Understanding Popeye in Bettas

Fish owners should take any signs of Popeye seriously, as it can lead to further health problems in bettas. In this article, we will delve deeper into what Popeye is, what causes it, and the symptoms to look out for in your bettas.

What is Popeye? Popeye is a condition in which your bettas’ eyes appear to bulge out or become inflamed.

This is caused by the buildup of fluid in the eye socket. Popeye is most commonly seen in bettas, but it can also occur in other types of fish.

Causes of Popeye

There are various reasons why bettas might develop Popeye. The most common causes include injury, infection, and disease.

Injury-related Popeye

Injury-related Popeye can be caused by sharp objects or rough surfaces in the aquarium. Bettas might accidentally hit their face against tank decorations or rocks, causing trauma to the eye socket.

Infection-related Popeye

Infection-related Popeye is caused by bacterial or fungal infections. These infections can enter the fish’s body through wounds or cuts, eventually leading to inflammation of the eye socket.

Dirty water in the aquarium can also be a cause of infection-related Popeye.

Symptoms of Popeye in Bettas

Cloudy Eye

One of the first symptoms of Popeye in bettas is when the eye becomes cloudy. Cloudy eyes in fish are a sign of inflammation, and this may be the first indication of Popeye.

Red Eye

Another symptom of Popeye is a red or irritated eye. When the eye is inflamed, the blood vessels in the eyelids may also become irritated and swell, causing a red or pinkish appearance.


Popeye can cause your bettas discomfort and pain. They may show signs of irritation, such as rubbing their eyes against the tank’s surfaces.

Treatment for Popeye

Treating Popeye in bettas will depend on the underlying cause. Here are some steps to resolve this condition:

Clean Water

Check the water quality in the aquarium and ensure that it is clean. Water changes can remove any bacteria or fungus that may be causing Popeye.


If the cause of Popeye is a bacterial infection, antibiotics may be prescribed by a vet.

Salt Baths

Adding a small amount of aquarium salt to the water can also prevent bacterial infections and help speed up the healing process.


Bettas are hardy and resilient fish, but they still need to be taken care of well. Popeye is a common condition that can occur in bettas, but it can be prevented.

Ensuring that your tank is clean and free from any sharp objects or rough surfaces can go a long way in keeping your bettas healthy. If you do notice any symptoms of Popeye, seek the advice of a vet or experienced fish hobbyist.

Treatment for Popeye is available, and with care and attention, your bettas will soon be back to their active and playful selves.
