Check the water temperature. Bettas are tropical fish and do best between 78F and 80F. Low temps can affect activity in fish. If temperature is normal, check the water chemistry and perform a water change if necessary. Use only aged or conditioned water that is temperature matched to prevent stress or shock.

Bettas are not particularly active swimmers and it is not uncommon, especially for male Bettas to lie on their side. Keep in mind that male Bettas have large flowing finnage that are rather cumbersome to mange. Some Betta may rest tucked in between leaves of plants or aquarium décor to support their fins. That being said, it is important to always monitor water parameters to ensure ideal water conditions. Poor water quality including low or extremely high water temperatures can contribute to lethargy and overall lack of vitality. Be sure your Betta setup it properly filtered to ensure best living conditions.
