I seldom use any medications, so I can't recommend any.
And I find unless I know whether a bacteria is gram neg, or gram pos makes a big difference in what to use so for treatment, so if a fish becomes seriously compromised, and I can't determine what species of bacteria, I simply euthanize it.
For me its all about prevention, which means what some may call "excessive" water changes, and long quarantine periods.
If I get a new fish, I quarantine for at minimum 4 months.
I have had fish came back that looked pretty bad when I first got them using only frequent large water changes.
I had a group of breidhori arrive, and the stress of shipping brought on lymphocistus, which is viral (no medication would be effective) it disappeared with only water changes.
Some things like injuries nd true scars, don't come back though, scars (just like on humans) may be permanent, some heavy HITH holes may belong in that category.
If fins are ripped all the way into the body, they don't repair.
In received the Paratilapia below, where the fin was damaged into the flesh, it never returned to normal.
