Possible causes of your betta fish's behavior could be:
Swim Bladder Disease: A condition that affects the fish's ability to swim properly. It can be caused by various factors, including bacterial infection, constipation, or injury. Symptoms include floating at the surface of the tank, sinking to the bottom, or struggling to maintain balance.
Constipation: Bettas can become constipated due to a diet high in protein and low in fiber, or from eating indigestible objects. Symptoms include a swollen belly, lack of appetite, and lethargy.
Bacterial Infection: Bettas can be susceptible to bacterial infections, which can affect various parts of the body. Common symptoms include lethargy, loss of appetite, clamped fins, and changes in coloration.
Water Quality Issues: Poor water quality, such as high levels of ammonia, nitrite, or pH imbalances, can cause a variety of health problems for bettas. Symptoms can include lethargy, loss of appetite, gasping at the surface, and gill damage.
Stress: Bettas can become stressed due to various factors, such as overcrowding, lack of hiding spaces, or changes in water conditions. Stress can lead to a weakened immune system and make the fish more susceptible to illness.
Underlying Health Conditions: Bettas may also be experiencing underlying health conditions, such as organ failure or parasites, which can cause them to stay at the bottom of the tank and appear sick.
Recommendations
To determine the exact cause of your betta's behavior, it is advisable to observe the fish closely and monitor the water parameters of the tank. If you suspect a health problem, it is best to consult with a veterinarian or an experienced aquarist for proper diagnosis and treatment. Here are some recommendations based on the potential health problems mentioned:
For Swim Bladder Disease:

- Provide a varied diet with a balance of protein and fiber.
- Avoid sudden changes in water temperature or pH.
- If symptoms persist, consult with a veterinarian for possible medication or surgery.
For Constipation:
- Feed the betta a high-fiber diet, such as daphnia or brine shrimp.
- Avoid overfeeding and ensure food is appropriate for the fish's size.
-Gently massage the betta's belly to help release any trapped air.

For Bacterial Infections:
- Identify and treat the underlying cause of the infection, such as poor water quality or injury.
- Use appropriate medications, such as antibiotics, under the guidance of a veterinarian or experienced aquarist.
- Maintain good water quality and hygiene to prevent future infections.
Water Quality Issues:
- Regularly test the water parameters, including pH, ammonia, nitrite, and nitrate levels.
- Perform partial water changes as needed to maintain water quality.
- Use a water conditioner to remove chlorine and other harmful substances from tap water.
- Consider investing in a filtration system to help maintain water clarity and remove impurities.
Stress:
- Provide a suitable environment for the betta, including a tank of appropriate size, hiding places, and live plants.
- Avoid overcrowding the tank.
- Minimize disturbances and sudden changes in the environment.
- Ensure the water temperature and pH are stable and within the recommended range for bettas.
Underlying Health Conditions:
- If you suspect an underlying health condition, consult with a veterinarian or experienced aquarist.
