Check water temperature. Low temps can affect activity and appetite in fish. Bettas do best between 78 F and 80 F. Next, check water chemistry. This can be done using 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 (0ppm) of ammonia and nitrites with nitrates at 20ppm or less. Perform partial water changes to stabilize chemistry and/or to improve water quality. Use only conditioned water that is temperature matched to prevent stress or shock.
