Can you keep two male Ember Tetra together? Yes, but it takes work. This article will explore the dos and don’ts of keeping a tank with only two males in order to reduce any possible fighting and stress.

Some people say that if you’re not careful, the males will fight until one dies or both die. Others claim that it is possible for two males to live in harmony as long as there are plenty of hiding spots and plants for each of them to stake out their territory in peace. This article aims to provide some answers about keeping these beautiful fish alive in your home aquarium!

So, Can You Keep Two Male Ember Tetra Together?

Male Ember Tetras are known to be aggressive, and they will often fight to the death. They tend to establish a pecking order, where one is dominant over the other. The dominant fish may also chase away any other males in the tank that try to enter his territory.

One way around this problem would be to choose a big tank so there is plenty of space for each fish. You should also make sure your tetras are similar in size before introducing them into the same tank; otherwise, you might end up with one being chased around all day by another who’s much larger than him!

Pecking Order

The Ember tetra tends to love living under hierarchy. If there are more than one Ember tetra in the tank, you will see them chasing each other and establishing their own dominance.

Searching For Females

If all of your males turn into females (which is possible), they might start searching for female partners to reproduce with. You can prevent this by keeping only two male Ember tetras together.


If you have a bigger Ember tetra in the tank, it can become dominant. You will need to create more hiding spaces for smaller ones so they don’t get bullied too much by larger fish.

How Can You Keep Only Two Male Ember Tetra Together?

In order to keep two male Ember tetras together, you will need a large aquarium of at least 30 gallons or even more. If your tank is not big enough and there are other inhabitants in it (other than Ember tetras), then this might cause problems with dominance and pecking order issues that we mentioned earlier in this post.

Choose A Big Tank

You also want to make sure that all of your ember tetras stay healthy because sick fish tend to be more aggressive and dominant than healthy ones.

Create Hiding Spots

Creating hiding spots for your Ember tetras can help reduce or prevent bullying, stress, and other issues that might happen between fish of the same species.

Feed Your Ember Tetras Well

You also want to make sure you feed them well as this will ensure they stay healthier longer. If ember tetra is not feeling their best due to hunger, it’s going to become stressed out easily which can cause problems with dominance in a small tank especially if there are only two males living together under such conditions.

Observe Behavior Of Your Ember Tetra Everyday

Make sure you observe how your male Ember tetra behaves every day so that you know what kind of changes to look out for. If you notice any changes, make sure to take action immediately before it is too late for your Ember tetra fish.

Can You Keep More Than Two Male Ember Tetra Together?

No, but one might be ok depending on the tank size and if they are well fed or not because hunger can cause stress which can result in dominance issues between males of the same species (even though they would never usually fight).

How Can You Create A Harmonious Ember Tetra Tank?

Creating a harmonious ember tetra community tank takes time as all fish need acclimatization periods so that their immune systems adapt to each other’s presence better instead of “fighting” against them constantly – this will help reduce stress and conflicts.

Best Water Parameters For Ember Tetra

If you want to keep ember tetras, take a look at the best water parameters for them: Temperature between 76-82 degrees Fahrenheit (24 – 28 Celsius) pH level of around neutral or slightly acidic. Soft to moderately hard with an ideal GH of about 12 °dGH. The KH should be low but not nonexistent.

Maintain Tank Size

The minimum tank size is 30 gallons because they really enjoy being in bigger aquariums and it’s also better if there are more hiding spots available and don’t forget that all fish need time to get used to each other which means acclimatization periods without any problems occurring.

Reduce Stress

You should also reduce stress as much as possible by not overfeeding them and choosing fish that are of similar size instead of putting predators with prey.

Good Tank Mates

It’s also important to choose tank mates that are not too aggressive or fin nippers as Ember tetra can become stressed if they have constant fights with other fish. They should be the only fish in your aquarium but you might consider adding a plecostomus because these catfish tend to eat any leftovers which will help prevent overfeeding and reduce the possibility of parasites.


Does Male Ember Tetra Get Lonely?

No, they don’t get lonely because ember tetras are schooling fish which means that they prefer to stay in schools even though males of the same species might fight from time to time.

Why Are My Male Ember Tetra Dying?

If your male ember tetras start dying one after another, it’s possible you have a disease going on or a parasite infestation in your tank. This can be prevented by making sure all water parameters are well within their optimal ranges, doing regular water changes, and not overcrowding your aquarium with too many fish at once (in order to reduce stress).


In conclusion, this is what you need to know about keeping two male Ember tetra together. Make sure you choose the right tank size, create hiding spots for smaller fish, feed them well, observe their behavior every day if possible. You should lastly make sure that you optimize water parameters to reduce stress as much as possible.
