In this blog post, we’ll take a closer look at the care and keeping of neon tetras.

So, without further ado, let’s get started.

Are Neon Tetras Hardy?

Yes, once they’re used to the tank environment, neon tetras are hardy.

They may, nevertheless, appear a bit odd-colored and delicate for the first few days.

Even though neon tetras are robust, certain water temperature, pH levels, and hardness requirements must be respected in order for them to thrive.

What Makes Neon Tetras Hardy?

1. They Can Tolerate Wide Range Of Temperatures

Neon tetras can tolerate a wide range of temperatures, making them one of the hardiest fish you can buy.

This means that you don’t have to worry about them dying if the temperature in your tank fluctuates.

2.  They’re Peaceful fish

Neon tetras are usually quite peaceful fish and will not bother other fish in the tank.

This makes them a good choice for people who are just starting out with keeping fish or those who don’t have a lot of experience.

3. They’re Easy to Take Care Of

Another reason why neon tetras are hardy is that they’re easy to take care of.

All you have to do is make sure the water in their tank is clean and that they have enough food to eat.

You also need to monitor the pH levels and water hardness in their tank, but this isn’t difficult to do.

Factors That Affect The Health Of Neon Tetras

While there are many reasons why neon tetras are hardy, there are also a few things that can affect their health.

Some of these factors include water temperature, pH levels, and water hardness.

1. Water Temperature

If the water temperature in your tank is too high or too low, it can have a negative effect on the health of your neon tetras.

This is why it’s important to make sure the temperature in your tank stays within the recommended range.

2. pH Levels

The pH levels in your tank can also have an impact on the health of your neon tetras.

If the pH levels are not suitable for them, it can cause the fish to become sick or even die.

It’s important to monitor the pH levels in your tank and make sure they stay within the recommended range.

3. Stress

If the fish are stressed, they may become sick or die.

One way to reduce stress is to make sure the tank is well-maintained and that there are enough food and hiding places for the fish.

4. Poor Genetics

This is something that you can’t control, but it’s important to be aware of it.

For this, you must obtain neon tetras from trustworthy pet shops or breeders who provide excellent care for their fish.

5. Poor Water Quality

If the water quality in your tank is poor, it can also have a negative effect on the health of your fish. 

This is why it’s important to keep the tank clean and to change the water regularly.

6. Sudden Water Changes

Sudden water changes can also be harmful to fish and should be avoided.

Partial water changes are necessary, but you should avoid doing so too quickly since it may harm the neon tetras.

Also, rapid fluctuations in water temperatures can induce trauma in neon tetras. They become more prone to disease as a result of this.

7. Overfeeding

While overfeeding is not a direct cause of death in neon tetras, it can have a negative effect on their health.

This is because it can lead to poor water quality and an increase in algae growth.

It’s important to only feed the fish enough food so that they can consume it all within a few minutes.

8. Overcrowding

Although neon tetras are tiny fish, they are energetic swimmers that enjoy swimming about in their tank.

If the tank is full, there will be space issues and the fish will become suffocated and anxious.

In addition, overcrowding depletes the water’s oxygen levels.

The more the number of fish, the more oxygen is needed.

9. Wrong Tankmates

If you put the wrong tankmates with your neon tetras, it can lead to problems.

Some fish may eat the neon tetras or harass them, which can lead to stress and illness.

It’s important to choose fish that are compatible with neon tetras.

10. Loneliness

While this may not be a health issue, it can still have a negative effect on the neon tetras.

Neon tetra are schooling fish, and if they are left alone in their tank for long periods of time, they may become stressed and lonely.

It’s best to have at five three neon tetras in your tank so that they don’t feel lonely.

11. High Water Currents

If the water current in your tank is too high, it can also be harmful to the fish.

This is because they may get swept away or sucked into the filter.

It’s important to make sure that the water current is not too strong for the neon tetras.

12. Poor Habitat

If their habitat is not suitable, neon tetras may become stressed and sick.

Their habitat should include a well-maintained tank with plenty of plants and hiding places.

The water should be clean and have the correct pH levels and water hardness.

13. Fish Diseases

One of the most common reasons why neon tetras die is from fish diseases.

There are many different types of fish diseases, and some can be fatal.

It’s important to keep an eye on the fish for any signs of illness and to treat them as soon as possible.
