Clownfish problems

[Xxmxxh1]

Hi i was wondering if any one can tell me what signs to look out for when your clownfish is behaving funny or when its ill. What symptoms should i look out for

It depends on the clownfishs normal behavior. Generally though they will become lethargic and just lay somewhere, flashing (scratching or rubbing on stuff in the tank) loss of appetite.
