Thankfully, swim bladder disease can be treated, and we’re here to tell you some of the different ways that you can help.

  • Separate From Other Fish : If you keep your Arowana in a tank with other fish, it would be best if you separate your unwell Arowana into another tank where you can treat them separately, this might also help to destress them.
  • Reduce Feeding : Whilst your Arowana fish is being treated, we would recommend not feeding at all for the first three days. Then feeding should be minimized; this means cutting the amount of food that you would usually provide them. Start small, and once your Arowana fish is getting better, you can start to increase the amount you feed it slowly.
  • Change The Water Conditions : You’ll need to change the water conditions whilst treating your Arowana fish, and this is why we suggest that it is best being separated from the other fish. The water temperature during treatment needs to be between 78 and 80 degrees Fahrenheit.
  • Add Aquarium Salt : Add aquarium salt to your Arowana’s tank. The chosen type of salt that you purchase will display the correct dosage for you to use.
