Thank you medications are able to be brought just having to wait 2/3 days for delivery.
I have not done any FW Dips yet.
may local store has a fluke medication and anti bac med I may try tomorrow. If it’s in stock
I see a few things in the video:
The caudal/tail fin may have some erosion?
It is breathing very fast.
I can see the discolored area - remember that as juveniles, this species normal habitat is inside branching coral heads, so they don't get scratched "accidentally", they know how to navigate, so if you see scratches, it is typically from some other cause.
I don't like its swimming behavior, kind of odd, even for this species.
Is it still feeding o.k.?
I think you should consider treating it for flukes.
