Help - it looks like I have a growing ich outbreak in my 120g reef. It all stared about 4 days after adding a new kole tang to the tank - he had been quarntined for about 10 days in my dealers cooper treated tank and looked fine. About 2 days after being put in my tank (water parameters are ideal and proper acclimation techniques were followed), the kole tang broke out with ich and ultimately some body leasions. I could not catch him with all the rock work - he ultimately died (I assume since he's been missing for a week and was probably consumed by my serpent/brittle stars). In the last 2 days, my purple tang (has been in the tank for 3 years) and strawberry dottyback are showing signs of ich. There is no way to catch them in this tank to attempt to quarantine. The other fish (pecula clowns, green chromis and lawnmower blenny) appear fine, thus far. The corals are all fine. What, if anything, can I do. I have 1 cleaner shrimp in residence. I can't use copper treatments because of the inverts. Can I sit this out (I do use UV 24/7 in the tank)
