Well, if you did not know, the bright coloration of the Tetras are not just for nothing!

Additionally, you may already know that the Neon Tetra originated from the Amazon river basins of South America. So, people import more than 1.8 million Neon Tetras from the US every year for petting purposes. That is why the neon tetra is the perfect pet for you.

However, many fish hobbyists in the world have bred these fish by using selective breeding processes too. If you did not know, buying a selectively bred Neon Tetra fish is better than bringing the wild Neon Tetra for your fish.

Fact #7: Mimic The Natural Environment

You already know that the Neon Tetras belong to the blackwater mainstreams of the Amazon basins of South America. So, if you wish to keep them in captivity, it is best to mimic their natural environment too.

All you need to do is to find the best suitable plants and substrates for your Neon Tetra. Keep both natural and artificial substrates so that your Neon Tetra will feel more homely.

Furthermore, you need to take proper care of the tank conditions and water parameters for Neon Tetra as well. The best tank size for the Neon Tetra is 10 to 30 gallons. Tetra Aquarium 20 Gallon Fish Tank Kit, Includes LED Lighting and Decor would be the best choice.

However, the tank size depends upon the number of fish that you keep too. I think you know about this already. The adequate water temperature for the Neon Tetra is between 72 to 80 degrees Fahrenheit. The PH level is between 6 to 7. The DH level should be less than one. In other words, Neon Tetras prefer soft, lightly acidic, and dark water.

Fact #8: Delicate And Sensitive

Like we are sensitive to seasonal and water changes, the same is the case with the Neon Tetras. These fish are super sensitive to extreme water and temperature changes.

As I mentioned earlier, these fish love black waters with slightly hot temperatures. But I did not mean to say that you should keep extreme water degrees either. I have already explained about the adequate water temperature above.

Forget about vast differences because even slight changes can affect your Neon Tetra. Even though the Neon Tetras are hardy, they can’t tolerate changes in water chemistry and temperatures. The fish may suffer and stress out, which leads them to vital diseases. Thus, Neon Tetras are delicate and sensitive.

Fact #9: Omnivorous Diet

Neon Tetras are Omnivores as they eat both vegetables and meat in the wild. Their foods include insect larvae, algae, tiny invertebrates in the wild.

However, the Neon Tetras can eat brine shrimps, flakes, frozen food, algae wafers in the aquarium. These fish can even eat veggies from your kitchen. Unlike in the wild, you must take extra care of the Neon Tetras in captivity.

These fish must receive a balanced diet to keep them fresh and healthy. Make sure to feed the Neon Tetras with the adequate amount of diet that they require. Remember, your Neon Tetras will consume as much food as you provide happily.

But that does not mean that you should be careless. Provide just as much as it requires for a fish. Too much food will not only produce too much waste but will also harm the fish internally.

Fact #10: Super-Friendly And Peaceful Nature

This is one of the 15 fun and interesting facts about Neon Tetra and I guess the most important one. Well, I love Neon Tetras not only because of their beautiful coloration. Another reason is that these fish are super friendly.

You already know that the Neon Tetras love to live in schools. These fish are super friendly and love socializing with each other. Furthermore, the Neon Tetras are peaceful too. You will never see these fish fighting with each other.

If you see neon tetras being uncomfortable and aggressive, then understand that something is bothering your fish. Then, analyze what is bothering your fish and try to solve the matter. So, if you have kept the Neon Tetras as your pet, you will agree with me. These fish are super friendly and have a peaceful nature.

Fact #11: Fast Swimmers And Playful Beings

Trust me when I say this: You should not miss seeing the Neon Tetras swimming together in a group. But I am sure you have not missed that scene at all.

Well, if you have, make sure you do not miss the next one! The Neon Tetras are fast swimmers. You must see these fish swimming together in a group because that scene is worth watching.

When the group of Neon Tetras swims together, you will see the glorifying mixture of color inside your aquarium. Neon Tetras show their happiness and satisfaction by swimming around and around the tank too.

Seeing them being happy like that will make you happy in return. Keep one thing in mind. Even though the Neon Tetras are fast swimmers, these fish can’t fight with the high moving current.

Fact #12: Fin Nippers

I have seen most of the beginner fish keepers often curious about the same question. It is if the Neon Tetras are fin nippers or not.

Well, the answer is not entirely clear. Most of the Neon Tetras are fin nippers, and most of them spend their time chasing each other. You may notice the male chasing female, especially in the breeding season.

However, some Neon Tetras may not do anything like chasing. They will stick around with each other and keep doing their work of just swimming and eating. Even though the Neon Tetras are delicate, their fin nipping habit can sometimes create trouble too.

Some fish may even die because of the pain they feel. You should notice some Neon Tetras fin nipping other fishes. It occurs because of their uncomfortableness and not because of their aggressiveness. You should provide extra care to your Neon Tetra in such cases.

Fact #13: Egg Scatterers

Do you know that the breeding of the Neon Tetra pair is a bit challenging? It is because you need to keep the breeding pair in a separate tank.

You should also make sure the water is a bit warmer than the daily temperature to encourage fast breeding. The male usually chases the female when he is ready.

Can you distinguish the male and female Neon Tetra? Well, the male is slightly smaller and slimmer and has straight strips in the abdomen. The female has a broader body, and the stripes appear bent in the stomach.

Have you ever seen a female Neon Tetra lay the eggs? If you have, then you know that the Neon Tetras are egg scatterers.

When the mating occurs between the pair, it is best to leave them unseen for 24 hours. Later on, when you check the breeding tank, you will notice that the female has scattered the eggs all over.

If you did not know, a female lays hundreds of eggs at a time, which the male fertilizes right after. Unlike all other fish types, you should separate the breeding pair from the breeding tank after the mating process is over because these fish are not caring parents. It means that the Neon Tetras may eat the eggs.

Fact #14: Lifespan

The average lifespan of the Neon Tetra is 8 to 10 years. But, what if I tell you that I have seen the Neon Tetra that has even up to 15 years? You may find it hard to believe, wouldn’t you? But it is true.

It is possible, and it can happen if you take extra care of your Neon Tetra from the beginning. By beginning, I mean to say that you must buy a healthy Neon Tetra from a reputed, experienced and, famous fish hobbyist.

It will ensure that your fry neon Tetra is healthy. Then, you must feed your Neon Tetra with a balanced diet and provide a homely environment. A properly balanced diet, right tank conditions, and adequate water parameters are the factors that influence the longevity in the lifespan of Neon Tetras.

I think you are confused by reading this title. Am I right? Well, don’t worry! I am here to help you. Are you wondering why did I call the Neon Tetra inquiring investigator and interactor?

It will especially happen if any one of them finds something in the aquarium, and the others will come for investigation.

The next point is that these fish are interactors. It means that these fish can recognize their owner. Yes, you read it right. Your Neon Tetra will acknowledge you. In addition to that, these fish will come to the side of the tank where you are standing.
