They are very very hardy fish due to their thick slime coat and ich cannot easily penetrate it. Angels and tangs are complete opposite. Now, would it be good to QT all fish? Absolutely.
The best way to do it in a QT is to put live sand in tupperware for a leopard wrasse to sleep in or for a diamond goby to sift. Putting a fish like that in a bare bottom tank is in my opinion cruel. I have seen diamond gobies and leopard wrasses in BB tanks at a fish store. You know what they look like? Sick and depressed. A sand burrowing wrasse can actually damage its mouth in a BB tank and that will cause more harm than good.
Back to my reasoning... If you treat fish preventively with medicine like I do, that live sand cannot be put back in the DT. Even if no treatment is done I would still not put the sand back and just get rid of it. That's a lot of sand to throw away every time you add a goby or a wrasse. Might it be worth the expense? Many might say yes but I don't think so. My reasoning is based on personal experience, talking to LFS
owners (yes plural) and online research.
