i woke up this morning and caught that my scopas tang caught icy had lots of white dots on him and was on his fins my previous butterfly fish die from this so i went and bought herbtana because it is reef safe so they say i dosed it and my corals all look fine with no signs of stress and the icy seemed to have fall off my fish already!!! it may be because i caught it early but im still going to follow the 10 day process
