Swim Bladder Disease Betta: How To Identify Symptoms, Treat It, Get a Healthy Betta

Published March 25, 2024 | By Matt

Swim bladder disease (SBD) is a common issue that affects betta fish, leading to buoyancy problems and difficulty swimming. Many betta owners are concerned when their fish begins to float on its side or struggles to stay submerged. Fortunately, SBD is treatable and can often be prevented with proper care. In this guide, we’ll explore what swim bladder disease is, its causes, symptoms, and the most effective treatment methods for your betta.

Swim bladder disease (SBD) isn’t a disease in itself but rather a symptom of an underlying problem affecting a fish’s swim bladder. A swim bladder is a gas-filled organ that helps maintain buoyancy and balance in the water. When this organ becomes impaired, it leads to swimming difficulties.

SBD can result from various conditions, including overfeeding, infections, and injury, but it is not contagious.

Common Symptoms of Swim Bladder Disease

Swim bladder disease is usually easy to spot due to the distinctive behavior it causes. Symptoms include:

Difficulty swimming upright: Bettas may float on their side, sink to the bottom, or struggle to remain balanced.
Erratic swimming patterns: Some fish exhibit spiraling motions or find it difficult to stay submerged.
Lethargy and lack of appetite: The fish might appear less active, and a swollen abdomen could develop due to underlying digestive issues.
Floating Uncontrollably: Your betta may float uncontrollably to the top, sink to the bottom of the tank, or have trouble staying upright and end up laying on its side.
Sinking to the Bottom: Some bettas with swim bladder issues may rest at the bottom of the tank, unable to swim upwards.
Sideways Swimming: The fish may swim on its side or exhibit erratic swimming behaviors.
Swollen Abdomen: In cases related to digestive issues like constipation, the betta’s belly may appear bloated.
Lethargy: Bettas with SBD often become less active and show little interest in food.

It’s important to note that the bloating caused by SBD can sometimes be mistaken for a more serious condition called dropsy, which has different underlying causes and treatments.

What Causes Swim Bladder Disease in Bettas?

Understanding the root cause of swim bladder disease is essential for effective treatment. Common causes include:

Overfeeding and Constipation: One of the most frequent causes, overfeeding leads to digestive issues that press on the swim bladder, impairing its function.
Water Quality and Temperature: Poor water conditions or sudden changes in temperature can shock the betta, contributing to swim bladder dysfunction. A stable temperature between 78-82°F is crucial for their well-being.
Infections and Trauma: Bacterial infections or physical injuries can inflame the swim bladder or damage it directly, leading to buoyancy issues.
Genetics: Some bettas, particularly those with exaggerated finnage, may be genetically predisposed to swim bladder issues.

Effective Treatments for Swim Bladder Disease

The treatment for swim bladder disease depends on the cause but typically follows a multi-step approach:

Fasting: Begin by fasting your betta for 1-3 days. This gives the digestive system time to clear any blockages that may be causing pressure on the swim bladder.
Dietary Adjustments: After fasting, offer a small, cooked, deshelled pea or fiber-rich foods like daphnia. These act as natural laxatives and can help relieve constipation.
Water Conditions: Ensure the water temperature is stable around 80°F and keep the tank clean by performing regular water changes. Pristine water conditions are essential for a speedy recovery.
Medical Treatment: If the cause is a bacterial infection, antibiotics may be necessary. It’s important to consult a vet for severe or persistent cases.

How To Treat Swim Bladder

While SBD can be severe, there are several steps you can take to help your betta recover:

Dietary Changes:

A temporary fast of 2-3 days can be beneficial. This allows the fish to clear its digestive system, potentially easing pressure on the swim bladder.
After fasting, introduce a small piece of cooked, deshelled pea. The pea’s fiber can act as a gentle laxative to help with constipation, a frequent contributor to SBD.

Adjust Water Temperature:

Gradually raise the water temp to around 80°F (27°C). This warmer environment can enhance your betta’s metabolic rate and bolster its immune system, which may aid in the natural recovery process.

Epsom Salt Bath (Optional):

In some instances, a short bath in Epsom salt (approximately one tablespoon per gallon of water for 10-15 minutes) can be helpful. This can alleviate inflammation and may also assist with constipation. Be sure to monitor your fish closely during this process and stop if they show signs of distress.

Common Mistakes to Avoid When Treating SBD

While treating swim bladder disease, there are a few common misconceptions to avoid:

Salt Treatments: Aquarium salt is only useful for treating bacterial infections, not for swim bladder disease. It’s important not to rely on salt unless specifically treating an infection.
Pea Treatments: Feeding peas can help with constipation but is not a cure-all for SBD. If constipation isn’t the root cause, feeding peas could be ineffective.

Preventing Swim Bladder Disease in Bettas

Preventing SBD involves proper care and a balanced environment for your betta:

Maintain a Clean Tank: Regular water changes and monitoring water parameters are crucial in keeping your betta healthy. Proper filtration and ammonia control are essential to avoid stress and infection.
Feed a Balanced Diet: Bettas thrive on a varied diet that includes high-quality pellets and occasional live or frozen treats like bloodworms.
Stable Environment: Keep the water temperature stable, avoid overcrowding the tank, and reduce stress by providing hiding spots and a calm environment.

When to Seek Professional Help

If your betta’s condition doesn’t improve after initial treatments, or if symptoms worsen, it’s time to seek veterinary advice. Severe cases, particularly those involving infections or organ damage, may require professional intervention.
