Why Is My Dwarf Gourami Losing Its Color? 3 Reasons

Have you ever noticed that your dwarf gourami is losing its color? This can be a sign that something is wrong with your fish, and it’s important to determine the cause as soon as possible.

In this blog post, we’ll discuss some of the most common causes of color loss in dwarf gouramis and how to address them. Keep reading to learn more!

Why Is My Dwarf Gourami Losing Its Color?

It could be due to too many reasons. Some of them listed below:

  • Color Loss Due to Stress
  • Color Loss Due to Physical Injury
  • Color Loss Due to Disease

Color Loss Due to Stress

Dwarf gouramis are a hardy species that can tolerate a wide range of water conditions, but no fish is invincible. Even peaceful dwarf gouramis can become aggressive when they’re stressed out by something in their environment, and this stress often causes them to lose their vibrant coloration.

In this case, the cause of stress is usually something in the dwarf gourami’s environment; possible suspects include too much or too little light, an inappropriate tank mate (for example, a very large cichlid with your tiny dwarf), and water that’s unusually warm or cold.

There are also some diseases, like velvet, which can cause fish to lose their coloration. We’ll talk more about these causes of color loss and how to treat them in a moment, but first we’re going to take a look at the next most common reason for this issue:

Color Loss Due to Physical Injury

Sometimes your dwarf gourami can lose its color as a result of physical damage. This can be due to jumping out of the tank, being attacked by another fish, or even just rubbing up against something in the tank (like a heater). It’s important to take your gourami to the vet if you suspect that this is what’s causing its color loss; otherwise, it won’t get better and may continue to get worse.

Color Loss Due to Disease

As we mentioned earlier, there are some diseases that can cause fish to lose their color or appear “washed out.” These include bacterial infections, parasitic infestations, and velvet. If you suspect your dwarf gourami has an infection of this type, take it to the vet immediately so you can get the proper medication.

Preventing Disease in Dwarf Gouramis

The best way to prevent disease is by making sure your dwarf gourami has a clean environment. That means performing weekly water changes, cleaning the tank with warm water and aquarium salt (never soap or other cleaners), and always providing fresh food like brine shrimp.

If you notice your fish beginning to lose its color, take it to the vet as soon as possible. The earlier you catch a disease like this, the easier and less expensive it will be to treat!

Identifying Different Types of Fish Diseases

There are several diseases that can cause dwarf gouramis to lose their color. Some have already been mentioned: velvet and bacterial infections tend to cause fish to lose their color, while diseases like ich and fin rot can also make your fish look “washed out.”

However, there are other types of diseases that can affect dwarf gouramis as well. Let’s take a look at some of the most common ones now:

Bacterial Infections

Dwarf gouramis can often develop bacterial infections when they’re stressed out by poor water quality or a dirty environment. Many fish diseases are caused by bacteria, but fortunately, your dwarf gourami can be protected from these simply by keeping its tank clean.


Dwarf gouramis sometimes contract velvet, which is actually a parasite. The good news is that this disease can be treated with the right medication; the bad news is that it’s potentially fatal, so you’ll need to take prompt action if your fish begins showing symptoms of it.


“Ich” sounds like an abbreviation for something else – maybe “ick,” as in “ick, not another fish disease!” Well, it stands for ichthyophthirius, a one-celled parasite that can invade your dwarf gourami and cause all kinds of problems.

It’s important to treat this type of infection quickly to prevent the parasite from eating away at your fish’s body.

Fin Rot

If your dwarf gourami’s fins begin to look frayed and ragged, it may have contracted fin rot. This, too, is a type of infection caused by bacteria. Fortunately, though it can be fatal if left untreated, this disease can usually be treated without too many problems.

So what’s going on with your dwarf gourami? Is its color loss due to a physical injury, a disease, or just poor water quality? The way you find out for sure is by taking it to the vet – if it’s an infection of some type, the doctor will be able to treat it.

Don’t delay!

Dwarf Gouramis can get very sick, and the earlier you treat a disease, the better. If your fish does have an infection, take it to the vet right away!
