Fairy Wrasse Experience

[BCOrchidGuy]

I added an Orange Shoulder Tang with out putting it in isolation and wiped out everything. I noticed the tang had some spots on it the day after I got it, and kept watching, my other tang developed some spots too so I treated the tank with Greenex, with in 24-48 hours I had lost most of my fish, by the time I got the tank ripped apart and caught the remaining fish and put them into isolation I had lost everything except a Solaris goby. At first I thought it was Ick but seeing how fast it spread and how quickly the fish died I have to assume it was Amyloodium or something worse.
I lost everyone of my fish except that solaris goby, oh and of course the Clarkii clowns I had in a seperate tank. I even had some tomato clowns in my refugium and lost them both quickly as well so what ever it was was virulent. Now I have a Sailfin tang and two Tomato clowns in isolation, and the two Clarkii's. I can't prove the Orange Shoulder brought this on but I had no sign of illness before I got it, and I hadn't added any new fish in over a month, so I am making the assumption that the new fish brought in a pathogen that wasn't apparent when I bought the fish. I called the store I bought it at and they said sorry but they doubt the fish caused the problems as they treat all their fish tanks with a bit of copper. They figure the illness was there before the new fish came in.
As far as the Fairy wrasses, they were simply beautiful fish, I may get more, or I may go with another small wrasse and just get a school of 6 or 8.....
