Angelfish Swimming Sideways: Causes and Solutions Explained

Last Updated on 2023-12-18

Angelfish are a popular and attractive species of freshwater fish that can make a beautiful addition to any aquarium. However, if you notice your angelfish swimming sideways, it could indicate an underlying health issue that requires immediate action. In this article, we will explore why your angelfish may be swimming sideways and what steps you can take to help them.

Why Is Your Angelfish Swimming Sideways?

Angelfish are well known for their graceful swimming style. However, if you notice your angelfish swimming sideways, it could indicate an underlying health issue. Here are the reasons why your angelfish may be swimming sideways and what you can do to help them.

Swim Bladder Disease

One common reason for angelfish swimming sideways is swim bladder disease. This affects the fish’s ability to control its buoyancy, causing it to swim erratically or struggle to stay upright. Swim bladder disease can be caused by several factors, including overfeeding, poor water quality, and bacterial infections.

To prevent swim bladder disease in your angelfish, ensure not to overfeed them and maintain proper water quality in your aquarium. You should also avoid feeding them food that is too high in protein, as this can be difficult for their digestive system to process.

Spinal Deformity

Another possible cause of sideways swimming in angelfish is a spinal deformity. This can be genetic or caused by injury or stress, resulting in curvature or twisting of the spine, affecting the fish’s ability to swim normally.

Unfortunately, there isn’t much that can be done to treat spinal deformities in fish. However, you can still provide a comfortable environment for your angelfish by ensuring they have plenty of hiding spots and plants in their aquarium.

Poor Water Quality

Poor water quality is another potential cause of sideways swimming in angelfish. High ammonia or nitrate levels can lead to stress and illness among fish which can cause them to exhibit unusual behavior, such as swimming sideways.

To prevent poor water quality in your aquarium, make sure to perform regular water changes and test the water regularly for ammonia and nitrate levels.

Behavioral Quirks

If your angelfish is swimming sideways but exhibits no other symptoms, such as loss of appetite or unusual behavior, it may simply be a harmless quirk of the fish’s behavior. Some fish develop unusual swimming habits as a result of their unique personalities or interactions with other fish in the tank. However, monitoring your fish closely and consulting with a veterinarian or experienced aquarium hobbyist is always a good idea if you have any concerns about their health.

What Are the Symptoms of Swim Bladder Disease in Angelfish

As an angelfish owner, it is important to know the symptoms of swim bladder disease to identify and treat the condition early on. We’ll discuss the most common symptoms of swim bladder disease in angelfish.

Difficulty Swimming

One of the most noticeable symptoms of swim bladder disease in angelfish is difficulty swimming. Affected fish may have trouble maintaining their balance or staying upright in the water. They may also swim in circles or have an erratic swimming pattern. If your angelfish is struggling to swim, this is a clear sign that something is wrong, and it may be swim bladder disease.

Buoyancy Issues

Another symptom of swim bladder disease in angelfish is buoyancy issues. This can include floating to the top of the tank or sinking to the bottom, which can make it difficult for the fish to swim normally. In severe cases, the fish may be unable to swim at all, leading to more serious health problems.

Loss of Appetite

Swim bladder disease can also cause a loss of appetite in angelfish. Fish that are suffering from this condition may stop eating or show a decreased interest in food. If your angelfish is not eating normally, it may indicate swim bladder disease or another health issue.

Swollen Abdomen

A swollen abdomen is another symptom of swim bladder disease in angelfish. A build-up of gas can cause this in the swim bladder, which can cause the fish to become bloated. The swollen abdomen may also be accompanied by other symptoms, such as difficulty swimming or buoyancy issues.

Lethargy

Fish that are suffering from swim bladder disease may also become lethargic or less active than usual. This can be a result of the fish’s inability to swim normally or the discomfort caused by the condition. If your angelfish is spending more time than usual resting at the bottom of the tank, it may be a sign of swim bladder disease.

How Do You Treat Swim Bladder Disease in Angelfish?

If you suspect your angelfish has swim bladder disease, it’s important to take action promptly to identify and treat the underlying cause. In this article, we will explore some of the ways you can treat swim bladder disease in angelfish.

Isolate the Affected Fish

The first step in treating swim bladder disease in angelfish is to isolate the affected fish from the rest of your tank. This will help to prevent the spread of any infections or diseases and make it easier to monitor the fish’s behavior and symptoms. You can use a quarantine tank or a separate container to house your fish during treatment.

Identify the Underlying Cause

Before treating swim bladder disease in your angelfish, it’s essential to identify the underlying cause of the condition. This can be challenging because there are several possible causes, including overfeeding, poor water quality, bacterial infections, and physical injuries. Once you have identified the cause of your fish’s swim bladder disease, you can take steps to address it directly.

Adjust Feeding Practices

Angelfish require a balanced diet that contains all the necessary nutrients to maintain good health. Feeding your fish a high-quality diet of pellets, flakes, and live or frozen foods will help to boost their immune system and promote healing. Avoid overfeeding your fish, as this can contribute to constipation, which can worsen swim bladder disease symptoms.

Improve Water Quality

Angelfish are sensitive to changes in water conditions, and poor water quality can contribute to swim bladder disease. To help your fish recover, you should monitor and adjust the water conditions in the quarantine tank. Ensure that the water is clean, free of debris, and maintain stable water parameters, including temperature, pH, and ammonia levels.

Medications

If your angelfish has a bacterial infection that is causing its swim bladder disease, medications may be necessary to treat the underlying condition. Some medications, such as antibiotics or anti-parasitic drugs, may be prescribed by a veterinarian or fish specialist. Always follow the medication instructions carefully and avoid using any treatments that are not specifically designed for angelfish.

Epsom Salt Baths

Epsom salt baths are another treatment option for swim bladder disease in angelfish. The magnesium sulfate in Epsom salts helps reduce inflammation and swelling around the affected area while improving circulation throughout the body. To administer an Epsom salt bath, dissolve 1 tablespoon of Epsom salts per gallon of aquarium water and soak your fish for up to 20 minutes.

Monitor Progress

Once you have isolated and treated your angelfish for swim bladder disease, monitoring their progress closely is important. Check their behavior, appetite, and overall health regularly to ensure that they are recovering as expected. If you notice any changes or worsening of symptoms, you may need to adjust the treatment or seek further advice from a veterinarian.

How To Prevent Your Angelfish from Swimming Sideways in The Future

If you want to prevent your angelfish from swimming sideways in the future, there are several steps you can take to help keep them healthy and happy. Let’s go through each of them.

Maintain Good Water Quality

The first and most important step in preventing swim bladder disease in angelfish is maintaining good water quality in your aquarium. This means keeping the water clean and free of debris and maintaining stable water parameters such as temperature, pH, and ammonia levels. Regular water changes and a good filtration system can help to keep the water in your tank clean and healthy for your angelfish.

Avoid Overfeeding

Overfeeding your angelfish can contribute to swim bladder disease, as well as other health problems. To prevent this, feed your fish a balanced diet of pellets, flakes, and live or frozen foods in small, frequent meals throughout the day. Avoid feeding them more than they can eat in one sitting, and remove any uneaten food from the tank after a few minutes.

Provide Adequate Space

Angelfish are active swimmers and require a lot of space to move around freely. If your tank is too small, your angelfish may become stressed and more prone to swim bladder disease. Ensure that your tank is large enough to accommodate your fish and provide plenty of hiding places and swimming areas.

Consider Genetics

Swim bladder disease can be genetic, so if you’re purchasing angelfish, be sure to choose healthy specimens from a reputable breeder. Avoid purchasing fish exhibiting signs of swim bladder disease, such as swimming sideways or having difficulty swimming.

Quarantine New Fish

When introducing new fish to your aquarium, it’s important to quarantine them first before adding them to your main tank. This helps prevent the spread of diseases and infections that could affect the health of your existing fish.

Monitor Your Fish

Regularly monitoring your angelfish for signs of swim bladder disease can help you catch and treat the condition early on. Look for symptoms such as difficulty swimming, buoyancy issues, loss of appetite, swollen abdomen, and lethargy. If you notice any of these symptoms, isolate the affected fish and seek treatment promptly.

Consult with a Veterinarian

If you suspect your angelfish has swim bladder disease or any other health issues, it’s essential to consult with a veterinarian who specializes in aquatic animals. They can provide you with advice on how best to treat the condition based on its underlying cause.
