That's not ich, but the picture isn't clear enough to say what might be going on here. Maybe a video would be clearer?

Pics are too fuzzy and at a bad angle to see. As requested by Jay, video may be better of at least 25 secs

Thank you, I have had her? For a month in a 100 gallon tank with 2 clown fish, a lawnmower blenny, a watchman phony and one that was supposed to be something else that I believe is a purple f
Dottyback(hateful heifer but never aggressive to tang). It tried & tried to get a better picture or video with no luck. Today I can’t find her so I assume she is deceased. I have kept the lights off for 2 days hoping it would help. At this point I don’t have a quarantine tank. Thank you for replying
