Why Does My Betta Have Swollen Gills?

Betta fish, also known as Siamese fighting fish, are a popular species of freshwater aquarium fish. They are known for their bright colors and long fins, and are relatively easy to care for.

However, bettas are also prone to a number of health problems, one of which is swollen gills.

Swollen gills in bettas are usually caused by poor water quality, and can be a sign of several different diseases. In some cases, swollen gills can be a symptom of something as simple as a bacterial infection, while in other cases it may be a sign of a more serious disease such as gill parasites.

If you notice that your betta’s gills are swollen, it is important to take action immediately in order to ensure the health of your fish. The first step is to test the water quality in your aquarium and make sure that it meets the standards for bettas.

If the water quality is good, you may need to treat your fish for a bacterial infection or other disease.

How do you treat inflamed gills?

If you are treating an inflamed gill, you will want to remove any debris, excess fluid, and mud that is on the fish. If the fish is in too much pain, you may also want to euthanize it.

You can treat an inflamed gill with antibiotics, a anti-inflammatory medication, or a saltwater solution.

What causes fish gills to swell?

Fish gills swell when there is an increase in water flow through the gills. This can be caused by a number of factors, including but not limited to:
– Swimming in high water currents
– Swimming in cold water
– Eating a lot of food
– Fighting with another fish

Why are my betta fish’s gills puffed out?

Some betta fish have enlarged gills that may look puffed out. Enlarged gills may be caused by a variety of reasons, including:

1. Overfeeding – Overfeeding your betta fish may cause them to excessively consume water, which can lead to their gills becoming enlarged.

2. Water quality – If your betta fish’s water is of poor quality, it may contain high levels of chlorine or other chemicals that can damage their gills.

3. Disease – If your betta fish is suffering from a disease, their gills may enlarge as a result.

If you are unsure as to why your betta fish’s gills are enlarged, it is best to take them to a qualified fish care professional for a diagnosis.

How do you treat gill hyperplasia?

Gill hyperplasia is a problem that affects the gills of fish. It is a condition where the gills grow too large.

This can prevent the fish from breathing properly, and can eventually kill the fish. Treatment for gill hyperplasia depends on the severity of the condition.

In most cases, the fish will need to be treated with antibiotics to prevent it from dying.


One possible reason for your betta’s swollen gills could be a reaction to the water they are in. If the water is too cold or has high levels of ammonia, this could cause your fish to experience gill damage.
