had one of these once duce ,added him to the tank as the last fish to complete the reef when I first started up again, he got ich ,which I treated with oodinex but the end result was they all got it and I lost all my fish bar 2 pajama cardinals before I could eradicate it and had to start all over again.(beware unless you have a ultra violet sterilier or oziniser on your system.)casualties were 2 clowns .regal tang, powder blue tang, blue throat triggerand a mandarin,it was realy heartbreaking watching them die and not being to do anthing about it,(so think twice before adding one to your system).
