Heni in trouble in DT

[Quarryshark]

All. my heni who went through a full QT with a prazzi treatment as well as 30 days of CP has developed a bad case of popeye in my DT. It has progressively gotten worse in the last 3 days and the eye has a bubble in it now. She’s been in the DT for more than two months and none of my other fish (all have been properly quarrentined) are showing any signs. Could she still have flukes even though I treated her properly?
My first though is to move her and treat with erithromycin since it’s just one eye.
my QT tank has fish in CP treatment right now, so I can’t put her there and my invert QT has a group of inverts in there as well, so I have no where to put her unless I get another tank and I don’t even know where I could put a 4th.
Thoughts? TIA

Side note my LFS recommended treating the DT with either triple sulpha or melafix. Anyone have experience with either of these treatments?

When you see a shiny bubble like that in just one eye, it is almost always caused by mechanical trauma, not bacteria, so antibiotics won’t help. If both eyes and/or other fish were affected, it could be from supersaturation. If it becomes milky/cloudy then an infection is more likely.

Thank you for the post. Interestingly the eye appears to have gotten better overnight. Glad I didn’t take any drastic measures.
