What Is Velvet Disease?

Velvet Disease is a parasitic infection that affects freshwater fish, including Betta fish. The name comes from the velvety appearance of the infected fish, which results from the parasite’s tiny, velvety cysts on the fish’s skin. The disease is highly contagious and can spread rapidly through an aquarium, leading to devastating consequences if left untreated.

What Parasite Causes Betta Velvet?

Betta Velvet is caused by a parasitic protozoan called Piscinoodinium pillulare. This parasite belongs to the dinoflagellate family, and it infects the gills, skin, and fins of freshwater fish, including Betta fish.

The parasite has a complex life cycle that involves several stages, including the Tomont, Juvenile, and Adolescent stages. During the Juvenile stage, the parasite attaches itself to the fish’s skin, causing significant damage to the fish’s tissues and weakening its immune system.

Tomont

The first stage of the Velvet Disease parasite is the Tomont stage. At this stage, the parasite is still enclosed in a cyst. That cyst protects it from external factors such as changes in temperature, pH, and water quality.

The cyst is also resistant to most disinfectants, making it challenging to eradicate the parasite from an aquarium once it has established itself. During this stage, the parasite reproduces asexually by dividing itself into two or more cells, creating multiple cysts that can hatch and infect new hosts.

Juvenile

Once the cysts hatch, the parasite enters the Juvenile stage, which is the second stage of its life cycle. At this stage, the parasite becomes a free-swimming organism and seeks out a host.

The parasite attaches itself to the host’s skin and feeds on its mucus, blood, and skin cells, causing significant damage to the fish’s tissues. The Juvenile stage is particularly dangerous because the parasite can reproduce sexually at this stage, which increases the rate of infection and makes it difficult to control.

Adolescent

The Adolescent stage is the final stage of the Velvet Disease parasite’s life cycle. At this stage, the parasite matures and reproduces sexually, creating more cysts that can infect new hosts. The Adolescent stage is also the most visible stage.

In this stage, parasite is no longer microscopic and you can see them with the naked eye. Infected fish will often display visible symptoms such as a velvety appearance on their skin, lethargy, loss of appetite, and difficulty breathing. If left untreated, the disease can lead to death in a matter of days.

Velvet Disease Causes

Velvet Disease is a serious and potentially fatal ailment that can affect Betta fish. It is important to understand the various causes of Velvet Disease to effectively prevent and treat it in your aquarium.

Parasites

The most common cause of Velvet Disease is a parasitic protozoan called Piscinoodinium pillulare. This parasite is highly contagious and can quickly spread throughout an aquarium, infecting multiple fish.

Once a fish is infected, the parasite attaches itself to the fish’s skin, causing tiny velvety cysts. If left untreated, the cysts can cause significant damage to the fish’s tissues and eventually lead to death.

Poor Water Quality

Poor water quality is another major cause of Velvet Disease in Betta fish. When the water in the aquarium is dirty, contaminated, or poorly oxygenated, it can create an environment that is conducive to the growth of parasites and other harmful organisms. The stress of living in poor water conditions can also weaken a fish’s immune system, making it more susceptible to infections.

Stress

Stress is a significant contributing factor to the development of Velvet Disease in Betta fish. Stressful conditions such as overcrowding, poor water quality, and sudden changes in temperature or pH can cause a fish’s immune system to weaken, making it more vulnerable to infections. Fish that are stressed are also more likely to display symptoms of Velvet Disease, such as lethargy and loss of appetite.

Poor Nutrition

A poor diet can also contribute to the development of Velvet Disease in Betta fish. Fish that are not getting the proper nutrients they need to maintain a healthy immune system are more susceptible to infections. It is important to provide your Betta fish with a balanced diet that includes high-quality protein and vitamins to ensure they remain healthy and disease-free.

Symptoms of velvat disease

Incessant Scratching

One of the most common symptoms of Velvet Disease in Betta fish is incessant scratching. Affected fish will rub against objects in the aquarium in an attempt to alleviate the irritation caused by the parasite. If you notice your Betta fish scratching frequently or rubbing against objects in the aquarium, it may be a sign of Velvet Disease.

Cloudy Eyes

Another symptom of Velvet Disease in Betta fish is cloudy eyes. The parasite can cause inflammation of the eye, resulting in a cloudy or hazy appearance. If you notice your Betta fish’s eyes are cloudy or appear hazy, it is important to seek treatment immediately.

Peeling or Velvet-Like Growths

The parasite that causes Velvet Disease in Betta fish can also cause peeling or velvet-like growths on the skin. These growths may be white, gray, or yellow in color and may be visible on the fins, body, or head of the fish. If you notice any unusual growths on your Betta fish, it may be a sign of Velvet Disease.

Redness or Inflammation of the Skin

Redness or inflammation of the skin is another common symptom of Velvet Disease in Betta fish. The parasite can cause irritation and inflammation of the skin, resulting in redness or discoloration. If you notice your Betta fish’s skin appears red or inflamed, it may be a sign of Velvet Disease.

Clamped Fins

Affected Betta fish may also display clamped fins, a symptom commonly associated with stress. This can occur due to the irritation and discomfort caused by the parasite. If you notice your Betta fish’s fins are clamped or appear to be held tightly against their body, it may be a sign of Velvet Disease.

Fast Breathing or Gasping

Fast breathing or gasping is another symptom of Velvet Disease in Betta fish. The parasite can cause respiratory distress, making it difficult for the fish to breathe. If you notice your Betta fish is breathing rapidly or appears to be gasping for air, it may be a sign of Velvet Disease.

Loss of Appetite

Loss of appetite is another symptom commonly associated with Velvet Disease in Betta fish. The parasite can cause significant discomfort and may make it difficult for the fish to eat. If you notice your Betta fish is not eating or appears to have a decreased appetite, it may be a sign of Velvet Disease.

Fading or Darkening Colors

Finally, affected Betta fish may display a change in color. This can be due to the stress and discomfort caused by the parasite or a result of the infection itself. If you notice your Betta fish’s colors are fading or darkening, it may be a sign of Velvet Disease.

Velvet Disease Treatment 

Betta velvet disease, also known as velvet disease or gold dust disease, is a parasitic infection caused by Piscinoodinium pillulare. This microscopic parasite can affect both freshwater and saltwater fish, including Betta fish. If left untreated, velvet disease can quickly become fatal for your Betta.

Fortunately, with prompt treatment, velvet disease can be cured. In this article, we’ll discuss the steps you can take to treat velvet disease in Betta fish.

Isolate Your Betta

The first step in treating velvet disease is to isolate your Betta from any other fish in the tank. Velvet disease is highly contagious and can quickly spread to other fish in the tank. It’s important to move your Betta to a quarantine tank to prevent the spread of the disease.

Turn up the Temperature

The next step is to increase the temperature in the quarantine tank. Velvet disease thrives in cooler temperatures, so raising the temperature to around 86°F (30°C) can help to kill off the parasite. However, make sure not to raise the temperature too quickly, as this can cause stress for your Betta.

Keep the Tank in the Dark

Velvet disease is photosensitive, which means that light can stimulate the growth of the parasite. Keeping the quarantine tank in the dark can help to slow down the growth of the parasite and give your Betta a better chance of recovery.

Check the Water Parameters

It’s important to check the water parameters in the quarantine tank regularly. Velvet disease can weaken your Betta’s immune system, making them more susceptible to other illnesses. Make sure to keep the water clean and free of toxins by doing frequent water changes.
