I'm sure there are people on this forum who QT everything that is wet (including corals and inverts), but I've never met anyone who does that. I absolutely QT all of my new fish and treat prophylactically with copper power, but I never QT corals or inverts.
Is there a risk in not doing so? Sure. But that just seems exhausting. And after 20 years in the hobby it hasn't bitten me in the butt yet, so no plans to change.
