My Betta fish is on its side. Is it swim bladder disease or dying?

Updated On September 23rd, 2025

Pet's info: Fish | Unknown - Fish | Male | unneutered | 2 years and 7 months old

Ice is sitting at the bottom of the tank on his side. I thought maybe he had swim bladders disease. We have gone 2 days now without feeding him and i tried one pea without skin. I think he may be dying just want to be sure i am doing everything possible for him. We changed his water 2 days ago and he has a filter. He doesnt seem to have any energy to swim at all. Any suggestions?

Check the water chemistry. Use a home test kit or submit a water sample for testing. The local Petco may do this for free or for a small fee. Aim for an absence (0 ppm) of ammonia and nitrites. Nitrates should be 20 ppm or less. Check the water temperature as well. Bettas do best between 78 F and 80 F. Low temps can affect appetite and activity in fish. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. Drop the water level to make it easier for Ice to surface.
