How do you save my betta fish if it is floating on its side?

I'm sorry to hear your betta is struggling! It's important to act quickly when a betta is floating on its side, as it's a sign of serious distress.

However, I'm not a veterinarian. I can't give medical advice.

Please contact a qualified veterinarian or fish specialist immediately. They can diagnose the problem and recommend the best treatment.

Here are some general things you can do while waiting for professional help:

* Isolate your betta: Move the betta to a separate tank or container with clean, dechlorinated water. This will help prevent the spread of any potential infections.

* Monitor the water parameters: Check the temperature, ammonia, nitrite, and nitrate levels. Any fluctuations could be contributing to the betta's illness.

* Observe your betta's behavior: Note any other symptoms like lethargy, loss of appetite, or discoloration. This information can be helpful for the vet.

Possible causes for a betta floating on its side include:

* Swim bladder disorder: This is a common problem in bettas, and it can be caused by a variety of factors, including constipation, bacterial infections, and parasites.

* Internal parasites: Internal parasites can cause inflammation and damage to the betta's organs, leading to weakness and difficulty swimming.

* Water quality issues: Poor water quality can lead to stress and illness in bettas, making them more susceptible to other problems.

* Injury: A betta could have been injured by a tankmate, a sharp object in the tank, or even by being mishandled.

Please remember that prompt action is key to helping your betta recover. Contact a vet or fish specialist for professional diagnosis and treatment.
