Clownfish help!!

[gtahuahua]

I have a 55 gallon tank with a Heniochus, a Foxface, and Two clownfish. This past sunday the Heniochus came down with ICH and I began to treat him with "Ick-Attack" which was reccomended by the local aquarium store to treat the tank.

Monday the two clowns began to breathe excessively. I thought that the oxygen might be depleted(seeing as how some ich medications deplete O2 levels) and so i added an aerator yesterday. However the clowns are still breathing heavily and one of them is breathing with his mouth open and they are not eating. Any suggestions??

i never liked ick attack, it worked for my gf tank but not for mine. what i used was paragaurd i believe it is by seachem. seemed to work pretty fast, one week, compared to the 3 weeks my gf had to use ick attack. and another plus is it doesnt turn your water brown, paragaurd is a litght blue color and i have only been able to find it at awannapets.
