I have recently upgraded my 100 gallon reef to a 180 gallon reef. The transfer went great and the tank has been running great untill recently I introduce a red tail trigger about two monthes ago. I noticed right away that his top fin was a little blotchy and thought nothing about it. Know it looks like ich he is covered with a dust like specs. I also just lost 2 fish in the last few days. The others are eating very well. Is there a chance Ich can just be eliminated with out quarantine
