My sailfin tang I have had for about 2 months. He had ich when I first got him I tried catching him but it was impossible so I just left him in their so life can take its course but after a month the ich went away and the other day I tried to install protein skimmer and I guess I scared him a bit now he looks a bit pail sometimes but not all the time and he has a couple white dots. Can it go away on its own? Cause I thats pretty much what I did last time he also eats normal and I put in garlic extreme and feed him good food. Can he fight it off without me having to take it out and also I am not exactly sure if it is ich cause ich is really small white dots but these are small and medium size but idk. Please comment and help thanks.
