
Aquarium filter is a helping hand when it comes to maintaining your aquarium water.
Since neon tetras have a very small load, any basic or JOR Neon Tetra Sponge Filter will be sufficient for the aquarium. Neon tetras should always be added to a properly cycled tank.
Lighting Of Neon Tetra Tank
In the wild, Neon Tetras are found in the black water streams, where only some amount of light gets through the water. Therefore, too much light will stress the neon tetra, opening the door to various fish diseases.
Moderate lighting is enough for the fish and will pop its body color in a darker environment with little lights on.
However, if you want to keep neon tetra in a tank with live plants, get the light that is suitable for your plants.
Since planted aquarium has a lot of hiding places, they can find spots to hide out if they are frightened or stressed.
Tetra Fish Tank Kit comes with LED lighting and décor to make your work easier while setting the tank.
Aquarium Decoration and Substrate For Tank With Neon Tetras
Fish in an aquarium with just water looks so unattractive and unnatural. You should provide some plants in the aquarium where fish can play or hide.
Live plants will help in keeping the aquarium water parameter stable. Plants use nitrogen as a fertilizer that is harmful to fish and provides oxygen for them to breathe.
Go with the plants such as Ludwigia repens, Brazilian pennywort, Vallisneria, Cabomba, or Cryptocoryne wendtii.
Tetra fish will go into plants when they will feel threatened. They will swim around in the plants when they try to avoid any threat.
It’s always nice when you add some plants to the tank. They add a touch of beauty to the tank and also provide proper filtration.
Fake plants also can be used as an option. Black sand would be the substrate to go for as it brings out the bright colors of neon tetra to the fullest.
In case you don’t have those plants, use some dead leaves, rocks, woods, and fake plants. Tetra Fish Tank Kit comes décor to make your work easier while setting the tank.
Neon tetras can live on anything ranging from gravel to sand when it comes to the substrate. They are not bottom dwellers so they won’t even mind having a bare bottom.
But as these tetras love having plants in their tank, you have to go for plant growing substrate. You need to go for substrates that provide proper grip and nutrients for the plants.
Also, a black-colored substrate can be used in the tank with neon tetras as it helps to darken the tetra tank mimicking their natural habitat.
Breeding The Neon Tetra
Not all people breed their fish, especially beginners.
In the case of breeding, there are lots of things you should know about the Neon tetra as they can be challenging fish to breed.
Neon tetras can be challenging to breed because of the requirement for specific water conditions. To breed them, we must set up a different tank.

Water hardness in the specific breeding tank should be just 1 to 2dGH, and pH should be monitored and be kept between 5.0 to 6.0.
Use gentle filter, and providing them with live plants are suitable. They tend to jump during their breeding rituals, so the tank should be properly covered with no gaps.
Covering the side panels of the tank with a cover to decrease the light in the tank is also great. Water temperature should be kept somewhere in the range of 72 and 75 °F (24 °C).
So, let’s get into the process while breeding the Neon tetra and what are the neon tetras growth stages.
The most accurate way to differentiate male and female neon tetra is to look at its stomach.
In the spawning time, female neon tetra will have a rounded belly as they have to carry eggs, whereas males will have a thinner body.
The blue line in males appears to be straight, whereas due to the rounded body, it’s a bit curvy in the female’s body.
Setup The Breeding Aquarium For Neon Tetras
During the time of breeding, set up a separate breeding tank for the fish as they will get disturbed by other species on a community tank.
The Breeding Tetra Tank
To breed neon tetras, one should place the breeding pair in a breeding tank with no light. It’s better to cover your aquarium with a newspaper so that the fish won’t get disturbed by people moving around the aquarium.
Remember to use tank cover as swapping fish often jump during the breeding time. Pace the swapping mops on the bottom of the tank and put the aged sponge filter in as well, with just a tickle of air running.

Water Condition For Neon Tetra Breeding Tank
Neon tetra breeds best in soft acidic water so you can either collect rainwater or use reverse osmosis water.
You also need to maintain the water hardness in the breeding tank, which should be only 1 to 2 dGH, and pH 5.0 to 6.0.
After that, set the heater to 72 to 75 °F to maintain the water temperature that will help for the Neon tetra to feel like its natural environment.
Tank Décor Of The Tetra Breeding Tank
For successful breeding, keep more hiding places in the tank with some plants, driftwoods, and pots. Neon Tetras are egg scatters.
The female lays the egg first that sticks to plants, which are then fertilized by the male. It is better to use plants like moss in the breeding tank
Diet For Neon Tetras During Breeding Period
People will get confused about whether to feed them during the breeding time or not. It’s ok to feed them.
Good nutrition food such as blood worms, brine shrimp is a must for a healthy fry. Feed Neon tetra twice a day, which will promote them to breed.
Maintain Water Quality In The Breeding Tank
Don’t let the water of the aquarium stay for too long. Change 25%-50% of tank water every week to maintain the quality of water. Make sure to check the water condition and quality once a week to ensure everything is ok.
Breeding Process Of Neon Tetras
After the breeding, the tank is set correctly, and the breeding pair is chosen. They tend to breed as soon as they acclimate to their new environment.
Once the egg is fertilized, you need to remove the young fish from the tank. Neon tetra does not care for their eggs or the fry. They will eat them all without any hesitation.
Caring For The Fry Of Neon Tetras
The egg of Neon tetra will hatch within 24 hours, and you will able to see little fry inside your aquarium.
They will be able to swim freely in the next 2 to 3 days. You should not feed the newly hatched neon tetra fry.
Adding food to their tank will only degrade the tank water risking their life. Once they are able to swim freely, you can decrease the level of water to 7-8 centimeters height and make sure there isn’t any slime on the surface of the water since these tiny neon tetra needs to fill up their air bladder with fresh air.
Once they start to swim, you need to feed them a minimal amount of food. Foods such as egg yolk, infusoria, and commercially prepared fry food are the best.
Excess food and uneaten food can spike the ammonia level in the water killing all of your tiny neon tetras. You will need to remove any uneaten food from the tank.
You could also use an aquarium filter best suited for tetra fish fry like the sponge filter to maintain water quality in the tank.
Note: Do not expect more fry from eggs as the hatch rate is not that high.
Fact: “A small school of Neon tetra can produce hundreds of eggs a week.”
