If you’ve ever seen a fish swimming erratically, darting around the tank and slamming into the glass, you may have wondered if fish can have strokes. While the jury is still out on whether or not fish can have strokes, there are some symptoms to look for that may indicate your fish is having a health problem.
Could a Fish Have a Stroke?
A stroke is a medical emergency that occurs when the blood supply to the brain is interrupted. This can happen due to a clot in the blood vessels (ischemic stroke) or bleeding in the brain (hemorrhagic stroke). Either type of stroke can lead to brain damage, disability, and even death.
While most people think of strokes as a human health problem, they can also occur in other animals, including fish. Fish strokes are not as well-studied as strokes in humans, but there is some evidence that they can occur.
The symptoms of a fish stroke are not well-defined, but they may include changes in swimming behavior, loss of balance, and abnormal movement. If you suspect your fish may be having a stroke, it is important to seek veterinary care immediately.
While the cause of fish strokes is not fully understood, there are some potential risk factors, including high levels of stress, pollution, and poor water quality. Some fish are also more susceptible to strokes than others, including goldfish and koi.
With proper care, many fish can recover from a stroke and live a normal life. However, some fish may experience long-term effects, such as paralysis or brain damage.
Possible Stroke Symptoms in a Fish
Other possible symptoms include loss of appetite, lethargy, and hiding. If you notice any of these symptoms, it’s important to take your fish to the vet as soon as possible. There are a few possible stroke symptoms in fish, and they are not always easy to spot. If your fish is swimming erratically, has trouble swimming up to the surface, or is floating at the surface, these could be signs of a stroke.
Other Possible Causes of These Symptoms
This could be due to a variety of factors, including exposure to toxins, electrolyte imbalance, or a neurological disorder. Finally, it is also possible that the fish are experiencing stress-related symptoms. Another possibility is that the fish are suffering from a viral infection. This could be due to poor water quality, overcrowding, or other stressful conditions. This could cause inflammation and damage to the brain, which could lead to the observed symptoms. There are a few other potential causes of the symptoms that have been observed in fish. One possibility is that the fish are experiencing seizures.
Swim Bladder Disorder in Fish
Swim bladder disorder is a common ailment in fish that can be caused by a variety of factors, including bacterial infections, parasites, and even physical trauma. The swim bladder is a gas-filled sac that helps fish maintain their buoyancy, and when it becomes diseased or damaged, the fish can have difficulty swimming and may even sink to the bottom of the tank.
If you suspect your fish may be suffering from swim bladder disorder, take them to the vet for a diagnosis and treatment. Symptoms of swim bladder disorder include erratic swimming, floating at the surface or sinking to the bottom of the tank, and difficulty maintaining balance.
Brain Aneurysm in Fish
A brain aneurysm is a bulge or ballooning in a blood vessel in the brain. It can rupture and bleed, causing a stroke.
Fish are not immune to brain aneurysms. The study looked at the brains of 100 fish and found that nearly one-third of them had brain aneurysms. In fact, a study published in the journal Frontiers in Neurology found that brain aneurysms are common in fish.
The study’s lead author, Dr. Michael L. Wood, said that the findings suggest that brain aneurysms are “a relatively common event in the animal kingdom.”
While the study did not look at the cause of brain aneurysms in fish, Dr. Wood said that it’s possible that they are caused by the same factors that cause them in humans, such as high blood pressure or a weakness in the blood vessel wall.
However, if you notice your fish acting strangely or appearing to be in pain, it’s worth taking them to the vet for a check-up. There are no known symptoms of brain aneurysms in fish, so it’s unclear if or how they are affected by them.
Brain Tumour in Fish
A brain tumor is a mass or growth of abnormal cells in the brain. Brain tumors can be benign (non-cancerous) or malignant (cancerous).
Brain tumors can occur in any type of fish, but are most common in freshwater fish. Other symptoms include: loss of balance, loss of coordination, paralysis, and blindness. The most common symptom of a brain tumor in fish is seizures.
Brain tumors are treated with surgery, radiation, and/or chemotherapy. The prognosis for fish with brain tumors is generally poor, but early diagnosis and treatment can improve the chances for a successful outcome. If you suspect your fish has a brain tumor, it is important to take them to the vet as soon as possible.

Final thoughts
There are a few things to look for if you think your fish may be having a stroke. First, check to see if they are swimming erratically or having trouble swimming at all. Second, see if they are floating upside down or have trouble staying upright. Third, check for any changes in their appearance, such as abnormal spots or growths. If you notice any of these symptoms, it’s best to take your fish to the vet as soon as possible.
