Brown flukes? Black ich?

[JennyH3]

I have given my hippo tang a few freshwater baths in the last 2 wks. White flukes don’t come off - maybe some look white but then it’s all brown stuff. He pooped in the water ‍‍- so large chunks are poop.
Thoughts? My next step is the quarantine - I’ve done PraziPro in the tank already.
Copper power next? More Prazi in QT?
Same thing happens with my long nose butterfly - maybe a tad more white comes off tho.

Unfortunately camera is moving around too much to tell mut some of them appear to be ostracods which are grass shrimp. You can give the fish a 5 minute freshwater dip in tap water same temperature as display tank which will allow flukes if any to dislodge and you should be able to see them on bottom of dip container which look like fish scales

I can’t see anything really in the video.
Do the fish themselves show any symptoms? If so, perhaps post a video of them.
