    Fins clamped
    Velvet, whitespot or toxins

    Fins constantly erect

    Severe loss of balance
    Swim bladder disease

    Gasping at surface
    Water too hot, lack of oxygen (O²), excessive carbon dioxide (CO²) or toxins

    Sudden dashes, even out of water
    Lice, flukes, low pH or toxins

    Unusual colours, dark colours

    u should rather move the fish to a QT tank, if u have one, and slowly lower the salinity to 1.010...( google: hypo salinity )
