Stupid Ich or stupid fish? ..stupid owner

My cleaner wrasse rocks...she eats tons of cyclopses, shrimp, and the yellow shoulder tang loves to get cleaned...I have no worries about her doing well...but the concern does not go unheard.

Kich-ich I've heard so many mixed reviews. There are mixed reviews on everything because there are so many varieties of ich, how long has the fish had it, how deep is it, etc....

So here's my questions...if I pull the Hippo out, since she is the only one that has ich, and the others are immune or able to fight it...and wait the 8 weeks, when I put her back in there, will she just get it again, because the ich just isn't visible in the other fish?

 

Ive got a hippo and it has had ick. I use garlic guard and kept fed and it fights it right off. I had a powder blue and it got ick. didnt look that bad but died within 2 days. My other LFS will not even carry the powder blue tangs due to this. keep it fed and try to keep it from getting stressed and she should be fine. I have used Kick-Ick in the past with no harm to my tank.
