Lethargy and clamped fins in a betta fish are common signs of stress or illness. Start by checking your water parameters: temperature (betta prefer 78-80°F), ammonia, nitrites, and nitrates. Poor water quality is a frequent cause of health issues. Ensure your tank is cycled and perform a partial water change if parameters are off. Observe for other symptoms like white spots (ich), velvet-like coating, torn fins, or difficulty swimming. It could be fin rot, a bacterial infection, or a parasitic issue. Improving water quality is often the first step, but if no improvement or other symptoms appear, medication may be necessary.
