Neon tetras (Paracheirodon innesi) are one of the most popular fish among hobbyists. They’re active, brightly colored, inexpensive, and simple to maintain. Neon tetras are found in the Amazon Basin; however, those in the pet trade are often bred in captivity.
In the wild, neon tetras live around ten years, which is twice the amount for those in captivity. Read how you can provide the tank conditions and care to extend the life of your fish.

What Is the Lifespan of Neon Tetras?
As mentioned before, in the wild, neon tetras can live for up to 10 years; however, their average life span in captivity is only half of that—about two to five years. We can extend their lifespan, however, in captivity if we provide them with the proper tank conditions.
How to Improve Neon Tetra Lifespan?
With today’s knowledge of neon tetras, we can extend the lifespan of these fish by providing them with conditions that closely resemble those in their native land. The first thing to consider involves the purchasing end.
Where you purchase your neon tetras is one factor in extending the life of your fish. Experienced and reputable breeders produce fish with the best genetic quality. Other things you can do to extend their life span include:
- Giving them proper tank conditions
- Maintaining their aquarium according to their needs
- Feeding them appropriate food
- Choosing the right tank mates
- Disease Prevention
What Are the Best Tank Conditions for Neon Tetras?
A properly set up aquarium can make a big difference in prolonging your neon tetra’s life. Tank conditions include tank size, setup, and maintenance.
A 10-gallon aquarium is the minimum size tank for neon tetras. I strongly recommend that you go for a 20-gallon tank. While more expensive, a larger tank will make it easier to maintain stable water conditions.
Because neon tetras are schooling fish, tank dimensions should emphasize length rather than height because neon tetras are schooling fish occupying the water column’s midrange.
Neon tetras are found in the Amazon River Basin, where the water temperature ranges from 69 to 81 degrees Fahrenheit. I recommend purchasing a water heater to maintain the temperature within this range.
This species prefers hard water that is slightly acidic. Water hardness should be between 2 and 10 dkH, while a pH between 6 and 7 is desirable.
Neon tetras are small fish that don’t produce large amounts of waste (bioload). When choosing a
Naturally, if you plan to keep neon tetras as part of a community tank, you’ll want to purchase a
Lighting and Décor
In their natural habitat, neon tetras inhabit slow-moving streams where plenty of organic matter is settled on the bottom. Because of this, the water is murky. For this reason, I recommend you provide the tank with soft lighting. Additionally, this species needs plenty of hiding places to feel secure. Provide dense vegetation in a few areas while leaving the rest as open water for them to swim in. If you’re going for
Whenever keeping aquatic animals, it’s vital that you do partial water changes regularly to maintain safe water conditions for the inhabitants. Animals produce waste in the form of feces and urine. Additionally, uneaten food adds to the mix. These things produce nitrites and ammonia, which are toxic.
As the aquarium ages, beneficial bacteria will colonize the tank. These bacteria convert toxic nitrites into less harmful nitrates. This process is known as the nitrogen cycle. There comes the point, however, when the bacteria cannot keep up with the rising nitrites and ammonia levels.
Doing partial water changes will keep the water from becoming a toxic stew. This should be done by doing a 25% water change weekly. Before introducing fish into the aquarium, ensure your tank has fully cycled. Introducing neon tetras to a tank that hasn’t completely cycled can cause a shock to their system. You can tell that the tank is fully cycled when there are no nitrites or ammonia and the nitrate level is low.
Neon tetras are omnivorous. In the wild, they eat dead vegetation, algae, insect larva, and other small invertebrates. To extend their lives in captivity, offer them the following recommended food items:
- Brine shrimp
- Frozen food
- Quality flake food that contains at least 40% protein.
- Tubifex worms
- Freeze-dried bloodworms
You can also feed them chopped-up cucumbers and grapes.
As neon tetras are active fish, feed them daily. Don’t feed more than they can consume in two minutes.
Neon tetras can make a great addition to a community tank; however, it’s important not to keep them with any fish species that is considered aggressive or semi-aggressive.
Keep Them as a Group
Neon tetras are schooling fish. If they’re not kept as a group, they’re prone to stress and will spend a lot of time hiding. Further, the stress will compromise their immune system, making them more susceptible to disease. For this reason, you should keep neon tetra in a group of at least six individuals. Also, males will become more aggressive during the breeding season and may bully other males. By keeping them in a larger group, no one fish will be targeted by an aggressive male.
Neon tetras do well with other fish of similar size and temperament. The following are suitable tankmates for neon tetras:
- Corydoras catfish
- Otoclinus catfish
- Cardinal tetras
- Black skirt tetras
- Black neon
- Dwarf Gourami
- Clown plecos
- African dwarf frogs
- Ghost shrimp
- Boesemani rainbow fish
Neon Tetra Disease Prevention
Most diseases of neon tetras can be avoided by providing these fish with the proper care and sourcing your fish from a reputable breeder or tropical fish store. The following are some of the diseases that these fish may become inflicted with.
Neon Tetra Disease
Neon tetra disease is caused by Pleistophora hyphessobryconis, a kind of parasite. The spores of this parasite enter the fish’s body. As the disease progresses, cysts will form on the fish’s body. This will give it a lumpy appearance. Other symptoms include:
- Difficulty swimming
- The curvature of the spine
- Discoloration of the body
- Weight loss
The parasite is introduced to the aquarium by feeding live food or adding new fish that haven’t been quarantined. Additionally, fish have been known to become infected by eating dead fish. Because of this, remove any dead fish from the tank as soon as possible.
One way to avoid this disease is to raise your own live food. Raising brine shrimp is simple. Also, ensure that you quarantine fish before introducing them to the aquarium. Some aquarists believe using a diatom
False Neon Tetra Disease
This disease is almost identical to neon tetra disease, as it has the same symptoms; however, this disease is caused by a bacterium rather than a parasite.
A parasitic disease, ich is caused by the protozoan Ichthyophthirius multifiliis. Symptoms include small white spots on the fish’s fins and bodies. Fish inflicted with the disease can often be seen rubbing against rough surfaces to relieve themselves of the irritation.
There’s medication for ich, which you can purchase at a tropical fish store. A home remedy is adding one tablespoon of salt for every five gallons of aquarium water and raising the water temperature by two degrees.
Tail and Fin Rot
Tail and fin rot is caused by poor water quality, and it eats away at the end of the fish’s fins. As the disease progresses, it works its way toward the body, leaving the fins frayed or ragged. Treatment for this disease includes doing a complete water change and adding antibiotics to the water.
Neon Tetra Breeding
Breeding neon tetra can be done, but it ‘s tricky. The main reason for this is that the conditions for their care needs to be on point. When they do breed, they’ll spawn biweekly, but neon tetras don’t provide parental care after laying eggs. The following is the procedure for breeding and caring for young neon tetras.
1. Develop a Food Source
The first step is to set up a culture of infusoria for the fry to feed on. Infusoria is a term for microorganisms such as:
Infusoria can be found in bodies of water; however, the safest source is your aquarium water. Fill a jar with aquarium water and add nutrients to it. Good sources include:
- Banana peel
- Boiled rice
- Powdered cereal
As the infusoria population grows, the water will become cloudy. You can also use a microscope to check for microorganisms. You can then
2. Diet Change for the Parents
To prepare the adults to spawn, provide them with a protein-rich diet. I recommend offering them frozen
3. Create a Breeding Tank
A breeding tank will be needed for the male and pregnant female. The breeding tank needs to have a secured lid as these fish can jump. Also, place a few inches of
Soak peat moss and then spread it across the
When the female lays eggs, remove both parents from the breeding tank. Partial water changes should be done regularly.
