Clamped fins are a sign of stress. This can be due to water quality or low water temperature. Ideally, a Betta should be kept in a tank no smaller than 2 gallons. A filter is recommended but water changes (using aged or conditioned water) can be done every week or two to maintain water quality. A heater is essential. Bettas do best between 78 F and 80 F. Feed him a good quality pelleted food, Hikari pellets are recommended.
