Goldfish Parasitic Diseases
One of the most common goldfish diseases is parasites. Parasites are tiny organisms that live off of other creatures, and they can cause a variety of problems for goldfish. Some common symptoms of parasites include lethargy, loss of appetite, increased mucus production, and white spots on the body. If you notice any of these symptoms in your goldfish, it’s important to take them to the vet for a diagnosis and treatment.
There are a number of different parasites that can infect goldfish, including flukes, velvet disease, white spot (ich), and chilodonella. Each of these parasites can cause different symptoms, so it’s important to be aware of the signs and symptoms of each one.
White Spot (Ich)
One of the most common goldfish parasitic diseases is a white spot, also known as ich. Ich is a small parasite that attaches itself to the body of the fish and causes White spots to form on the skin. Ich can also cause a variety of other symptoms, including lethargy, loss of appetite, and increased mucus production. If you notice any of these symptoms in your goldfish, it’s important to take them to the vet for a diagnosis and treatment.
Symptoms:
- Small, pure white dots that are clearly delineated.
- Someone appears to have sprayed salt all over the fish’s body.
- Fins may cluster due to apatite loss.
- Their bodies may be scratched by harsh items, decorations, or stones.
Treatment:
To address this, you’ll need to replace 75% of the water and apply water treatments like Aquarisol + 1 tablespoon salt per 10 gallons right away.
For a few days, raise the water temperature to 20°C – 23°C (68 °F – 74°F).
Do a 50 percent water change every day, and once the fish is cured, treat the entire tank.

Flukes
Because worms form in the fish’s gills, this condition is frequently referred to as gill flukes. The fish will scrape themselves on the rocks and rough surfaces as a result of this. During breathing, the fish’s gill plates will be closed or not working at all. The fish will suffocate as a result of this.
Symptoms
- lethargy,
- loss of appetite,
- increased mucus production,
- and white spots on the body.
If you notice any of these symptoms in your goldfish, it’s important to take them to the vet for a diagnosis and treatment.
Treatment
Flukes can be treated with a variety of different medications, including fluke tabs, praziquantel, and metronidazole. Formalin works best for goldfish flukes.
It’s important to follow the directions on the medication label carefully, as over-medicating can be harmful to goldfish.
Velvet Disease
During the infection stage, the parasites connect to the goldfish host and feed on it. The condition first resembles the tiny white spots caused by ich. However, it eventually fades to a fine dusty gray or yellow tint. In an attempt to battle the sickness, the sick goldfish will create an excessive amount of mucus, giving it a velvety texture.
Symptoms:
- Gills that move quickly
- Scratching and/or flashing are two different types of scratching.
- Fins are clamped together.
- The body is covered in a yellow-grayish coating.
- Mucus production that is excessive
- Eyes that are cloudy or protrude
- Ulcers and skin thinning
Treatment
You can treat velvet disease in goldfish by using a variety of different medications, including copper sulfate, formalin, and hydrated lime.
It’s important to follow the directions on the medication label carefully, as over-medicating can be harmful to goldfish.
Chilodonella
Chilodonella is another type of parasite that can infect goldfish. It’s a protozoan infection that is typically found in freshwater environments. Chilodonella parasites can remain latent for long periods of time, but when a goldfish’s immune system is weakened due to injury or stress, an outbreak can emerge.
Poor water quality and poor goldfish care are the most common causes of goldfish stress. A goldfish that has not been adequately quarantined before being placed in a goldfish tank or pond can readily infect a colony of goldfish.
Symptoms:
- Fins tangled
- Isolation
- Web-like hemorrhages on the skin due to excessive slime production
- Gasping for air at the surface
Treatment
Chilodonella can be treated with a variety of different medications, including formalin, malachite green, and Potassium permanganate.
It’s important to follow the directions on the medication label carefully, as over-medicating can be harmful to goldfish.
Lice & Worms
There are two main types of worms that can infect goldfish: flatworms and roundworms. Flatworms are typically found in saltwater environments, while roundworms are more common in freshwater environments. Both types of worms can cause a number of different problems for goldfish, including weight loss and anemia.
Symptoms:
- Weight loss
- Anemia
Treatment
You can treat worms with a variety of different medications, including praziquantel, levamisole, and fenbendazole.
It’s important to follow the directions on the medication label carefully, as over-medicating can be harmful to goldfish.
Fish Pox
Fish pox is a viral infection/ goldfish diseases that can affect both freshwater and saltwater fish. The virus is typically spread through contact with infected fish or contaminated water. It can also be spread through contact with infected humans or animals. Symptoms of fish pox include lethargy, loss of appetite, and white spots on the body. In severe cases, fish pox can lead to death.
There is no cure for fish pox, but there are a few things that can be done to ease the symptoms and help the fish recover. These include Quarantine, euthanasia, and supportive care.
Symptoms:
- Lethargy
- Loss of appetite
- White spots on the body
In severe cases, death.
Treatment:
There is no cure for fish pox, but there are a few things that can be done to ease the symptoms and help the fish recover. These include quarantine, euthanasia, and supportive care.
Quarantine is often the best course of action when dealing with an infected fish. This involves isolating the sick fish from healthy ones to prevent the spread of disease.
Euthanasia may be necessary if the fish is suffering and there is no hope of recovery. This should be done in a humane way, such as using a clove of garlic or an overdose of anesthesia.
Supportive care can help to ease the symptoms of fish pox and make the fish more comfortable. This includes adding salt to the water, increasing aeration, and providing plenty of hiding places.
Goldfish Bacterial Infection Diseases
Bacterial infections are one of the most common health problems in goldfish. They can be caused by a variety of different bacteria, including Pseudomonas, Aeromonas, and Mycobacterium. Bacterial infections can cause a number of different symptoms in goldfish, including lethargy, loss of appetite, and white spots on the body. In severe cases, bacterial infections can lead to death.
Pop Eye
Popeye is a condition that results in the bulging of one or both eyes. It can be caused by a number of different things, including infection, injury, or disease. In most cases, popeye is not serious and will resolve on its own within a few weeks. However, in some cases, it can lead to blindness or even death.
Symptoms:
- Bulging of one or both eyes
- In some cases, blindness
Treatment:
Most cases of the popeye will resolve on their own within a few weeks. However, if the condition is severe, it may require treatment. Treatment options include antibiotics, surgery, and steroids.
Dropsy
A goldfish’s digestive system is affected by Dropsy. If you don’t take care of it right away, the goldfish’s health could become a significant problem.
A bacterial infection of your internal fish organs is the most common cause of dropsy. However, as I have already indicated, the quality of water has a direct impact on the development of diseases. Overcrowding of decorative items in the tank might stress the fish, resulting in this sickness.
You will be able to view excess bodily fluid that has built up inside the fish in order to diagnose this condition. The eyes and scales are enlarged to a greater extent than usual. There will be a decrease in appetite as well as the fish becoming bloated.
Symptoms:
- You’ll be able to see the surplus bodily fluid that accumulates inside the fish.
- Large eyes and scales to an abnormal degree.
- I’m going to stop eating.
- It’s possible that the fish will appear swollen.
Treatment:
Most cases of dropsy will resolve on their own within a few weeks. However, if the condition is severe, it may require treatment. Treatment options include antibiotics and fluids.

White Poop
One of the most prevalent ailments that a Gold Fish can contract is white poop disease. The fish excretes white stringy, sticky excrement, which is known as White Stringy Feces Disease. The fish may have a swelled belly or stop eating when they have white feces sickness. One of the primary causes of this condition is Hexamita, an intracellular parasite.
Additionally, feeding frozen and live meals to goldfishes can raise the chances of them being ill. The tank’s low water quality could also be a contributing issue. Worms might proliferate inside the fish as a result of the high protein diet.
Symptoms:
- A decrease in appetite
- The fish starts pooping a white sticky substance.
Treatment:
For treatment, use Aqua Product’s CLEAR medication or OCEANFREE WHITE POOP. Raise the water temperature over 20-23 degrees Celsius.
Allow your fish to go three days without eating. On the third day, remove at least 30% of the water. Rep the medication till the fish appears to be in good health. Feed a low-protein diet to the fish.
