What Is Dwarf Gourami Disease??

Dwarf gourami disease (DGD) is a bacterial infection that affects the gills and skin of dwarf gouramis, causing inflammation, lesions, and other symptoms. While it is not always fatal, it can be very harmful to fish and can lead to death in severe cases. There is no cure for DGD, but there are ways to treat it and prevent it from spreading. If you have a dwarf gourami, it is important to know what DGD looks like and how to deal with it if your fish becomes infected.

I had a very nice looking tank with what looked like two healthy dwarf gourami fish, but what I didn’t know was that one of them has what is known as the Dwarf Gourami Disease. It only infects the Dwarf Gourami Fish and there is no cure for it, but thankfully there are some things you can do to help combat this disease which I am going to go over below.

In this blog post, we’ll talk about dwarf gourami disease and what you need to watch out for if you’re hoping to land one of these beauties. Stay safe out there!

What is Dwarf Gourami Disease

Gouramis are a hardy family, but they may develop certain types of disease in the tanks. The most common diseases that affect gourami fish range from common freshwater ailments to one specific virus called dwarfg strain lattice gnat injection (DGSI). Knowing about these illnesses will help you identify and treat them before it’s too late!

The list of possible diseases you could find in your dwarf gourami fish is here:

1.     Fin Rot

Fin rot can be a serious issue for gourmi fish, especially if left untreated. The symptoms include decreasing appetite and whitish color that progresses towards death as the infection moves closer to its base on fins.

Fin rot is a bacterial infection that affects the fins of fish. It can be caused by poor water quality, stress, and other factors. Fin rot can be treated with antibiotics if caught early enough.


  • Red or black streaks along the fin
  • Fins may start to curl up or fall off

2.     Ichthys

Ich is a disease that can be caused by water protozoa. It causes white spots, pimples around the fins and even produces mucus on their skin which makes them look dirty in appearance or maybe even lethargic at times. If left untreated ich will result to frayed fins as well if not treated immediately upon noticing it – there’s no cure really but when treating with medication your gourami lives are saved!

When you get these white spots on your dwarf gourami, it means that they are filled with protozoan eggs. You can increase the water temperature until these sacks burst and then raise it to 90 degrees Fahrenheit (around 32 Celsius). Add in 1 teaspoon salt so that everything is properly disinfected before replacing decorations just as we did last time!


Dwarf Gourami Iridovirus is a virus that can be fatal to your dwarf gourami fish. The symptoms are loss of appetite, lethargy, swelling around the eyes and body, excessive mucus production and finally death. There is currently no known cure for this virus so it’s important to keep an eye on your fish and isolate any infected individuals.

4. New Tank Syndrome

If you’re new to the fish keeping hobby then it’s quite possible that your dwarf gourami has New Tank Syndrome. This is a disease caused by ammonia toxicity which can be very harmful for any type of ornamental fish. The symptoms are lethargy, loss of appetite and coloration changes including darkening or lightening in color.

These are the most common diseases that you can find in a dwarf gourami fish so it’s important to take note of what they look like and how to deal with them as early as possible!

How to Prevent Dwarf Gourami Disease

The best way to prevent dwarf gourami disease is by keeping your tank clean and free of waste. This means cleaning your tanks at least once a week and removing any dead fish immediately. You should also test the water’s pH level, ammonia, nitrite, and temperature.

If your fish are showing symptoms of dwarf gourami disease or you have recently lost a tankmate to the illness, it’s best to perform daily water changes until they start looking healthier again.

You should also feed your fish at least once a day so that food doesn’t build up in the tank overnight and potentially cause the disease to spread further.
