Why Do Betta Fish Swim Sideways: Causes, Treatment & Care Tips

Betta fish are popular as pets because they are so easy to care for. They require little to no special care and are very active fish that enjoy swimming in circles. However, in some cases, you might notice that your betta fish is swimming sideways and this could be alarming.

There could be a few reasons why a betta fish is swimming sideways. One possibility is that the fish is sick with a swim bladder disease and needs to be treated. Another possibility is that the fish is trying to escape from its surroundings. If the fish is swimming sideways and it seems to be distressed, it might be best to bring it into a tank with more plants and decorations so that it has more space to swim around.

What Is Swim Bladder Disease?

Swim bladder disease is a condition where the fish’s swim bladder doesn’t function correctly. This can cause problems with breathing and digestion, as well as an inability to stay swimming properly underwater for long periods. If you notice that your betta fish is swimming in a sideways pattern or isn’t able to stay underwater for very long, it might be worth bringing it to see a veterinarian.

Causes of Swim Bladder Disease

There is no one definitive cause of swim bladder disease, but it can be caused by several factors. Some common causes include:

Overfeeding and Constipation

Overfeeding of betta fish and constipation can both cause swim bladder disease in bettas. Overfeeding leads to an accumulation of fluid in the fish’s body, including in the lungs. This causes difficulty breathing and may progress to swim bladder disease. Constipation can lead to a blockage of the fish’s intestines, which can also cause swim bladder disease.

Unstable Water Temperature

The low temperature of the tank water can also cause swim bladder disease. The cold temperatures cause nerves to freeze, which may lead to swim bladder problems.

Stress and Shock

Shock can also cause swim bladder disease. Swim bladder problems may develop after a fish is subjected to extreme stress, such as being transferred from freshwater to saltwater or being kept in an overcrowded tank.

Infection

Bacterial and parasitic infections are common and can be very unpleasant. They can lead to several different health problems, and can even be fatal. Bacterial infections are usually caused by bacteria, while parasitic infections are usually caused by parasites. Both types of infection can be treated with antibiotics, but both can also be prevented through good hygiene practices.

Chronic Injury

Chronic injury to the fish’s body can also lead to swim bladder problems. This includes injuries caused by other fish, falling objects, and rough play in the tank.

Nerve Damage

Nerve damage, either from infection or injury, can also cause swim bladder disease. This type of damage can occur anywhere in the fish’s body and may be difficult to detect. Once nerve damage has occurred, it is often difficult to treat.

Symptoms of Swim Bladder Disease in Betta Fish

Betta fish are known for their beautiful, colorful scales and their friendly personalities. However, some owners soon find out that Bettas also have a swim bladder, which is an organ located just below their stomach. Swim bladder disease is a common problem in Bettas, and it can cause several symptoms.

Swim bladder disease can cause several problems for Bettas. The most common symptom is a fish that constantly swims sideways around in its tank or aquarium. This can be frustrating for the owner, as the fish cannot be left alone and must be watched constantly. Swim bladder disease can also cause a fish to become bloated and unable to eat. In severe cases, swim bladder disease can even cause the fish to die.

Symptoms From Unhealthy Diet and Constipation

Swim bladder disease can often be the result of overfeeding or constipation. When these problems are not treated, they can cause a fish’s swim bladder to become enlarged and unsupported. This makes it difficult for the fish to swim and breathe properly, and eventually, it may die as a result.

Symptoms From Bacterial and Parasite Attacks

Bacterial and parasite attacks can also cause swim bladder disease in Bettas. When these problems are not treated, they can lead to the fish’s intestines being blocked. ̴Bacterial infections can lead to constipation, which reduces the amount of oxygen in the fish’s body. ̴Parasites will also reduce a Betta fish’s ability to breathe and eat properly. Both bacterial and parasitic infections are very common for bettas since they find it so challenging to defend themselves from such attacks and are therefore often infected with disease-carrying bacteria or parasites that allow these diseases access into their bodies.
