For me, I would if it doesn't appear to be healing. For garden variety minor scuffs or injuries my typical routine is clean water, a little salt (not a lot, I'll often do in the neighborhood of a tablespoon per 30-40 gals) and/or a little Melafix. I also dose Melafix pretty lightly for minor scuffs and injuries, maybe 1/4 what the label suggests.
Before Melafix came out I'd use something with aloe, like Stress Coat. Kind of a forgotten option, but still not a bad one ime.
Nice fish!
