Check water chemistry. Use a home test kit or submit a sample for testing. Most pet or fish store will do this for free or for a nominal fee. Elevated ammonia or nitrites may cause the symptoms reported. Daily water changes will be necessary to correct imbalances. Use only aged or conditioned water that is temperature matched to prevent further stress or shock. Check the water temperature as well. Bettas do best between 78 F and 80 F. If your filter has an adjustable flow, turn it down to a weak current.
