i have used kick-ich for 2weeks as said to and then still saw my tang twitching. i moved my blue tang to QT for cupramine treating for a week and everything has stopped but heavy breeding and believe he is ok now i have readded him to the display but i would like to know if kick-ich has worked for anyone because it seemed to remove the spots but the tang still twitched however that was in my 36 and its a juvie. now i moved it into my 90 gallon and hope 2 see it all well 2moro moring. any input?
