So this is crazy but I can't figure what's going on...my tank parameters are in check. My purple tang and kole eye have ich.

I have never had a problem with ich in the past and I have narrowed it down to two things:

1) My temp... has been unstable the last few days with 5+ swing... I added another heater to help stabilize the low temps

2) This one is going to sound crazy but I think the ich could have been caused by the stress my fish may have gotten as a result of the LOUD Karoake playing over the last 3 days (continuous play). The tank and PS3 are in the same room...living room.

Your thoughts...?
