Symptoms of Swim Bladder Problems: Abnormal swimming or difficulty maintaining equilibrium.
Problems with the swim bladder are usually indicative of one of the issues listed below. If the swim bladder seems to be a problem then you should check for the following listed conditions:
Bladder deformity (congenial defect)
Tuberculosis or cancer in the swim bladder or surrounding organs or tissue.
Improper nutrition or lack of nutrition
Repeated or rapid changes in water temperature or parameters
If you are unable to determine the exact cause of the swim bladder issue, the best bet is to treat the fish for constipation. Feed a regular diet of live foods to see if it will help the fish overcome the constipation. Keep an eye out for signs of bacterial infection or parasitic infestation.
