i have had my clown fish for about 3 weeks now and there are little white dots on her gills and nose. at first i thought it was ich. but it should have spread to my other fish by now and so far there are no signs of illness or the same white dots on any of my other fish. she doesnt act sick and her behaviour has not changed since i got her and she is quit active and courious. by now it is too late to quarintine her obiously so i was just wondering how i should go about this. ive attached the best picture i can get
