I'm going to feed my fish the left over bunker and clams I have when I go Striper fishing.
I've kept zebrasoma tangs and hippo tangs in tanks with ich for years, my mother has a 12 year old hippo in a tank with ich it's very resistant. If they survive the first few weeks you're usually OK4FordFamily. I did not have the gold rim tangs but for most of the life of my tank I had hippo tangs, yellow tangs, lipstick tangs and purple tangs. I didn't lose any to disease, most of them either jumped out or lived to 12+ years old and then died. I don't really like tangs and find them boring which is why I don't keep them and I am sure they live longer than 12 years. My tank has had many accidents where I killed many of the fish. My 25 year old fireclown is one of the only fish I had left after I had an accident about 15 years ago with Clorox. I posted that on various forums, maybe also this one. That day I lost a 10 year old mandarin, a 18 year old cusk eel and maybe 15 other fish. But that was due to my stupidity.
I have no problem with tangs and may get another hippo as they are the only ones I really like.
I also don't think I keep the more common fish. I have ruby red dragonettes, blue striped pipefish, clingfish, queen anthius, copperband, mandarins etc. I am also told almost every day that I am playing Russian Roulette but I am not sure how long that game lasts but 35 years disease free to me equals immunity, not just luck or my good looks which is questionable.
People also get the wrong idea about quarantining or not. I feel it is by far in the fishes better interest if the fish is in a natural tank along with the associated diseases. I feel it contributes greatly to the general health of the fish. If you read those links I posted you can see that I did not make this up. I am not that smart. I also don't think I do much different for my fish that anyone else can easily do. It is much easier to feed clams and blackworms every day than quarantine everything then treat sick fish in all sorts of medications. I buy a fish, any fish and after 10 or so minutes of acclimation, dump it in my tank. They always eat. You never saw me post that I bought a copperband or Moorish Idol and it didn't eat. In a natural, bacteria laden tank, my new fish always eat. I have never posted about my tank on a disease thread for the above reasons. All I do is feel food with live bacteria like worms, new born brine shrimp and clams. The stuff I collect is only in the summer and I think that would only help with nutrients for the corals.
I gotta see if I can get a pic here.

Get a powder blue tang and tell me in 6 months if you still feel that way.Like Paul B I have never QTd a fish in my life and or the last 25 years or so I have not had any disease in any of my tanks. Lucky you may think..... I think luck plays little part in it. I have most probably introduced the likes of white spot on more than one occasion and yes although for a few days after introducing a new fish I have seen flicking I have never seen any spots ever. I don't treat my tank unless you call the fact I use Oxydators as treatment or you consider the foods I feed and the fish oil I add to my foods some of which are home made. IME healthy fish either don't catch many of the diseases we hear about or they fend them off well before they become a major issue. Controversial, well yes but my fish live long lives and many spawn regular for me. The health of my animals speaks for itself however but I must be doing something wrong for my fish not to catch the likes of white spot.
Taken a few days ago and yes I have plenty of fish in there.
Why should I get a fish I have no interest in? Even if I got one it might get WS as other fish I have had have but then what? It would clear up in a few days anyway as my other fish have done. OK so PB are considered itch magnets but if I got one and it didnt get WS what would that prove, that I was lucky no doubt. Why isn't Paul's hippo tang full of WS? I had a tang for a month that was as black as black, I never saw a spot on it. I have plenty of other fish that are magnets for WS like my Royal grammas, copperband, damsels, torpedo gobbies. Why did my Royal grammas show WS soon after introduction only for the few spots to have disappeared along with the scratching in around 36 hours? Why aren't most of my fish full of diseases? Nobody has been able to answer the real questions here apart from Paul. Suggesting putting a PB in my tank is avoiding the real questions and is simply diversionary to just what is happening in my tank and that of a few others. The problem is it goes against the accepted norm in thinking as in you must QT or you will wipe most if not all your fish out. We aren't playing games here this is 100% genuine and we don't risk the lives of our fish which I believe is what people are doing medicating and QTing their fish. Na, I will carry on with my proven methods (to me and a few others I know) of over 25 years with a number of aquariums all with disease free long lived spawning fish, thanks.
Ich magnets is the wrong word, they are velvet magnets. If you ever get velvet like one of my tanks got, I had 10 fish die in 24 hours all because of a powder blue tang. Funny thing is the tang seemed fine until he got stressed out one day and the velvet came out of nowhere and gobbled up almost every other fish in my tank including those stupid little damsels that are supposed to be indestructible lol.
