Is this ich? What to do? REPOST

[liamelias]

Hey guys. I’m 99% positive my clowns have ich but asking for advice. I’ve had my clowns for a month and a half. They are the only fish in the tank. About almost 2 weeks ago I started noticing the dreading tiny white spots which now have started covering the fish. Im not sure what to do. They’re still feeding great, very active and hungry. No weird behavior. I wonder if they are hardy enough to ride it through or should I setup a QT for them? Just afraid the QT will actually stress them out to the point they succumb to the disease. Any thoughts?
Here is a video under white light that clearly show their white spots as they’re swimming
