But if caught early enough, most diseases are easily treated. Use at the first sign of your fish behaving unusually or appearing to be unwell. Signs of disease are ragged or blood streaked fins, unusual swimming action or loss of balance, cotton wool-like growths, slimy white skin or fins, cloudy eyes, white spots, lying on the bottom of the tank, gasping at the surface of the water, clamped fins or loss of appetite.
