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??
