How do I know if my guppy is sick?

When your guppy starts to show signs of lethargy or has a cloudy or bluish discoloration to the belly, you might have a sick guppy on your hands. If there is any bleeding from the mouth and gills, it most likely means that there is an infection in the body. There are many different types of infections that can occur with guppies, but one at a time.

What are the treatments for Guppy Fish Diseases?

Guppies are hardy fish that can survive in a wide range of different water conditions and environments. The Guppy is also one of the most popular aquarium fish, making it an often recommended choice for beginners. However, there are many diseases that affect the Guppy, including ich and others which can be very serious when left untreated.

One way to help prevent these diseases is to perform basic water changes for three hours every other day. Another way is to regularly give the Guppy food enriched with vitamins, minerals, and proteins to make sure they get the necessary nutrients they need to stay healthy and happy.

What should I do if my guppy gets sick?

The first thing is to determine the specific type of disease that your guppy has. There are several different diseases and their symptoms can vary depending on what they are. It is important that you look up the symptoms associated with the type of disease that your guppy has in order to find out if it needs medication or further treatment.

15 Common Guppy Disease

1) Fungus Couluminaris

This is a fungus that grows on the skin and scales of guppies. The fish will have white patches and die. Treatment includes giving them a bath, using an antifungal medication, and giving them a small dose of antibiotics.

2) Guppy Tuberculosis

Guppy tuberculosis is a type of fish bacterial infection that causes sores on the body and scales to fall off. The lesions are usually on the head. Symptoms of guppy tuberculosis include loss of appetite, weight loss, fin damage, respiratory distress, and vertebral displacement. Treatment for guppy tuberculosis includes antibiotics.

3) Velvet Guppy Disease

Velvet guppy disease is an infection that comes from a parasite called the Velvet Guppy parasite. It is typically found in fish with long, stringy filaments or mucus hanging from their gills. This can cause severe problems for the fish because it clogs up their gills and prevents them from breathing properly. The symptoms of velvet guppy disease include listlessness, extreme lethargy, and pale patches on the body. Velvet guppy disease can be treated by either chemical treatment or keeping your fish in a clean environment.

4) Viral Haemorrhagic Septicaemia (VHS)

In cell biology, there are three different types of cells. Normal cells, cancer cells, and virus-infected cells. Viral hemorrhagic Septicaemia is a disease that affects fish that causes significant mortality in the waters where it was discovered.

VHS is caused when a virus infects the blood of the fish and makes them hemorrhage from all orifices until they die. This viral disease kills up to 90% of infected fish in just one day after its discovery. However, there have been significant advancements in vaccines for this disease since its discovery.

5) Fish Pop-eye Disease

Fish pop-eye disease is a condition that can cause the eye to protrude from its socket. It is caused by a virus in the fish’s body where it multiplies rapidly and causes pressure on the eye, which forces it out of its natural position.

Fish with this condition often die quickly because of stress or bacterial infections. There are two types of medicines you can use to help treat this disease: anti-viral medications, like Amoxycillin, and antibiotics, like penicillin. The anti-viral medication works against the virus while antibiotics kill bacteria.

6) Guppy Gill Disease

Gill Disease is a disease that affects the gills rather than the body. It is caused by an infection called ich, which comes from fish that have been kept in overcrowded conditions. This leads to the destruction of the gill tissue. Treatment for Gill’s Disease includes antibiotics, cleaning the water, and moving the fish to more roomy quarters.

7) Dropsy

Dropsy is one of the most common diseases in guppies. Dropsy causes the guppy to grow so fast that it can’t move anymore. This disease has been seen in much other fish as well such as goldfish, Halfmoon, molly, and viviparous fish. The treatment for dropsy is to treat the symptoms of the disease until the guppy can heal itself.

8) Guppy Fin Rot / Tail Rot

Fin rot and tail rot are two different types of ich that affect all guppy fish. They are typically caused by poor water quality, injuries to the fish, or stress. Most guppy diseases will require a chemical bath, as well as regular doses of medication.

Sometimes, fin rot will happen when the fish is stressed and the fins are stuck together too much. The tail might also get red and infected. This can be treated with saltwater treatment or antibiotics.

9) Ick or Ich In Guppies

Ick or Ich is a common fungal infection in guppies that is caused by an overgrowth of the fungus, ichthyophthirius. Preventative treatment includes removing all infected fish, rinsing and drying the tank, following specific guidelines to ensure this doesn’t happen again, and using anti-fungal medication to treat the infection.

Ich is a parasite that causes red spots and white patches to appear on the skin of guppies. Ich will affect both males and females, though it may be more common in males due to the fact that they have no female guppies to clean them.

Guppy fish can also be infected with this parasite if they are in contact with an infected fish or driftwood. The best way to prevent ich is by filtering the tanks’ water, treating it properly with medication, and using quarantine tanks for new guppy arrivals.

10) Guppy Tuberculosis

Many guppies are infected with different types of bacteria, even if they seem to be healthy. When a guppy becomes infected, it can become very sick and die. To help this fish recover, it is important to give the fish medication that fights against the bacteria.

Tubers are the small, white, pea-shaped parasites of fish. They infest the body and can cause serious damage. If afflicted with this disease, your guppy needs to be given a bath in a salt solution twice a day. You should also change the water often and treat any water with your tubers in it with antiparasitic treatment.

11) Guppy (Tetrahymena)

Tetrahymena is a parasite that affects the digestive system of guppies. It causes heavyweight gain and death. Treatment for Tetrahymena is to use antibiotics to kill off the parasites in the digestive tract.

Tetrahymena is a protozoan that lives in the intestines of guppies. It can kill the fish, so it’s important to know how and when to administer treatment for this disease. Aquariums should be treated with an effective cleaner that eliminates the parasite and should be placed in quarantine for at least three weeks following treatment while they are still recovering from the treatment. Aquariums should also have their temperature checked periodically to make sure it doesn’t get too high, which can cause more problems with Tetrahymena.


Some of the diseases that are associated with guppy fish include bacterial ich, fungus, and whipworms. The symptoms of ich include a pale coloration on the body, cloudy eyes, and sunken spots on the skin. The causes of this disease are poor water quality and high temperatures. For treatment, a veterinarian can prescribe antibiotics or use saltwater dips to treat ich.
