Check the water temperature. Bettas do best between 78F and 80F. Low temps can affect activity in fish. You may need a small submersible heater to maintain water temperature. Next, check water chemistry. You can do this with a home test kit or by submitting a water sample for testing. Most pet stores will do this for free or for a small fee. Confirm an absence (0ppm) of ammonia and nitrites with a nitrate level of 40ppm or less. Partial water changes may be indicated to stabilize chemistry and maintain water quality. Use only aged or conditioned water that is temperature matched to prevent stress or shock.
