Does this look/sound like flukes?

I don,t think you would see gill flukes with your bare eyes. It's very tiny and difficult to see.

As for medication, prazipro is quite reef safe. I used it and all my invert and coral were fine, except maybe the xenia that shrinked a bit but they survived.

Also flukes don't inflate and deflate. If that think is big enough for you to see it inflate and deflate, I doubt it's a fluke.

It is very tiny and hard to see, but the other side has no bubble. It just looks like an open... well, gill. So now I'm wondering if it is a gill fluke?
