ICH Question

[90g-reefer]

I have only three fish in my 90 right now. 2 clowns and a hippo tang. My question is what would Ich look like. My tang is eating good but I think I see a couple of white dots on her. Bu she is so quick and hides so much I can't get a close look. But again it is hard to tell because I also have micro bubbles in the tank so I also cant tell if it is micro bubbles stuck to her. All other fish look good. Are white spots the only sign of Ich?

Sometimes it varies, but whitespots are uasuall the giveaway, but tangs can get clowdy eyes if they have ich

White grains of salt if on the skin or small white bumpy pimple lookin nodules if the ich has burrowed into the skin. Otherwise unless these two are seen then the fish may be rubbing or scratching on rocks or other hard surfaces or may be breathing rapidly if the ich has made it into the gills, notrils, etc.
