Neon Tetras: CHARACTERISTICS

Also called Blue Neon, the Neon Tetra (Paracheirodon innesi) is an oviparous freshwater fish, of small size, which belongs to the family of Characidae. Its life expectancy is around 6 years. They originate from South America, and more precisely, from Peru, Colombia, and Brazil. It is now very present in most aquariums of individuals around the world.

The blue Neon is not much more prominent in length. It can be identified by the long, bright blue side stripe (more curved in the female), which follows all along its back and its half-red belly. Attractive with its electric colors, it is very lively. Very friendly with his fellows, he lives in a school. Blue Neons are relatively indifferent to other species of fish.

What Should Be the Ideal Condition of Your Aquarium to Ensure The Growth?

The environment has a significant impact on growth. The Neon Tetra needs freshwater whose temperature is constant, and between 18 and 22 ° C in its natural environment. But in the aquarium, it can be from 18 to 28 ° C, knowing that the ideal range in these conditions d existence is water between 22 and 25 ° C. It is essential to keep it alive to ensure that the water temperature does not fluctuate.

The advice is equally valid concerning the hardness of the water or GH, which must be between 1 and 12. This mineral range is defined according to the quantity of magnesium and calcium ions. For the aquarium water to keep blue Neon lights for a long time, it must also have a pH (Hydrogen potential) between 5 and 7, which can at most go up to 7.5.

These small fish like to take advantage of shaded places and a vegetated environment. On the other hand, they prefer medium-deep aquariums.

 

How to Make Your Neon Tetra Grow Sufficiently?

  • It All Starts with A Good Diet

And it is that, as the saying goes, “from what you eat, you breed.” In the variety is the secret to have healthier fish!

Yes, just as you hear it. Why give only one type of food when we have at our disposal an incredibly wide variety to offer our fish? Special meals for omnivores, freeze-dried food for many kinds of frozen, etc. A healthier diet improves the growth of Tetra fish.

Always have a base diet, the one you use most of the time (at least 1 or 2 times a day). Another advice is that you have at least 3 different types of food available always to give to your fish.

And now the right thing begins: we have many types of food to drive our fish crazy. What do I recommend for you? Choose two from the following list and alternates with the base diet:

  • Flake food of different flavor and composition.
  • Frozen food.
  • Frozen porridge (just great, but it contaminates the water, little eye, and the parrot with the changes of water).
  • Food that decomposes very slowly and that the fish can peck at (such as bottom tablets, but there are also versions for all aquarium fish).

 

  • OBJECTIVE: To Have Nitrates at 0

If you have nitrates in more than 20 parts per million, I am very sorry, but you will always have trouble ensuring the growth of your fish. Well, because nitrates are nothing more than water pollution due to the degradation of organic compounds. It follows the nitrogen cycle. The more you accumulate in your aquarium, the less your fish will grow, and the weaker they will be. The fewer nitrates, the healthier fish.

 

  • Phenolic Compounds

When you change the water in your aquarium and pour it into a white bucket, does the water turn yellow? If the answer is yes, it is almost sure that you have tannins in your aquarium. But my neck is that you also have a lot of phenolic compounds.

How many more are there, the worse your fish will be! Simply because they inhibit the growth and proper development of fish when there is a high concentration of phenolic compounds in the water. The solution is simple: increase the frequency of water changes—the ultimate goal: to have healthier fish every day.

 

  • Avoid Overcrowding

Most of our aquariums are overcrowded and have too much biological charge inside. We have too many live animals that generate too much organic matter. They must subsequently decompose, worsening the quality of the water.

Also, overpopulation automatically creates more interactions between animals, and this is not always a good thing. Competition to get food increases. Bottom Line: Delicate or shy fish have trouble getting food. Thus they lack growth.

Water quality decreases if we do not have a continuous water change system. The stress generated by overpopulation makes fish more undergrowth.

 

  • Do Not Combine Incompatible Species

I would dare to say that almost every day we have to play bad cop and say: don’t take those fish with you, they’ll mess with what you have. And we do it because that’s what we are for, to advise you and make your aquarium go better. Putting scalars with Neons is usually not a good idea (unless you want to run out of Neons, hey). The same as trying to raise guppies in an aquarium full of Tetras. Or combine Oryzias woworae (a beautiful and quite calm fish, by the way) with cherry barbels, which are like a formula one at mealtime.

Because dominant fisher will snatch food, space, and reducing the growth of Neons.

 

  • Observe Your Fish

It’s a no-brainer, isn’t it? But many times, we overlook sitting down and calmly reviewing the behavior of our fish. The most important advice I can give you when you do this is not to stick to the aquarium. Observe your fish from one or two meters away. You will see how the behavior of animals is different. And yet the fish are not stupid, and as soon as they see us move in front of the aquarium, even if we are at a distance, they change their behavior.

Once you have observed your fish from afar, it is time to get closer to the aquarium and take a careful look. If it has a problem with its fins or the rest of its body, we can remedy it (separate aggressive companions, transfer it to another aquarium or separate it for a while to regain weight).

 

  • Ideal Feeding

In seawater, Ocean Nutrition’s grains flakes are simply fabulous. But in an aquarium, it’s a little confusing.

And now comes the fundamental issue, when do we choose flake, and when do we choose the grain? Well, for this question, we also have it clear: if your fish eat the grain, go ahead with it. The scale is less nutritious when it comes into contact with water. Because it loses vitamins in a short time as it breaks down in the water. The grain, on the other hand, takes longer to break down and has much more content.

And we all know, fewer nutrients, reduced growth.

 

I hope that with all these tips and tricks, you will have healthier, lustrous, and showy fish. And remember that if there is any problem regarding growth, get help from experts.
